>>"The pressure is relatively static to "inflate" >>your throat tissues"

That's precisely why we do have a noticeable increase in air volume, some of us more than others. As you well point out the CPAP air pressure used to "inflate" or stint the throat tissue is static or constant. However, that collapsing throat tissue is nowhere near as static or constant---rather is is **extremely** variable in how severely and infrequently it closes. So when the throat tissue does not need this added air pressure to stint the airway open, we still get it on fixed-pressure CPAP. End result for the vast majority of moments throughout the night? Added air volume---especially for people with low-to-moderate AHI's! We are all taught the static model of apneic airway closures and offsetting potential energy to offset it (by the way of fixed air pressure)----and it is wrong, wrong, wrong. It should be presented as a dynamic model, which is the reality of the situation in terms of physics.
