Would hyperbarics chambers oxygenize in a different way than ventilators, or is it the same thing? I declined admission 2yrs back when I had RSV (b) even though I felt a bit desperate for oxygen (and really sucked it down in the ER.) I was at 85% and left at 95%. I was surprised they don't send you home with prescribed oxygen. (Been wondering about those little canisters of oxygen they sell in catalogs, and those oxygen bars lol.) At the time, as my lungs filled, I kept fantasizing about the dental hygienist's suction tool!
