Notes from 9.20.21: ASSESSMENT / PLAN:   Acute on chronic hypoxic respiratory failure Severe COVID-19 pneumonia s/p vaccination COPD exacerbation - Continue HFNC and titrate to maintain saturations of 90-94% - Continue Decadron; s/p Remdesivir - Maintain euvolemia and diurese prn -Antitussives prn, encourage IS use and prone  - Continue duonebs q 6h prn - Mucinex  - Dulera and spiriva and Singulair  **DDimer was increasing; no PE noted, small acute thrombus in the cephalic vein that does not require full dose anticoagulation. CTA does show PA dilation; likely c/w PAH.
