Thanks BryanC, that was very helpful!

When I look at the "Events" tab at the "OA", is that how many times I quit breathing?

Ok, here is another question for any one: How can you view how many times you quit breathing (or have apeana's) with this Philips Respironics System One without the software? My doctor has turned the pressure down due to me swallowing the air, and I would like to know how many times I quit breathing...
