My father had covid during the peak time. On 12th April, he was tested positive. He was hospitalized as he had developed pneumonia, the oxygen level was 91 and Lungs CT score was 12/24. Oxygen was given for a few days (2 to 3 hours per day) to keep the level. Heart Rate was normal too.
No history of BP/
sugar/ hypertension.
Please suggest what all follow up check up should he undergo to check the normal body functions.
