As I stated, I am not a professional, I was just posting a possible hypothesis. I understand that CPAP does not "breath" for a person, but was postulating that forced air into the lung, thereby "filling" the lungs with air keeps the O2 levels "up" in the lungs and because of this, the diaphragm might not pull as hard leading to volumization issues. I am not sure of the exact numbers, but it is my understanding that we can pull in 2500-300 cc's of air under normal circumstances, but decreased volume, either through less "effort" on the diaphram's part or inability to expand due to mid-section or chest weight issues (gravity, laying on the back, etc..) could lead to less voumization of the lungs. It is my contention that lowered volumization of the lungs can lead to saturation levels falling below optimum levels <90%. Again, this is an intellectual workout and I CERTAINLY don't have all the answers.
