Sonia,
Just about anything can effect your sat, the things you have listed will all effect ventilation(getting air in and out) so in essence yes....It will effect oxygenation. There actually is big technical answer with but trying to keep it simple, several factors effect how well oxygen binds to hemoglobin, temperature and carbon dioxide are both major contributers to the oxygen/hemoglobin dissassocaition curve. Is that what you were looking for, or did I just stray way off in left field?</end quote></div>
Thanks, Luke... yes, that does help! I'm just kinda curious if this sort of "number" is as "tempermental" as our FEV1 on any given day/moment... If so, it isn't really as reliable as I had thought?
Thanks for the info.! It is interesting the "weight" we put into such "tests" to determine our health status... i.e. FEV1 is XYZ so you must go into the hospital no matter how you feel... O2 is XYZ so you must wear oxygen no matter how you feel, etc....
