I posted here recently and was offered some very helpful support, I wish I could return the favor.
Does anybody have experience with using an mask instead of a nasal cannula. I've noticed that my mother can maintain a much better saturation using a mask over a cannula(the cannula supplying the o2) than with the cannula alone at the same o2 rate. The fully thing is, it's any mask, not just a rebreather(for instance a mask from nebulizer not plugged in). I have no idea why this is the case, even her doctor doesn't have a clue but says to do what works.
Anyway, thanks again for any input.
