He presents from rehab facility where he has been for PT/OT after a recent back surgery in September. Pt endorses SOB, cough productive of sputum, and decreased oxygen saturation. Pt states he has felt unwell for 4 days. I spoke on the phone with a nurse at his facility who states his oxygen saturation dropped as low as 50% at one point and otherwise had been in the 80s occasionally. He was Covid positive on 11/2 and started on decadron daily at that time. His oxygen had been increased as high as 5L at the facility. Pt denies f/c/s. He tells me he has been crying a lot and feels very emotional. Denies chest pain, abdominal pain, N/V, dysuria, diarrhea. States he has had a good appetite and denies swallowing difficulty. Denies feeling wheezy. Denies orthopnea.    Pt arrives to ER tachycardic, tachypnea, 71% on room air, placed on HFNC 55L O2 95% FiO2. vPh 7.44. glucose 258. CXR with cardiomegaly, small left pleural effusion, bilateral pulmonary infiltrates predominating in left mid and lower lung, can be seen with COVID-19 pneumonia, pulmonary edema not excluded. Received albuterol and duoneb treatments. Admit to INPT for acute on chronic hypoxic respiratory failure in the setting of Covid pneumonia. ER also ordered 6 mg decadron. CMP then results with potassium of 6.3, and AKI with Cr 1.5 (0.7), hemolysis noted so will repeat. Repeat BMP shows improved potassium down to 5.4. calcium gluconate was ordered by ER staff as well as lokelma. A fluid bolus was ordered by ER staff but this is discontinued as there is concern some pulmonary edema could be worsening his respiratory status.
