Hello Hope, welcome to healingwell. Glad that your mom is doing so well now.
My husband started oxygen about 3 weeks before he died. It didn't help his liver enough to extend his life very long. It helped him breathe easier yes. And yes I know it is good for all a person's organs not to be oxygen deprived.
I've have never heard anything about oxygen being able to reverse cirrohsis. The liver is an amazing organ. The liver can reguvenate itself if there is minimal damage. But I am under the understanding that once there's cirrohsis, there's no reversing the cirrotic liver damage itself. The healthy part of the liver can reguvenate but not the cirrotic part.
Anyone, correct me if I am wrong please.
(Connie please excuse my spelling....I am not at home and can't find spell check on this computer.)
Take care........
