 Exhibit 4.7 

WARRANT AGREEMENT 
 THIS
WARRANT AGREEMENT (this “Agreement”), dated as of [•], 2022, is by and between LMF Acquisition Opportunities, Inc., a Delaware corporation (the “Company”), and Continental Stock
Transfer & Trust Company, a New York limited purpose trust company, as warrant agent (the “Warrant Agent,” also referred to herein as the “Transfer Agent”). 

WHEREAS, on April 21, 2022, the Company and SeaStar Medical, Inc., a Delaware corporation (“Target”) entered into
an Agreement and Plan of Merger (the “Transaction Agreement” and the transactions contemplated by the Transaction Agreement, the “Transaction”) by and among, the Company, Target, LMF Merger Sub, Inc.,
a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”), and certain other parties named therein, pursuant to which, among other things, Merger Sub will merge with and into Target with Target
surviving the merger as a wholly-owned subsidiary of the Company; 
 WHEREAS, on August 23, 2022, the Company entered into that certain
Subscription Agreement with [____] (the “Subscriber”) (the “Subscription Agreement” and the transactions contemplated by the Subscription Agreement, the “Offering”), pursuant to
which the Subscriber agreed to subscribe for and purchase, effective as of the closing date of the Transaction (the “Transaction Closing”), [______] shares of the Company’s Class A Common Stock, par value $0.0001
per share (the “Common Stock”), for a purchase price of $10.00 per share of Common Stock, and [______] private placement warrants to purchase one (1) share of Common Stock at an exercise price of $11.50 per share (the
“Warrants”); 
 WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant
Agent is willing to so act, in connection with the issuance, registration, transfer, exchange and exercise of the Warrants; 
 WHEREAS, the
Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of
the Warrants; and 
 WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on
behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement. 

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: 

1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the
Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. 

2. Warrants. 
 2.1 Form
of Warrant. Each Warrant shall be issued in registered form only, and, if a physical certificate is issued, shall be in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and shall be signed by, or
bear the facsimile signature of, the Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer, Secretary or other principal officer of the Company. In the event the person whose facsimile signature has been placed upon any
Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. Each Warrant shall
bear the restrictive legend set forth in Exhibit B. 
 2.2 Effect of Countersignature. If a physical certificate is issued,
unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant certificate shall be invalid and of no effect and may not be exercised by the holder thereof. 

2.3 Registration. 
 2.3.1
Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants,
the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. All of the Warrants shall
initially be represented by one or more book-entry certificates (each, a “Book-Entry Warrant Certificate”). Upon registration of the Company Common Stock issuable upon exercise of the Warrants with the U.S. Securities and
Exchange Commission (the “Commission”) pursuant to the terms of the Subscription Agreement between the Company and the holder of the Warrants, the Warrant Agent shall use commercially reasonable efforts to deposit the
Warrants with The Depository Trust Company (the “Depositary”) and register the Warrants in the name of Cede 

 
& Co., as nominee of the Depositary. Following such deposit, ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through,
records maintained by: (i) the Depositary or its nominee for each Book-Entry Warrant Certificate, or (ii) institutions that have accounts with the Depositary (each such institution, with respect to a Warrant in its account, a
“Participant”). 
 If the Depositary subsequently ceases to make its book-entry settlement system available for the
Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form,
the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive
certificates in physical form evidencing such Warrants (“Definitive Warrant Certificate”). Such Definitive Warrant Certificate shall be in the form annexed hereto as Exhibit A, with appropriate insertions,
modifications and omissions, as provided above. 
 2.3.2 Registered Holder. Prior to due presentment for registration of transfer of
any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (each such person, a “Registered Holder”) as the absolute owner of such Warrant and
of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on a Definitive Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all
other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 
 2.4 No Fractional
Warrants. The Company shall not issue fractional Warrants. If a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down to the nearest whole number the number of Warrants to be issued to such holder.

 2.5 Warrants. Subject to the provisions of this Agreement, the Warrants shall be identical to the Public Warrants (as defined
below), except that so long as they are held by the Subscriber or any Permitted Transferees (as defined below), as applicable, the Warrants: (i) may not be transferred, assigned or sold until thirty (30) days after the Transaction Closing;
and (ii) shall not be redeemable by the Company. 
 3. Terms and Exercise of Warrants. 

3.1 Warrant Price. Each Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this
Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this
Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share at which shares of Common Stock may be purchased at the time a Warrant is exercised. The Company in its sole
discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business Days, provided, that the Company shall provide at least twenty (20) days prior written
notice of such reduction to Registered Holders of the Warrants and, provided further that if any reduction is also being made to the warrant price of (i) the 5,738,000 warrants issued to LMFAO Sponsor, LLC, a Florida limited liability company
(the “Private Placement Warrants”), (ii) the 10,350,000 warrants issued to public investors in the initial public offering of units of the Company’s equity securities (the “Public Warrants”)
and/or (iii) any other warrants issued or to be issued in connection with the Transaction or in the period of ten (10) Business Days following the Transaction Closing (the “Other Warrants”), any such reduction shall
be proportionally the same as the reduction to the Warrant Price, as applicable. “Business Day” means any day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal
business. 
 3.2 Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise
Period”) commencing on the date of the Transaction Closing and terminating at 5:00 p.m., New York City time on the earlier to occur of: (x) the date that is five (5) years after the date of the Transaction Closing; or
(y) the liquidation of the Company (the Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection
3.3.2 below with respect to an effective registration statement. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided, that the Company shall provide at least twenty
(20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among each of (i) the Warrants, (ii) the Private Placement
Warrants, (iii) the Public Warrants, and (iv) the Other Warrants. 
 3.3 Exercise of Warrants. 

3.3.1 Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof
by delivering to the Warrant Agent at its corporate trust department: (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Book-Entry Warrant Certificate, the Warrants to be exercised (the
“Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from time to time; (ii) an
election to purchase (“Election to Purchase”) shares of 

  
 2 

 
Common Stock pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of the Definitive Warrant Certificate or, in the case of a Book-Entry
Warrant Certificate, properly delivered by the Participant in accordance with the Depositary’s procedures; and (iii) payment in full of the Warrant Price with lawful money of the United States for each full share of Common Stock as to
which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock and the issuance of such shares of Common Stock, as follows: 

(a) by certified check payable to the order of the Warrant Agent or by wire transfer; or 

(b) as provided in Section 7.4 hereof. 

3.3.2 Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the
funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full shares of
Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for
the number of shares of Common Stock as to which such Warrant shall not have been exercised. If fewer than all the Warrants evidenced by a Book-Entry Warrant Certificate are exercised, a notation shall be made to the records maintained by the
Depositary, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise. Notwithstanding the foregoing, the Company shall not be obligated to deliver any
shares of Common Stock pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise, other than pursuant to Section 7.4, unless a registration statement under the Securities Act with
respect to the shares of Common Stock underlying the Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4. No Warrant shall be
exercisable and the Company shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the Common Stock issuable upon such Warrant exercise has been registered, qualified or deemed to be exempt from registration or
qualification under the securities laws of the state of residence of the Registered Holder of the Warrants, except pursuant to Section 7.4. In the event that the conditions in the two immediately preceding sentences are not
satisfied with respect to a Warrant, the holder of such Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless. In no event will the Company be required to net cash settle the Warrant exercise.
If, by reason of any exercise of Warrants on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share of Common Stock, the Company shall round down to
the nearest whole number, the number of shares of Common Stock to be issued to such holder. 
 3.3.3 Valid Issuance. All shares of
Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and non-assessable. 

3.3.4 Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is
issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made,
irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent
are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of business on the next succeeding date on which the share transfer books or book-entry system are open. 

3.3.5 Maximum Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the
provisions contained in this subsection 3.3.5; provided, however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall
not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the
Warrant Agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify)(the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after
giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of
the Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock that would be issuable upon: (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by
such person and its affiliates; and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible
notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership
shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in determining the number of outstanding shares of Common Stock,
the holder may rely on the number of outstanding shares 

  
 3 

 
of Common Stock as reflected in: (1) the Company’s most recent annual report on Form 10-K, quarterly report on Form 10-Q, current report on Form 8-K or other public filing with the Commission as the case may be; (2) a more recent public announcement by the Company; or (3) any
other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business
Days, confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of equity
securities of the Company by the holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the holder of a Warrant may from time to time increase or
decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is
delivered to the Company. 
 4. Adjustments. 

4.1 Stock Dividends. 

4.1.1 Split-Ups. If after the date hereof, and subject to the provisions of
Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or
other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to
such increase in the outstanding shares of Common Stock. A rights offering to holders of the Common Stock entitling holders to purchase shares of Common Stock at a price less than the “Fair Market Value” (as defined below) shall be deemed
a stock dividend of a number of shares of Common Stock equal to the product of: (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are
convertible into or exercisable for the Common Stock) and (ii) one (1) minus the quotient of: (x) the price per share of Common Stock paid in such rights offering, divided by (y) the Fair Market Value. For purposes of this
subsection 4.1.1: (i) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, there shall be taken into account any consideration received for such rights,
as well as any additional amount payable upon exercise or conversion; and (ii) “Fair Market Value” means the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading
day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights. 

4.1.2 Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or
make a distribution in cash, securities or other assets to the holders of the Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock into which the Warrants are convertible), other than:
(a) as described in subsection 4.1.1 above; or (b) Ordinary Cash Dividends (as defined below) (any such non-excluded event being referred to herein as an “Extraordinary
Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Company’s board of
directors (the “Board”), in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash
Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4
and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) does not exceed $0.50. 

4.2 Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the
number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination,
reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock. 

4.3 Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is
adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction:
(x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment; and (y) the denominator of which shall be the number of shares of Common Stock so
purchasable immediately thereafter. 
 4.4 Replacement of Securities upon Reorganization, etc. In case of any reclassification or
reorganization of the outstanding shares of Common Stock (other than a change under subsections 4.1.1 or 4.1.2 or Section 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in
the case of any merger or consolidation of the Company with or into another entity or conversion of the Company as another entity (other than a consolidation or merger in which the Company is the continuing

  
 4 

 
corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another entity of the assets
or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the exercise of the Warrants
and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash)
receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s)
immediately prior to such event (the “Alternative Issuance” ); provided, however, that in connection with the closing of any such consolidation, merger, sale or conveyance, the successor or purchasing entity
shall execute an amendment hereto with the Warrant Agent providing for delivery of such Alternative Issuance; provided, further, that: (i) if the holders of the Common Stock were entitled to exercise a right of election as to the
kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall
be deemed to be the weighted average of the kind and amount received per share by the holders of the Common Stock in such consolidation or merger that affirmatively make such election; and (ii) if a tender, exchange or redemption offer shall
have been made to and accepted by the holders of the Common Stock under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor rule)) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule
12b-2 under the Exchange Act (or any successor rule)) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act (or any successor rule)) more than 50% of the outstanding shares of Common Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of
cash, securities or other property to which such holder would actually have been entitled as a stockholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the
Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for
in this Section 4; provided, further, that if less than 70% of the consideration receivable by the holders of the Common Stock in the applicable event is payable in the form of common stock in the successor
entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted
immediately following such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current Report on
Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) (but in no event less than zero) equal to the difference of: (i) the Warrant Price in effect prior to such
reduction; minus (ii) (A) the Per Share Consideration (as defined below); minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately
prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets (“Bloomberg”). For purposes of calculating such amount: (1) the price
of each share of Common Stock shall be the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event; (2) the assumed
volatility shall be the 90 day volatility obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event; and (3) the assumed risk-free interest rate shall
correspond to the U.S. Treasury rate for a period equal to the remaining term of the Warrant. “Per Share Consideration” means: (i) if the consideration paid to holders of the Common Stock consists exclusively of cash,
the amount of such cash per share of Common Stock; and (ii) in all other cases, the amount of cash per share of Common Stock, if any, plus the volume weighted average price of the Common Stock as reported during the ten (10) trading day
period ending on the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in shares of Common Stock covered by subsection 4.1.1, then such adjustment shall be made
pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications,
reorganizations, mergers or consolidations, sales or other transfers. In no event will the Warrant Price be reduced to less than the par value per share issuable upon exercise of the Warrant. 

4.5 Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares of Common Stock issuable upon
exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares of Common Stock
purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2,
4.3 or 4.4, the Company shall give written notice of the occurrence of such event to each Registered Holder, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event.
Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event. 
 4.6 No Fractional
Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares of Common Stock upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this
Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the
number of shares of Common Stock to be issued to such holder. 

  
 5 

 4.7 Form of Warrant. The form of Warrant need not be changed because of any
adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this
Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant
thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed. 

4.8 Other Events. In case any event shall occur affecting the Company as to which none of the provisions of preceding subsections of
this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to: (i) avoid an adverse impact on the Warrants; and (ii) effectuate the intent and purpose of
this Section 4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking or other appraisal firm of recognized national standing, which shall give its opinion as to
whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine that an adjustment is necessary, the terms of such
adjustment, provided, however, that under no circumstances shall the Warrants be adjusted pursuant to this Section 4.8 as a result of any issuance of securities in connection with the Transaction. The Company shall adjust
the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion. 
 4.9 No Adjustment. For
the avoidance of doubt, no adjustment shall be made to the terms of the Warrants solely as a result of an adjustment to the conversion ratio of the Company’s Class B common stock (the “Class B
Common Stock”) into shares of Common Stock or the conversion of the shares of Class B Common Stock into shares of Common Stock, in each case, pursuant to the Company’s Charter, as amended from time to time. 

5. Transfer and Exchange of Warrants. 

5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the
Warrant Register, upon surrender of such Warrant for transfer, in the case of certificated Warrants, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new
Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the
Company from time to time upon request. 
 5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent,
together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate
number of Warrants; provided, however, that except as otherwise provided herein or in any Book-Entry Warrant Certificate or Definitive Warrant Certificate, each Book-Entry Warrant Certificate and Definitive Warrant Certificate may be
transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor depository, or to a nominee of a successor depository; provided further, however, that in the event that a Warrant
surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may
be made and indicating whether the new Warrants must also bear a restrictive legend. 
 5.3 Fractional Warrants. The Warrant Agent
shall not be required to effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant. 

5.4 Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants. 

5.5 Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed
on behalf of the Company for such purpose. 
 6. [Intentionally Left Blank] 

7. Other Provisions Relating to Rights of Holders of Warrants. 

7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of
directors of the Company or any other matter. 
  

  
 6 

 7.2 Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost,
stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new
Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or
destroyed Warrant shall be at any time enforceable by anyone. 
 7.3 Reservation of Common Stock. The Company shall at all times
reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement. 

7.4 Registration of Common Stock; Cashless Exercise at Company’s Option. 

7.4.1 Registration of the Common Stock. Section 7 (Registration of Subscriber Securities) of the Subscription Agreement as it
applies to the Subscriber Shares (as defined in the Subscription Agreement) will apply, mutatis mutandis, to the Warrants, as if it had been fully set forth herein. If the Registration Statement (as defined in the Subscription Agreement) has
not been declared effective by the earlier of (i) the 45th calendar day (or 75th calendar day if the Commission notifies the Company that it will “review” the registration statement) following the Transaction Closing and (ii) the
second (2nd) Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review, holders of the
Warrants shall have the right, during the period beginning on the 46th calendar day (or 76th calendar day if the Commission notifies the Company that it will “review” the registration
statement) after the Transaction Closing and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall fail to have maintained an effective registration statement covering
the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act (or any successor rule) or
another exemption) for that number of shares of Common Stock equal to the quotient obtained by dividing: (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the Warrant Price and
the “Fair Market Value” (as defined below), by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume weighted average price of the Common Stock as reported
during the ten (10) trading day period ending on the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice of
cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion
of counsel for the Company (which shall be an outside law firm with securities law experience) stating that: (i) the exercise of the Warrants on a cashless basis in accordance with this subsection 7.4.1 is not required to be registered
under the Securities Act; and (ii) the shares of Common Stock issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the
Securities Act (or any successor statute)) of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of any doubt, unless and until all of the Warrants have
been exercised or have expired, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1. 

7.4.2 Cashless Exercise at Company’s Option. If the Common Stock is at the time of any exercise of a Warrant not listed on a
national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act (or any successor statute), the Company may, at its option: (i) require holders of Warrants
who exercise Warrants to exercise such Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor statute) as described in subsection 7.4.1; and (ii) in the event the Company
so elects, the Company shall not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this
Agreement to the contrary. If the Company does not elect at the time of exercise to require a holder of Warrants who exercises Warrants to exercise such Warrants on a “cashless basis,” it agrees to use its best efforts to register or
qualify for sale the Common Stock issuable upon exercise of the Warrant under the blue sky laws of the state of residence of the exercising Warrant holder to the extent an exemption is not available. 

8. Concerning the Warrant Agent and Other Matters. 

8.1 Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the
Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common Stock. 

  
 7 

 8.2 Resignation, Consolidation, or Merger of Warrant Agent. 

8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and
be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by
the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for
the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good
standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After
appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any
further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority,
powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in
and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations. 
 8.2.2 Notice
of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the Common Stock not later than the effective date of any
such appointment. 
 8.2.3 Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or
with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act. 

8.3 Fees and Expenses of Warrant Agent. 

8.3.1 Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent
hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all reasonable and documented third party expenditures that the Warrant Agent may reasonably incur in the execution of its duties
hereunder. 
 8.3.2 Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed,
executed, acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement. 

8.4 Liability of Warrant Agent. 

8.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it
necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed
to be conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer, President, Executive Vice President, Vice President, Secretary or Chairman of the Board of the Company and delivered to the
Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement. 

8.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The
Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except
as a result of the Warrant Agent’s gross negligence, willful misconduct or bad faith. 
 8.4.3 Exclusions. The Warrant Agent
shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company
of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner,
method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation
of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock shall, when issued, be valid and fully paid and non-assessable.

 8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by
this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all
monies received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of the Warrants. 
 8.6 Waiver.
The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain
Investment Management Trust Agreement, dated as of the date hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the
Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account.

CUSIP _____ 
 Warrant
Certificate 
 This Warrant Certificate certifies that _______, or registered assigns, is the registered holder of
warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase shares of Class A common stock, $0.0001 par value per share (“Common Stock”), of LMF
Acquisition Opportunities, Inc., a Delaware corporation (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that
number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable
in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of
the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Each Warrant is initially exercisable for one fully paid and non-assessable share of Common Stock. No
fractional shares will be issued upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a share of Common Stock, the Company will, upon exercise, round down to the nearest
whole number the number of shares of Common Stock to be issued to the Warrant holder. The number of shares of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events set forth in the Warrant
Agreement. 
 The initial Exercise Price per share of Common Stock for any Warrant is equal to $11.50 per share. The Exercise Price is
subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 
 Subject to the conditions set forth in
the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. 

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions
shall for all purposes have the same effect as though fully set forth at this place. 
 This Warrant Certificate shall not be valid unless
countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. 
 This Warrant Certificate shall be governed by and
construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

[Reverse] 
 The Warrants
evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to be issued pursuant to a Warrant Agreement dated as of
[    ], 2022 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agent”),
which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent,
the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by the
holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this
Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement
(or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall
be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised. 

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised, other than pursuant to
Section 7.4 of the Warrant Agreement, unless at the time of exercise: (i) a registration statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act; and (ii) a prospectus thereunder
relating to the shares of Common Stock is current, except through “cashless exercise” as provided for in the Warrant Agreement. 

The Warrant Agreement provides that upon the occurrence of certain events the number of shares of Common Stock issuable upon exercise of the
Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in a share of Common Stock, the Company shall, upon
exercise, round down to the nearest whole number of shares of Common Stock to be issued to the holder of the Warrant. 
 Warrant
Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to
the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 

Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge
except for any tax or other governmental charge imposed in connection therewith. 
 The Company and the Warrant Agent may deem and treat the
Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof,
and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.

 Exhibit 10.27 

EMPLOYMENT AGREEMENT 

This EMPLOYMENT AGREEMENT (the “Agreement”) is made as of May 18, 2022 (the “Effective Date”) by and between
SeaStar Medical, Inc. (the “Company”), and Kevin Chung (“Executive”). 
 NOW, THEREFORE, in consideration of the
promises and mutual covenants contained herein, the parties agree as follows: 
 1.    Employment
Period. Executive’s employment with the Company pursuant to this Agreement shall be “at will,” and either the Company or Executive may terminate the employment relationship at any time in accordance with the provisions
of Paragraph 7. The period during which Executive is in fact employed by the Company pursuant to this Agreement shall constitute the “Employment Period” hereunder. Executive’s commencement of employment hereunder shall be July 1,
2022 (the “Employment Commencement Date”). 
 2.    Duties and Responsibilities. 

A.    During the Employment Period, Executive shall serve as the Company’s Chief Medical Officer (“CMO”),
and will work out of his home office in Virginia, subject to reasonable business travel, and shall report to the Company’s Chief Executive Officer (“CEO”). Executive agrees to perform in good faith and to the best of his ability all
services that may be required of Executive hereunder and to be available to render such services at all reasonable times and places in accordance with such directions and requests as may be made from time to time by the Company or Board of Directors
of the Company (the “Board”). 
 B.    Executive is expected and agrees to devote his full working time and
attention to the business of the Company, and will not render services to any other business without the prior approval of the Company, directly or indirectly, engage or participate in any business that is competitive in any manner with the business
of the Company. To maintain Executive’s medical license, Executive will work in hospital setting up to four days on average per month. Notwithstanding the foregoing, to continue to build executive presence, Executive may participate in up to
four advisory or foundation boards at one time. Executive also may invest in up to one percent (1%) of the outstanding securities of any publicly-held corporation without approval of the Company. Moreover, in the sole discretion of, and upon
approval from, the CEO, Executive may participate in other board or advisory positions that do not in any way negatively impact or conflict with the Company or Executive’s employment with the Company. 

C.    Executive understands and agrees that he must fully comply with the Company’s standard operating policies,
procedures, and practices that are from time to time in effect during the term of his employment. 

3.    Compensation. 

A.    During the Employment Period, Executive shall receive an annual gross base salary in the amount of Three Hundred
Fifty Thousand Dollars ($350,000), to be paid in monthly installments accordance with the Company’s normal payroll procedures, less all applicable withholdings and deductions (“Base Salary”). 

 B.    The Company shall pay Executive a
one-time signing bonus in the amount of Twenty-Five Thousand Dollars ($25,000) (the “Signing Bonus”), less all applicable withholdings and deductions, payable to Executive on July 31, 2022,
provided Executive is employed on the payment date. 
 C.    During the Employment Period, Executive will be eligible to
receive an annual discretionary bonus of up to a maximum amount of 40% of the Base Salary, with the actual amount, if any, to be determined in the sole discretion of the Company, based on a combination of factors including Company and individual
performance. The Bonus, if awarded, shall be paid to Executive no later than March 15 of the year following the year to which the Bonus relates (the “Bonus Payment Date”), provided Executive is employed by the Company on the Bonus
Payment Date. If Executive is not employed by the Company on the Bonus Payment Date, Executive shall not receive any Bonus. 

D.    The Company shall deduct and withhold from any compensation payable to Executive any and all applicable federal,
state, and local income and employment withholding taxes and any other amounts required to be deducted or withheld by the Company under applicable statutes, regulations, ordinances, or orders governing or requiring the withholding or deduction of
amounts otherwise payable as compensation or wages. 
 4.    Equity. 

A.    On or following commencement of Executive’s employment and subject to approval of the Board, the Company will
grant Executive an option under the Company’s Equity incentive plan then in effect (the “Plan”) to purchase up to [TBD] shares of the Company’s Common Stock (the “Option”), which is a number of shares equal to 1% of the
outstanding capital stock of the Company. The Option will have an exercise price equal to the fair market value of the Company’s common stock on the date of grant, be immediately exercisable, subject to the right of repurchase of unvested
shares, and will vest over four (4) years in forty-eight (48) equal monthly installments commencing on the one-month anniversary of the Employment Commencement Date. Vesting shall cease upon
Executive’s cessation of employment with the Company and will be subject to the terms and conditions of the Plan and the written Stock Option Agreement governing the Option. Notwithstanding the foregoing (i) in the event of certain
separations from service from the Company, the vesting of the Option will be accelerated to the extent set forth in Paragraph 8 below; and (ii) Executive shall have up to twelve (12) months following any termination of employment to
exercise any then-vested options to purchase Company Common Stock (and understands and assumes the burden for any modified treatment thereunder associated with the extended exercise period). 

5.    Benefits; Reimbursement. 

A.    Health Insurance. During the Employment Period, Executive shall be eligible to participate in
all employee benefits and benefit plans generally made available to the Company’s employees from time-to-time, including, but not limited to, medical, dental,
vision and long-term disability insurance benefits and arrangements, subject to the terms, conditions and relevant qualification criteria for such benefits and benefit plans. The Company, in its discretion, may change from time-to-time the employee benefits and benefit plans it generally makes available to its employees.

 B.    Expense Reimbursement. During the Employment
Period, Executive shall be entitled to reimbursement for all reasonable and necessary expenses incurred by Executive associated with the conduct of the Company’s business in accordance with the Company’s policies. Such reimbursements shall
be subject to the Company’s then-existing policies and procedures for reimbursement of business expenses, but in any event shall include submission of written requests for reimbursement within thirty (30) days of incurring the expense,
accompanied by vouchers, receipts or other details of such expenses in the form required by the Company, sufficient to substantiate a deduction for such business expenses under all applicable rules and regulations of federal and state taxing
authorities. If such expense qualifies for reimbursement, then the Company will reimburse Executive for that expense in accordance with existing expense reimbursement policies and practices. 

C.    Vacation, Sick, and Holiday Pay. During the Employment Period, Executive shall be entitled to
earn or receive vacation, sick, and holiday pay pursuant to the terms of the Company’s generally applicable employee policies, as may exist from time to time. 

6.    Proprietary Information and Inventions Agreement. As a condition of employment and the
benefits provided by this Agreement, Executive is required to timely execute and return the Company’s form of Proprietary Information and Inventions Agreement, attached hereto as Exhibit A (the “PIIA”). Executive
shall at all times remain subject to the terms and conditions of such PIIA, and nothing in this Agreement shall supersede, modify, or affect Executive’s obligations, duties, and responsibilities thereunder. 

7.    Termination of Employment. Executive’s employment pursuant to this Agreement is
“at will” and may be terminated by either party at any time, with or without cause, in accordance with the following provisions: 

A.    Upon cessation of Executive’s employment for any reason, Executive, or his estate if applicable, shall be paid
any unpaid Base Salary earned under Paragraph 3 for services rendered through the date of such termination. 

B.    Executive may voluntarily separate from his employment under this Agreement at any time and for any reasons, but is
requested to give the Company at least thirty (30) days prior written notice of such resignation. 
 C.    The
Company may terminate Executive’s employment with or without Cause under this Agreement at any time by providing notice of such termination to Executive. Such termination shall be effective immediately upon Executive’s receipt of such
notice, unless otherwise indicated by the notice. 
 8.    Severance Benefits 

A.    Resignation, Termination for Cause, or Death. If Executive resigns, is terminated for Cause (as defined
below), or dies, then he (or his estate, as applicable) shall only be entitled to payment of his Base Salary payable through the date of termination, but shall not otherwise be entitled to any severance or separation pay from the Company. 

B.    Termination Without Cause. If the Company terminates Executive’s employment without Cause (as defined
below) then, subject to Executive timely executing, returning, and not revoking a separation agreement and general release of claims acceptable to the 

  
 3 

 
Company in its discretion (“Separation Agreement”), the Company will pay Executive as severance in an amount equivalent to twelve (12) months of Executive’s Base Salary in
effect on the termination date, and payable in equal installments as salary continuation payments for a 12-month period following the termination date (“Severance Payment”), in accordance with the
Company’s normal payroll dates and practices, the first installment of which shall be made on the Company’s first regular payroll period following the sixtieth (60th) day after the termination date (and will include any Severance Payment
installment(s) that would have otherwise been paid during the period following the termination date through the date of the first Severance Payment installment); provided that, Executive has timely executed and delivered the Separation Agreement and
the Separation Agreement has become irrevocable by its terms as of such date. The Severance Payment shall be in lieu of any other severance benefits under any Company plan, program or policy, and Executive waives his rights, if any, to have such
payment taken into account in computing any other vested benefits payable to or on behalf of Executive, by the Company, if any. 

C.    Termination Without Cause Following Change in Control. If the Company terminates Executive’s employment
without Cause (as defined below) within twelve (12) months following a Change of Control (as defined below), then, in addition to the severance payment set forth above, and similarly subject to Executive timely executing, returning, and not
revoking the Separation Agreement, then 100% of any remaining balance of any unvested Shares shall immediately vest. 

(1)    For purposes of this Agreement, “Cause” means, in the Company’s reasonable good faith belief that
one of the following have occurred: 
 (i)    Executive’s commission of any act of fraud, embezzlement,
dishonesty, or sexual harassment; 
 (ii)    Executive’s refusal or failure to comply in any material respect with
any written policies or procedures of the Company, any parent of the Company, or the Board (including, without limitation, the Company’s anti-discrimination and harassment policies and the Company’s drug and alcohol policy); 

(iii)    any unauthorized use or disclosure by Executive of confidential information or trade secrets of the Company (or
any parent or subsidiary of the Company); or 
 (iv)    any other gross negligence or misconduct by Executive adversely
affecting the business or affairs of the Company (or any parent or subsidiary of the Company) in a material manner. 

(2)    For purposes of this Agreement, “Change of Control” means a change in ownership or control of the
Company effected through any of the following transactions: 
 (i)    a merger, consolidation or other reorganization
approved by the Company’s stockholders, unless securities representing fifty percent (50%) or more of the total combined voting power of the voting securities of the successor corporation are immediately thereafter beneficially owned, directly
or indirectly and in substantially the same proportion, by the persons who beneficially owned the Company’s outstanding voting securities immediately prior to such transaction; 

  
 4 

 (ii)    a sale, transfer, or other disposition of all or substantially
all of the Company’s assets; 
 (iii)    the closing of any transaction or series of related transactions pursuant
to which any person or any group of persons comprising a “group” within the meaning of Rule 13d-5(b)(1) of the Securities Exchange Act of 1934, as amended (the “1934 Act”) (other than the
Company or a person that, prior to such transaction or series of related transactions, directly or indirectly controls, is controlled by or is under common control with, the Company) acquires directly or indirectly (whether as a result of a single
acquisition or by reason of one or more acquisitions within the twelve (12)-month period ending with the most recent acquisition) beneficial ownership (within the meaning of Rule 13d-3 of the 1934 Act) of
securities possessing (or convertible into or exercisable for securities possessing) fifty percent (50%) or more of the total combined voting power of the Company’s securities (as measured in terms of the power to vote with respect to the
election of Board members) outstanding immediately after the consummation of such transaction or series of related transactions, whether such transaction involves a direct issuance from the Company or the acquisition of outstanding securities held
by one or more of the Company’s existing stockholders; or 
 (iv)    a change in the composition of the Board over
a period of twelve (12) consecutive months or less such that a majority of the Board members ceases, by reason of one or more contested elections for Board membership, to be comprised of individuals who either (A) have been Board members
continuously since the beginning of such period or (B) have been elected or nominated for election as Board members during such period by at least a majority of the Board members described in clause (A) who were still in office at the time
the Board approved such election or nomination. 
 9.    Benefit Limit. The benefit
limitations of this Paragraph shall be applicable in the event Executive receives any benefits under this Agreement which are deemed to constitute parachute payments under Code Section 280G. In the event that any payments to which Executive
becomes entitled in accordance with the provisions of this Agreement would otherwise constitute a parachute payment under Code Section 280G, then such payments will be subject to reduction to the extent necessary to assure that Executive
receives only the greater of (i) the amount of those payments which would not constitute such a parachute payment or (ii) the amount which yields Executive the greatest after-tax amount of benefits
after taking into account any excise tax imposed on the payments provided to Executive under this Agreement (or on any other benefits to which Executive may become entitled in connection with any change in control or ownership of the Company or the
subsequent termination of his employment with the Company) under Code Section 4999. 
 10.    Delayed
Commencement of Benefits. Notwithstanding any provision to the contrary in this Agreement, no payments or benefits that are subject to the restrictions of Code Section 409A to which Executive becomes entitled under this Agreement
shall be made or paid to Executive prior to the earlier of (i) the expiration of the six (6)-month period measured from the date of his separation from service with the Company or (ii) the date of his death, if Executive is
deemed at the time of such separation from service a “key employee” within the meaning of that term under Code Section 416(i) and such delayed commencement is otherwise required in order to avoid a prohibited distribution under Code
Section 409A(a)(2). Upon the expiration of the applicable Code Section 409A(a)(2) deferral period, all payments deferred pursuant to this Paragraph shall be paid in a lump sum to Executive, and any remaining payments due under this
Agreement shall be paid in accordance with the normal payment dates specified for them herein. 

  
 5 

 11.    Compliance with Section 409A. It is the intent
of the Company and Executive that the provisions of this Agreement comply with all applicable requirements of Code Section 409A. Accordingly, to the extent any provisions of this Agreement would otherwise contravene one or more requirements or
limitations of Code Section 409A, then the Company and Executive shall, within the remedial amendment period provided under the Treasury Regulations issued under Code Section 409A, effect through mutual agreement the appropriate amendments to
those provisions which are necessary in order to bring the provisions of this Agreement into compliance with Section 409A. If any payment under this Agreement is subject to Code Section 409A, (i) distributions shall only be made in a
manner and upon an event permitted under Code Section 409A, (ii) payments to be made upon a termination of employment or service shall only be made upon a “separation from service” under Code Section 409A, (iii) each
payment shall be treated as a separate payment for purposes of Code Section 409A, and (iv) if any payment is subject to the execution of a Separation Agreement, in no event shall the timing of Executive’s execution of the Separation
Agreement result in Executive designating, directly or indirectly, the calendar year of payment, and if such a payment that is subject to execution of the Separation Agreement could be made in more than one taxable year, payment shall be made in the
later taxable year. 
 12.    Cessation of Benefits. In the event of a breach by Executive
of any of his obligations of this Agreement or under the PIIA, he shall cease to be entitled to any further benefits under this Agreement. In no event shall Executive be entitled to any severance benefits under this Agreement if (i) his
employment ceases by reason of a termination for Cause, or (ii) he voluntarily resigns from employment with the Company. 

13.    Successors and Assigns. This Agreement and all rights hereunder are personal to
Executive and may not be transferred or assigned by Executive at any time. The Company may assign its rights, together with its obligations hereunder, to any parent, subsidiary, affiliate, or successor, or in connection with any sale, transfer, or
other disposition of all or substantially all of its business and assets, provided, however, that any such assignee assumes the Company’s obligations hereunder. 
  

14.    Notices. 

A.    Any and all notices, demands or other communications required or desired to be given hereunder by any party shall be
in writing and shall be validly given or made to another party if delivered either personally or if deposited in the United States mail, certified or registered, postage prepaid, return receipt requested. If such notice, demand, or other
communication shall be delivered personally, then such notice shall be conclusively deemed given at the time of such personal delivery. 

B.    If such notice, demand, or other communication is given by mail, such notice shall be conclusively deemed given
forty-eight (48) hours after deposit in the United States mail addressed to the party to whom such notice, demand or other communication is to be given as hereinafter set forth: 

To the Company: 

SeaStar Medical, Inc.

Denver, CO 80516 
 Attn: Chief
Executive Officer

 To Executive: 

Kevin Chung, MD 
 6910 Strata
Street 
 Mclean, VA 22101 

(or such personal address as the Company may have on file for Executive at the time of notice.) 

C.    Any party hereto may change its address for the purpose of receiving notices, demands and other communications as
herein provided by a written notice given in the manner aforesaid to the other party hereto. 

15.    General Creditor Status. The benefits to which Executive may become entitled under this
Agreement shall be paid, when due, from the Company’s general assets, and no trust fund, escrow arrangement or other segregated account shall be established as a funding vehicle for such payments. Accordingly, Executive’s right (or the
right of the executors or administrators of Executive’s estate) to receive such benefits shall at all times be that of a general creditor of the Company and shall have no priority over the claims of other general creditors. 

16.    Governing Documents. This Agreement, together with (i) any equity award
agreements, and (ii) the PIIA, shall constitute the entire agreement and understanding of the Company and Executive with respect to the terms and conditions of Executive’s employment with the Company and the eligibility for any potential
severance payments and consulting payments following separation from employment with the Company, and this Agreement shall supersede all prior and contemporaneous written or verbal agreements and understandings between Executive and the Company
relating to such subject matter. This Agreement, including but not limited to the at-will nature of the employment relationship as reflected herein, may only be amended by written instrument signed by
Executive and the CEO. 
 17.    Governing Law. The provisions of Agreement shall be
construed and interpreted under the laws of the State of Virginia applicable to agreements executed and wholly performed within the State of Virginia. If any provision of this Agreement as applied to any party or to any circumstance should be
adjudged by a court of competent jurisdiction to be void or unenforceable for any reason, the invalidity of that provision shall in no way affect (to the maximum extent permissible by law) the application of such provision under circumstances
different from those adjudicated by the court, the application of any other provision of this Agreement, or the enforceability or invalidity of this Agreement as a whole. Should any provision of this Agreement become or be deemed invalid, illegal or
unenforceable in any jurisdiction by reason of the scope, extent or duration of its coverage, then such provision shall be deemed amended to the extent necessary to conform to applicable law so as to be valid and enforceable or, if such provision
cannot be so amended without materially altering the intention of the parties, then such provision will be stricken, and the remainder of this Agreement shall continue in full force and effect.

 18.    Arbitration. 

A.    Except as provided herein and the PIIA, each party hereto agrees that any and all disputes which arise out of or
relate to Executive’s employment, the termination of Executive’s employment, or the terms of this Agreement shall be resolved through final and binding arbitration. Such arbitration shall be in lieu of any trial before a judge and/or jury,
and Executive and the Company expressly waive all rights to have such disputes resolved via trial before a judge and/or jury. Such disputes shall include, without limitation, claims for breach of contract or of the covenant of good faith and fair
dealing, claims of discrimination, claims under any federal, state, or local law or regulation now in existence or hereinafter enacted and as amended from time to time concerning in any way Executive’s employment with the Company or its
termination. The only claims not covered by this Employment Agreement to arbitrate disputes, which shall instead be resolved pursuant to applicable law, are: (i) claims for benefits under the unemployment insurance benefits; (ii) claims
for workers’ compensation benefits under any of the Company’s workers’ compensation insurance policy or fund; (iii) claims under the National Labor Relations Act; and (iv) claims that may not be arbitrated as a matter of
law. 
 B.    Arbitration will be conducted in Virginia. Arbitration shall be conducted in accordance with the Federal
Arbitration Act (“FAA”) and the National Rules for the Resolution of Employment Disputes of the American Arbitration Association (“AAA Rules” available at www.adr.org) or any other discovery required by applicable law in
arbitration proceedings, including, but not limited to, discovery available under the applicable state and/or federal arbitration statutes. Also, to the extent that any of the AAA Rules or anything in this arbitration section conflicts with any
arbitration procedures required by applicable law, the arbitration procedures required by applicable law shall govern. 

C.    During the course of arbitration, the Company will bear the cost of (i) the arbitrator’s fee, and
(ii) any other expense or cost Executive would not be required to bear if Executive were free to bring the dispute or claim in court. Each party shall bear such party’s own attorneys’ fees incurred in connection with the arbitration.
The arbitrator will not have authority to award attorneys’ fees unless a statute or contract at issue in the dispute authorizes the award of attorneys’ fees to the prevailing party. In such case, the arbitrator shall have the authority to
make an award of attorneys’ fees as required or permitted by the applicable statute or contract. 
 D.    The
arbitrator shall issue a written award that sets forth the essential findings of fact and conclusions of law on which the award is based. The arbitrator shall have the authority to award any relief authorized by law in connection with the asserted
claims or disputes. The arbitrator’s award shall be subject to correction, confirmation, or vacation, as provided by applicable law setting forth the standard of judicial review of arbitration awards. Judgment upon the arbitrator’s award
may be entered in any court having jurisdiction thereof. 
 E.    This arbitration provision does not prohibit Executive
from pursuing an administrative claim with a local, state, or federal administrative agency such as the Equal Employment Opportunity Commission, but this arbitration agreement does prohibit Executive from seeking or pursuing court action regarding
any such claim. 
 19.    Counterparts. This Agreement may be executed in more than one
counterpart, each of which shall be deemed an original, but all of which together shall constitute but one and the same instrument. 

  
 8 

 20.    Construction. The language of this
Agreement shall be construed as to its fair meaning, and not strictly for or against either party. Any rule of construction that any ambiguities in a contract shall be construed against the drafter of a contract shall not apply. 

21.    Indemnification. Executive will be provided indemnification to the maximum extent
permitted by the Company’s and its subsidiaries’ and affiliates’ Articles of Incorporation or Bylaws, but on terms no less favorable than provided to any other Company executive officer or director and subject to the terms of any
separate written indemnification agreement. 
 IN WITNESS WHEREOF, the parties have executed this Employment Agreement as of the day and year written
above.
