I wouldn't think the APAP is waking you up to control the event. Your pressure looks pretty constant, even at the times in question. I think the APAP wasn't fast enough or didn't try to fix your pressure. Remember that the algorithm is not so lighting quick. I think these events flew under the radar for some reason.

Which means that maybe you and your doctor should discuss an increase of pressure. Seems as if your current pressure settings are not stopping enough of the apnea/hypopnea events --- could be increased to remove more events.

Just my $0.02.

Bee,
Instead of the APAP waking you, it might have been the apneas waking you. One was 16 seconds and ther other a 10 second one.

I tend to agree with Mike, maybe an slight increase in pressure may correct the situation.

i agree it was probably the apneas.

So should I ask the doc to set my pressure at a constant, put it on the CPAP and take it off the APAP, say at a setting of12 ? My autoset is at 8-12. Most nights the top pressure is 1.6-11.6

JNK, Thanks so much for your opinion. This does represent a typical night. I WILL sleep well! Smiles.

It looks to me like you are getting good therapy. But trying straight CPAP is something most of us end up doing eventually, just to see if sleep seems more restful.

I, like the others, seriously doubt it is anything about the way the machine is set up that is waking you. My guess is that those two apneas were centrals that occurred as you shifted sleep states or that they represent your switching from asleep-breathing to awake-breathing, or something. It takes a long time for some of our brains to learn not to wake up after they get all happy with themselves for making it through a few complete sleep cycles. Brains are funny that way. I laugh at what mine does all the time.

Looking at your charts, I would probably either try sleeping at straight 10 with no EPR or at 12 with an EPR of 2, and see what my numbers did.

But again, having two apneas in a night is no biggie, waking up now and then just happens, and those hypopneas are ResMed-measured hypopneas, so they are no big deal. You can always try to do better for the fun of it, but you aren't doing bad at all now, in my opinion, if those charts represent an average night for you.

Sleep well!

It is very common to wake up at the end of a sleep cycle, or at least enter back into stage one where we might be at least aware of our surroundings. base your judgement of your therapy on how you feel, then look at your AHI. if your AI is is low, and your HI is under 5 i would not worry.

THANKS for the info and support. b

I agree bee need not worry. Just curious: is it typical to have more apneas when our brains shift gears into a different sleep cycle?
