helloi have a neighbour who is about 81 years old.  he is very much overweight and has just been diagnosed as having lung fibrosis.  he has shortness of breath and years ago, has had a heart by-pass.  should he be on oxygen apart from drugs to cure him?
Respected user, Welcome to Chat Doctor.come have evaluated your query thoroughly.* The need of oxygen is dependent upon the capacity of lungs to oxygenate the body with purified oxygen.* If the existent lung fibrosis, body oxygen saturation is maintained no need of oxygen but if the existing lung fibrosis is not able to do such, then patient definitely require oxygen. Hope this will help you. Regards.
