Hello. I am new to the forum. I was diagnosed in 2008 and have been on CPAP ever since. Recently I got a new machine, a ResMed Airsense10. My previous machine did not have a readout that I could see in the morning, but my doctor had told me I was at about 3-5 events per hour. On the AS10 - my report shows anywhere from 0 to .5 per hour most nights and up to 3.5 some nights. What I don't understand is this - when I see .5 events per hour, does that truly mean that I am averaging one half of an event per hour (or 1 event per two hours on average)? Thanks for your input.
