Patient is a 84 years old female patient of, DO with history of chronic hypoxic respiratory failure, COPD, CAD, HTN, HLD, and depression presented to Hospital with shortness of breath, cough.  Admitted and being managed for acute on chronic hypoxic respiratory failure, pneumonia COVID COPD exacerbation. Not much significant success with weaning off supplemental oxygen complicated by patient's inability to expel sputum.   Acute on chronic hypoxic respiratory failure, COVID-19 infection COPD/Asthma with mild acute exacerbation Pulmonary HTN, presumed Group 3 Bacterial pneumonia Presented with 1 week history of non-productive cough and worsening SOB. Patient fully vaccinated and 1 booster  Afebrile, HR 77, RR 15, BP 125/71, satting >94% on 2L NC (2L qHS at home) Initial CBC w slight leukocytosis to 11.76. Hgb 10.5. ProBNP 3.2K CXR: No vascular congestion or consolidation PFT 2016: FEV/FVC 0.54, FEV1 39% (22% reversible), TLC 201% Echo 3/2023 with EF 72%, TRVmax 3.59 m/s (RVSP 62) VBG showed pH of 7.25 with PCO2 66.2 Chest x-ray done showed left infrahilar streaky opacity likely represent focal pneumonia and/or aspiration.  CT of the chest without contrast showed development of a peripheral airspace consolidation left lower lobe and to a lesser extent peripheral IVs in the dependent right lower lobe which may indicate aspiration and/or pneumonia.  There is also numerous scattered bilateral multilobar tree-in-bud nodular opacity indicating underlying small airway inflammatory changes. Switch IV Solu-Medrol to Decadron IV if in case COVID infection contributed to lung finding.
