Hey, my dad is 65 and he had COVID pneumonia back in April with a pretty high HRCT score of 1225. He was discharged at the end of April and was keeping his SPO2 levels up at 98 without any extra oxygen. But since mid-July, his SPO2 has been hanging around 95 to 96, and it only hits 98 in the morning. Should I be worried that the infection might be coming back? Hes doing pranayama and using that 3-ball lung exercise tool every morning for 40 minutes.
