Is there any harm in using oxygen 24/7 at 3 litre from a concentrator. I am told it will make lungs to work less and they will retain CO2. I have end stage bronchiectasis with multiple cystic cavity on all my lobes. I am 44 and my doctor advised me a transplant which at present is not possible due my very low body weight of 35 kg for a 6 feet man.
Please advice me friends. I feel better on oxygen than bipap which is very difficult to fit and also dries out my sinuses.
Thanks a lot
