I am a new CPAP user (2 weeks) Checking my results on line I was surprised to see that on two of the nights my events per hour were quite high (24 per hour) even though I was wearing the full face mask and the fit was good. Is this normal or should I be concerned that something else is causing the apnea events?

When you quit breathing 24 times per hour, this is called moderate sleep apnea and indicates therapy is NOT repeat NOT working as it should. Go over your results with whoever prescribed your machine's set up and discuss as the prescription is obviously not keeping your airway open. When you stop breathing your blood oxygen level can drop dangerously low and organs such as heart and brain will be damaged over time. I strongly suggest your consult with your medical professional!

You say this happened on 2 nights out of a fortnight. What is your AHI the rest of the time? This certainly warrants investigation. It may be that you were on your back for those 2 nights and this made your OSA worse. If this is the case you either have to prevent yourself from lying on your back or increase your pressure to handle sleeping in your back. An AHI of 24 is certainly quite high.

Thank you for the responses. Excluding the two nights with 25 events, I have averaged 6.95 events per hour. (over a two week period.) Not sure whether I was sleeping on my back those two nights. That would be unusual for me. I will follow up with the equipment provider to see if they have any experience random spikes like this. Like "wiredgeorge" I am concerned if the therapy isn't working as designed. I have no intention of undergoing this torture if I don't get results! So, I will be paying close attention to this issue.

The just under 7 episodes per hour is under the "dangerous" threshold, but that still seems kind of high to me. Is your CPAP set to auto adjust pressure according to your prescription, or can you adjust the pressure yourself? If so, you probably need your pressure increased.

Honestly, in my humble opinion, CPAP therapy should treat one's issue with SA in a way in which a person should be able to sleep either on one's back, side, or however they feel comfortable, without apnea increase over a dangerous level. To me, the therapy is not working if you can't sleep on your back.
