I've seen a few times lately on this board where the mask is described as "air tight." Bob is right. It's a non-rebreather mask that you need, Dave. A non-rebreather mask has a small patch of tiny holes on the side of the mask so that your exhalation can escape the mask allowing you to inhale just the O2.
