Warnings and Cautions

Warnings&
Cautions

For veterinary use only.
Personnel operating this Laboratory Animal Anesthesia System must be
thoroughly familiar with the instruction manual and equipment operation
prior to use with patients.
Tampering with the anesthesia system components by unauthorized personnel voids all warranties and specifications. The prevention of tampering with the anesthesia system is the sole responsibility of the user orowner. VetEquip assumes no liability for any malfunction, failure, damage
or loss to either equipment or life.
(Model 901809) Failure to open the APL (evacuation) valve with a patient
attached to the absorber assembly could result in the death of the patient.
Before using the anesthesia system, check that it is set up properly andensure all connections and settings are correct. For the Model 901809,
perform the “10 Second Leak Test” as outlined in the “Pre-operative Check”
section of this manual to verify the breathing circuit is leak-free.
Always adhere to proper Diameter Index Safety System (D.I.S.S.) hoseconnections. Failure to comply will void your warranty and could compromise patient safety.
If the oxygen flush button does not immediately return to the off position
after being released or if the flow of oxygen does not immediately stop
flowing from the common outlet after the oxygen flush button is released,
remove the machine from service. The valve must be repaired by VetEquip
or a VetEquip authorized service facility before using the machine.
When turning off flowmeters, it is only necessary to turn the flow control
knob clockwise until the ball float reaches the bottom of the tube. Excessive tightening will damage the valve seat, resulting in a leak requiring
replacement of the valve.

Theory of Operation

Theory ofOperation

An inhalation anesthesia system is designed to do the following:
1. Change a liquid anesthetic agent into a vapor.
2. Deliver that vapor to the patient in a precisely measurable amount.
3. Sustain the patient by delivering a metabolic gas in addition to the anesthetic
vapor.
4. Capture all waste gas.
5. Channel the waste gas to an evacuation system such as anactivated charcoal canister or a scavenging interface.

VetEquip, Inc. - Pleasanton, California USA - 800-466-6463
Rev. 0703– 13 –

Operational Flowchart

1. Oxygen flows from a pressurized tank that may be located on the anesthesia
machine, in the room with the anesthesia machine, or in a remote area with theoxygen being piped through the walls.

Operational
Flowchart

2. A regulator is attached to the supply tank and reduces the pressure of theoxygen from as high as 2200 PSI down to a useable 55 PSI.
3. The oxygen flow reaches the anesthesia machine through the DISS connection
and is then plumbed into two channels:a. One channel goes to the oxygen flowmeter. By using the flow control knobon the flowmeter, you further reduce the 55 PSI to a flow measured in liters
per minute (LPM).
b. The other channel goes to the oxygen flush valve. In the normal (closed)
position, the flush valve has no flow through it. When the flush button ispushed, the oxygen flows directly into the patient circuit at a rate of approximately 15-35 LPM. This oxygen does not pass through the vaporizer.
4. The oxygen flow from the flowmeter is delivered to the inlet of the vaporizer. If
the vaporizer is in the “OFF” position, the oxygen bypasses the vaporizer without
picking up any anesthetic agent. If the vaporizer dial is turned to any position
other than “OFF”, a precise concentration of vaporized anesthetic agent isdelivered through the outlet of the vaporizer to the patient circuit. The vaporizer
dial is adjusted by the operator and determines the amount of anesthetic agent
vapor that will be added to the oxygen flow. The amount is measured as apercentage of the total flow and can be varied from 0-5%.
5. Lines from the vaporizer and the oxygen flush valve merge through the common
outlet and into the dual procedure circuit.
6. Once the gas enters the dual procedure circuit, it is bifurcated by a Y-fitting into
two branches. A stopcock within each branch of the circuit provides independent
control of each branch.
a. One branch goes to the induction chamber. When the stopcock to the
induction chamber is open, the gases flow into the chamber through the feedtube. Turbulence circulates the anesthetic gases throughout the chamber
until it exits through the evacuation port on the induction chamber, flowing
passively through flexible evacuation tubing (FlexHose) and into a charcoal
filter.
b. The other channel goes to the patient breathing circuit. When the stopcock
to the patient circuit is open, the gases flow to the nose cone of the breathing
circuit. The gases then continue through the down-tube of the breathing
circuit and into a second charcoal filter.

Pre-Operative Check & Operation

For veterinary use only.
Personnel operating this Laboratory Animal Anesthesia System must
be thoroughly familiar with the instruction manual and equipment
operation prior to use with patients.

Pre-Operative
Check andOperation

Tampering with the anesthesia system components by unauthorized
personnel voids all warranties and specifications. The prevention oftampering with the anesthesia system is the sole responsibility of theuser or owner. VetEquip assumes no liability for any malfunction,
failure, damage or loss to either equipment or life.
Always adhere to proper Diameter Index Safety System (D.I.S.S.)
hose connections. Failure to comply will void your warranty andcould compromise patient safety.

1. Ensure gas supply line for each gas is attached to appropriate D.I.S.S. inlet onback of the flowmeter(s). Connect gas supply hose(s) to in-house supply asnecessary.
2. Ensure gas supply is turned on and is of sufficient quantity for the procedure(s).
When turning off flowmeters, it is only necessary to turn the control
knob clockwise until the ball float reaches the bottom of the tube. Excessive over-tightening will eventually lead to damaging of the valve
seat, resulting in a leak at this point and necessitating replacement.

3. Test oxygen flowmeter for full range of operation by turning the control valve knob
counter-clockwise to open and clockwise to close valve. Close valve when test iscomplete.
4. Test oxygen flush valve for performance by depressing and holding the button for
3 seconds. Oxygen should flush rapidly out of the common outlet. When theoxygen flush button is released, it should immediately return to the off position
and the flow should immediately stop.
If the oxygen flush button does not immediately return to the OFF
position after being released, or if the flow of oxygen does not
immediately stop flowing from the common outlet after the oxygen
flush button is released, remove the machine from service. Have thevalve repaired by calling VetEquip or a VetEquip-authorized service
facility before using this machine.
Before using the anesthesia system; check that it is set up properly,
ensure all connections and settings are correct. For the Model
901809, perform the “10 Second Leak Test” as outlined in the “Preoperative Check” section of this manual to verify the breathing circuit
is leak-free.

5. Fill the vaporizer with the appropriate anesthetic agent. Refer to vaporizer
instruction manual for complete instructions.

VetEquip, Inc. - Pleasanton, California USA - 800-466-6463
Rev. 0703– 16 –

Use Protocol

Every facility should have in place an inhalation anesthesia protocol / SOP.
The following is an outline from which you can begin to create your own.
If you need assistance writing your protocol, please call us at 800-466-6463.

Use
Protocol1. After checking to ensure your oxygen supply tank(s) is/are open and that you
have sufficient gas pressure in the line(s) from the tank(s), assemble your systemand check all connections for possible oxygen leaks.
Oxygen tank to regulator (If oxygen is supplied from a free-standing tank)
If any hissing is detected, check the condition of the gasket between the tankand regulator (E-cylinder only) and tighten the regulator onto the tank.
Machine to dual delivery system
This common outlet port is a friction-fit connection. Ensure connections madeare leak-free.
Dual delivery system to nose cone and chamber connection
These are friction-fit connections. Ensure connections made are leak-free.
Breathing elbow down tube and chamber outlet port to charcoal filters
Connect tubing to charcoal filter to create a leak-free connection. For proper
operation, the charcoal filter must be oriented vertically, ensuring the exit holes
in the bottom are not obstructed. Filter canister holders are provided for thispurpose.
WARNING

Standing filters directly on a surface will impede the airflow
out the bottom of canister, rendering the filter useless andcausing back pressure in the breathing circuit.

2. If required, fill the vaporizer with the appropriate liquid agent, according to
instructions in the vaporizer manual.
3. Open the stopcock in the chamber tubing line.
4. Close the stopcock in the nose cone line.
5. Turn the oxygen flowmeter to at least one (1) liter per minute (lpm).
6. Place animal #1 in the induction chamber and secure the lid.
NOTE
You may place as many animals in the chamber as will fit comfortably.
WARNING
The chamber is airtight. If the oxygen flowmeter on the machine isturned off, there will be NO AIRFLOW into the chamber.
NEVER leave animals in the chamber without an oxygen flow.

Rev. 0703– 17 –

Use Protocol

Use
Protocol7. Turn the vaporizer dial to 2-2½%. Animal #1 should begin to lose consciousness
within 2 minutes.
8. When Animal #1 has no response to rocking/jiggling the chamber, push theoxygen flush button for 20 to 30 seconds (for 2 liter chamber) to evacuate allanesthesia-saturated gas from the chamber.
NOTE
The brief oxygen flush evacuations of the chamber should not awaken
already anesthetized animals.
If the stopcock to the nose cone/mask is open when the oxygen flush button
is depressed, the resulting oxygen pressure through the nose cone may pushthat animal’s nose out of the nose cone. Always close the stopcock to thenose cone mask before using oxygen flush.
9. Open the stopcock in the nose cone line.
10. Immediately close the stopcock in the chamber tubing line. Open the chamberand remove Animal #1.
11. Place Animal #1’s nose in the nose cone.
12. Place Animal #2 in the chamber and open the stopcock in the chamber tubingline.
13. When the procedure on Animal #1 is complete, close the stopcock in the nose
cone line and place Animal #1 in a recovery unit. That animal will begin toawaken in approximately 2 minutes.
14. Repeat steps 8 through 12 with Animal #2, and all remaining models, until allprocedures have been completed.
15. Turn the vaporizer dial to the “OFF” position.
16. Turn off the oxygen flowmeter.
17. If a freestanding oxygen tank is used, turn off the oxygen at the tank.
18. Clean and sanitize the chamber and nose cone/mask as outlined in yourprocedure area cleaning protocols.
