Multiple chest x-rays showing patchy perihilar left-sided airspace disease. 2. CT angiogram of the chest showing bilateral patchy airspace opacities.  HOSPITAL COURSE: A 75-year-old male, primary care patient of Dr., presented to the emergency room with shortness of breath.  He actually states he was feeling fine and did not want to come to the ER, but his son insisted and dropped him off.  In the ER, he was COVID positive with infiltrates on x-ray and was 89% saturating on room air.  He was therefore admitted, was started on supplemental oxygen.  He was not given any specific treatments and monitored and did not have any worsening of his oxygenation.  He was saturating 93% to 94% on room air at the time of discharge.  With ambulation his oxygen saturation went down to 84% and so he did qualify for home oxygen temporarily.  It is felt to be stable for discharge home on this.  Dexamethasone was withheld due to non-severe disease and his already profound hyperglycemia from diabetes.  DISCHARGE DISPOSITION: CONDITION:  Stable.
