Cheyne Stokes Respiration?

Cheyne Stokes Respiration?
            [attachment=30564][attachment=30564][attachment=30564]I've been on my cpap for a couple of months.  I changed to a nasal mask and wore it last night.  It showed I have numberous apneas but one that caught my eye that I have never had was a Cheyne Stokes Respiration.  This scared me.  What does that mean.

Here are my charts:
Thanks

RE: Cheyne Stokes Respiration?
Unfortunately, Resmed labels variable breathing as CSR. It rarely actually meets the clinical definition of CSR and is instead an oscillation of tidal volume that falls into a pattern. You need to zoom in on the shaded event to actually see what is going on. When CSR is flagged for this short period of time, and is bracketed by CA events, it's a good bet that your respiration increased and decreased several times in a feedback loop resulting from being near your "apneic threshold". CSR is frequently associated with heart failure, and it is extremely unlikely you would be unaware of CSR if it was actually a problem.

Thanks for your reply.  I zoomed in as request.  I hope this is helpful. I just saw that and I scared me.;(

RE: Cheyne Stokes Respiration?
Common periodic breathing resulting from a feedback loop at the apneic threshold. Often starts with an apnea followed by hyperventilation which lowers CO2 (hypocapnea). That reduces respiratory drive and sometimes results in hypopnea or central apnea which increases CO2 (hypercapnea) and increases respiratory drive. It is a feedback loop, so it repeats until it works itself out your system and respiration normalizes. This article is extreme overkill, but covers the subject https://physoc.onlinelibrary.wiley.com/d...004.028985

Ok. So you think this is not CVR but variable breathing? Anything I should change? I'm trying to sleep on my side but found myself on my back which I know is worse for apneas.
Thanks

RE: Cheyne Stokes Respiration?
The periodic breathing and apneic threshold arises out of pressure support or EPR. You can probably reduce the extent of that by reducing the EPR setting.

RE: Cheyne Stokes Respiration?
Ok I'll change the EPR from 2 to 1

Could you omment on the zoomed in graphs. Do they tell you anything that says it's probably not CSR. I see my pulmonogist on Monday for cpap follow up.
Thanks

I'm not a chart reading guru, but if you had CSR you'd have pretty major health indications and a cardiac doctor that would tell you that you have a heart condition after a series of tests like echocardiogram and nuclear stress tests and all kinds of other things. As I understand it, you'd not have to guess. It's highly likely the misflag issue. Certainly you can mention it to the doc just to be sure.

RE: Cheyne Stokes Respiration?
I'll just add, if you complain about CSR with a pulmonologist based on 9-minutes of variable breathing, you will be totally discredited as someone self-diagnosing on the internet. I'm sure the doctor will have more comforting words, but, let me assure you CSR looks a lot different and lasts a lot longer. This problem will not resurface when you reduce EPR to 1. Prove me wrong.
