CPAP and "complex sleep apnea"

Found the text below on the Mayo Clinic wet site (https://www.mayoclinic.org/diseases-con ... c-20352109). I imagine this subject shows up here now and then like a comet in orbit, but since some of us have been here less than a year, I thought it's worth raising again:

"Complex sleep apnea. Some people with obstructive sleep apnea develop central sleep apnea while using continuous positive airway pressure (CPAP) for their sleep apnea treatment. This condition is known as complex sleep apnea because it's a combination of obstructive and central sleep apneas."

I don't know what the timeframe might be but, personally, I have been having a bunch of CAs showing up on my daily stats the past few weeks, so naturally got my attention. Anyone aware of any clinical trials on this question?

Cheers,

MC

I thought All Sleep Apnea was pretty complex, Not breathing seems complex to me. I don't treat labels, I treat my Sleep Apnea with my XPAP. It's worked for 13 years, looking for 13 more after that we"ll see. Jim

The timeframe is important.

But what is considered a reasonable timeframe? 13 years of CPAP bliss? 13 weeks? Research apparently indicates that, for some, CPAP usage can boost CAs over time while in other cases, CA prevalence fades. I'm just wondering if anyone knows of actual research. If not, no worries. I'll hunt it down myself.

Thanks,

MC

The timeframe of your ca's are they spread throughout the night? are they clustered at the beginning and end (ie, transitional/sleep wake junk).

Pressure dependent CAs tend to get *better* over time, not worse, as the body gets used to the pressure.

I think I got lucky, My machine doesn't measure CA's False or Real, just A's & H's, so I don't have to worry about them, I just treat the AHI and sleep away, breathing all night. Worry isn't good for your health, too many thing that really matter to deal with.

Going from almost dead to badly damaged and 13 years more worn out, is a win, win in my case. Jim

Actually it does flag CAs/Centrals but just dumps them in the OA or hyponea basket. This is what I was told about those older Respironics machines from one of the software developers at Respironics.
If your AHI is low...you don't have a problem with centrals.

Good to know, I was feeling left out, if my AHI goes over 2.0 I feel it. Usually it's a shaving problem or mask moving around, I have to keep leaks under 38 LPM usually 2 weeks ago I had to go back to my FF Mask nose too stuffy forced too much mouth breathing.

I'm almost ready to dig my APAP out for a while, it's not been on for 7 years, need to test it. Jim

Complex sleep apnea describes a form of sleep-disordered breathing in which repeated central apneas. I think you can contact sleep-disordered specialist, he gives you the better solution to your problem.

This is about as good a summary as I've seen. https://myapnea.org/blog/complex-sleep-apnea

Thanks, Brook. Very good article.
