Anyone else have apneas that last this long?

[Susanm]

I finally got a copy of my sleep report Saturday evening, and I noticed that at least one of my apneas was 81 seconds long! Almost a minute and a half with no oxygen! Is that insane or what? I also get no deep sleep. Even with the cpap at my titration study, I got 0 minutes of stage 3 & 4 sleep. My MSLT showed an average sleep latency of less that 5 minutes. Does this sound like maybe something besides OSA is messing up my sleep? I never knew sleep could be so complicated ....

You may have other things disturbing your sleep, but we KNOW that one thing is, and that's sleep apnea. I know this isn't the answer you're looking for, but get that piece we know is causing you problems under treatment, and then we find out if anything else is going on.

There's no real way to know what else is going on, especially if you have something like PLMD going on, as your OSA can disturb your sleep enough that the other thing(s) don't show up. Once we have that out of the way, it'll be much easier to see what else is going on.

Yes, I had one that lasted that long and my O2 sat dropped to 70%. Scares one enough to want to be compliant with therapy!!

Hi and welcome to CPAPLAND. I wouldn't worry too much yet about even with the cpap during titration you didn't see great results. It's not unusual to have difficulty with being hooked up to a strange contraption, not to mention the wires. The real test will be how well you sleep once your treatment adjustment phase levels off.

The only thing that jumped out at me on your results was the mixed apneas, which is something I've not seen on any of my 7 sleep studies thru the years. I'm sure some others who have dealt with this will jump in on that topic. There's a lot of knowledge to be gained so that you can get the best from your treatment. For starters, I would ask the sleep doc to explain the mixed apneas and how that may affect your treatment, if at all.

Best wishes as you sort thru all this and settle into a routine.

My AHI was 82 and o2 dropped to 58%..

Yes, it definitely makes me want to be compliant. After a lifetime of low blood pressure, my diastolic went waay up earlier this year, and my legs and feet started swelling to the point of making it hard to walk. Since cpap (and walking 20 minutes a day) my pressure is back down to a normal 100/60. And I don't have to go potty half a dozen times every night .

Now if it would only make me feel better, instead of worse ...

On my first sleep study, I had an apnea that lasted 3 minutes and 42 seconds, but I have mixed apnea, and that particular one was a central. Dont remember what my sat was though. Good Times!!
