He desaturated at home and to 77% and responded well in the emergency department with 2 L nasal cannula saturating in the mid 90s.  He was given a dose of 6 mid Decadron and maintained on oxygen supplementation.  By the morning patient was off of oxygen and saturating in the low to mid 90s.  On ambulation patient desaturated to around 89% but then recovered quickly.  Pulmonary rehab evaluated him and he did not need home oxygen.  At this point given the patient was not requiring supplemental oxygen and had significant clinical improvement he was stable for discharge.  He discharged with 9 additional days of Decadron.  He was told to follow-up with his primary care provider and get a repeat BMP within 1 week.

ASSESSMENT / PLAN: 81 y.o. male with a past medical history of AS s/p TAVR 2020, complete heart block with pacemaker, CAD s/p 6 vessel CABG 2009, paroxysmal Atrial fib on Eliquis, dilated cardiomyopathy, T2DM, OSA, CKD3b, HTN who presented with cough and hypoxia and was found to be COVID positive. Acute hypoxic respiratory failure COVID. Two weeks upper respiratory infection symptoms with positive COVID test today.  Vaccinated x4. Hypoxic at home to the 70s, hypoxic on arrival today 89% improved with 2 L nasal cannula.  CXR with bilateral patchy opacities. Was prescribed Paxlovid by his PCP and he has taken 1 dose of this. Less likely heart failure, appears euvolemic on exam, and was never short of breath.  Unlikely this is pulmonary embolus, is on Eliquis and no chest pain.  Plan to discuss with him in the morning of starting remdesivir verses continuing his Paxlovid which was started outpatient and brought with him. Although no published clinical trials for inpatient Paxlovid use (only current indication for outpatient to prevent hospitalization and death after positive test), could potentially be as used as an antiviral now as we would remdesivir. As of now however, there are no completed Clinical trials of using Paxlovid in hypoxic patients, or those being treated in the inpatient setting. Anticipate will recommend to not continue taking inpatient. - Oxygen support wean as tolerated - Respiratory isolation - Decadron 6 mg for 10 days started 05/28- no need for additional DVT prophylaxis, is on Eliquis; T2DM   On 48 units Lantus at home.

Last echo EF 52%.  Currently appears euvolemic on exam, not in heart failure exacerbation. Will continue home meds. - Coreg, Lisinopril, HCTZ - Statin (ASA dc'd by EP 01/2022)- Eliquis 5mg BID- OSA   - Home CPAP- CKD3b   To baseline creatinine 1.3.

Two weeks ago he started developing upper respiratory infection symptoms of cough and congestion.  Cough is mildly productive of green/yellow sputum.  No hemoptysis.  He had a known COVID exposure of his daughter at this time.  He is vaccinated x4 for COVID.  Symptoms did not improve and acutely worsened 2 days ago.  He used his home pulse ox to check his oxygen which she reports was in 70s, and was encouraged by his daughter to present to the ER.  Denies chest pain, dyspnea.  No lower extremity swelling, lightheadedness, palpitations. On arrival to the ED, he was afebrile, slightly hypertensive systolic 150, with O2 saturations 93% on room air.  Remainder of vitals were normal and stable.  Oxygenation increased to 98% with 2 L nasal cannula. Laboratory testing significant for creatinine of 1.57 - baseline around 1.3, mild anemia hemoglobin of 12.0.  Remainder of complete blood count and CMP normal.  COVID testing was positive. EKG normal sinus rhythm showing known left bundle branch block. Chest x-ray shows bilateral patchy airspace opacities worse on the right. He was given a dose of Decadron 6 mg admitted to Medicine.
