Dear team my dad admitted in ICU due to breathing problems with pneumonia, he is in ICU from 11th October to till date, now doctors are telling his lungs not functioning only 40% left, whenever I see him in ICU he looks active and respond for all medical. But once he shifted to normal ward he becomes breathless and drozyness also, his ABG varying from 50 to 60, BPM is 118 to 125, O2 82 without oxygen. Now doctor's telling he should be on BIPAP and O2 even after shifting home also, I'm worried about his health, I took second opinion with pulmonary specialist and he said his lungs are ok good,
