Sleep doc's views of APAP machines

That said, I do wake up once or twice a night, generally at one of the peaks in pressure., so there does seem to be a trade-off at work, at least in my case.

You could try lowering the upper range of your pressure a bit and see what it does to your AHI.

What's your pressure range now? I see you don't list it in your profile.

It's normally from about 7 to 12 but once or twice a week goes as high as 16 (on a couple of occasions over the past few months it's got as high as 20).

What range should I aim for with these stats?

What he meant by range is what is the machine set to, not what it gets to.

Sorry, I'm not very knowledgable about all this. The machine is set from 4 to 20.

When set to that range, we call that 'wide open'. Some argue it is not a good thing to have it that way, others say it doesn't matter.

This may be why your data says it goes up and down in such peaks and drops.

You may want to narrow that range a bit. You say it goes as low as 7 and as high as 16. You may want to then set that as the range, give it two weeks, and look at the data again. You'll probably be able to drop that higher number down some more.

All of these words, phrases, and alphabet soup can get to be confusing! You'll figure out the lingo soon enough.

There's nothing wrong with being at high pressure all the time unless you have gas, central apneas, can't sleep due to the pressure, or leaks. It's a question of what works for you.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

Many thanks for the very helpful suggestion and the understanding.

I didn't realise that. Grateful for the reassuring info.

I thought you were concerned that something is waking you up during the night. It could be the high pressure.

Yes, that is what I'm concerned about. I will try lowering the max pressure and see if that makes any difference (both to the waking up and my ahi).
