I'm really worried about my dad. He was discharged from the hospital about 10 days ago and he's still on 2 liters of oxygen because his left lung got pretty damaged from COVID. I'm wondering how long he might need to stay on oxygen. If we take it off for about 30 minutes, his saturation levels drop to 80-85, should we be concerned? How long do you think it'll take for him to recover?
he might be having chronic obstructive pulmonary disorder, there's no particular time for him to quit oxygen. he might need it for years
