Cheyne Stokes Respiration Question

Cheyne Stokes Respiration Question
I've seen a number of posts on the topic and did some research online. CSR looks pretty nasty but it doesn't seem ResMed's data can confirm it's actually happening. 

My OSCAR results last night look like an image I found here showing what CSR looks like so I'm back to ask if I should be concerned.

Thanks for this wonderful community!

Admitted I don't know enough about it, but if you had the condition your heart health would already be in question as I understand it. So is your heart health OK?

RE: Cheyne Stokes Respiration Question
1st ResMed calls any periodic breathing CSR.
Your pattern is CSR and to be clear we don't like it.
I know nothing of your medical history so I'll suggest you advise, and print a copy of this chart for your doctors, that is your PCP, cardiac, pulmonologist, and sleep doc.

As you noted CSR may be related to a number of other conditions, the most notable is CHF. You likely already know if you have that. This is about 30 minutes I
And is the lower limit where some docs get concerned enough to look for it.

You are using EPR =3. This in a few 'lucky' individuals can cause what you see so I'd like you to reduce it to 1.

This pattern frequently occurs in xPAP users because you breathing has improved with cpap use.
Your breathing is driven by a complex based on many parameters with the main drive being to expell excess CO2 from your system. As the CO2 levels in your blood drop your body sees less need to breathe until you hit your apneic threshold and stop breathing with a central event (CA) . With the stoppage your CO2 increases and your breaths get deeper and then your starts to tapper off Untill you once again hit your apneic threshold.

In your case EPR is likely to be contributing to this thus please

Set EPR=1

Repost tomorrow and we can check again.

RE: Cheyne Stokes Respiration Question
I meant to ask if you have any heart or breathing issues other than Apnea

Brain injuries, strokes, siezures, meds especially pain killers, in addition to some heart conditions can contribute to central apneas, so do any of these apply?

RE: Cheyne Stokes Respiration Question
Thank you!

No diagnosis of CHF and this pattern is not a real regular occurrence. In the 26 days I've had the new machine it's happened 5 times.

I'll change the EPR to 1 and continue to monitor.

RE: Cheyne Stokes Respiration Question
I have exactly the same type of event happening since I started CPAP treatment in Sept 2020. I get them about 50% of sleeps in a month. I have a history of frequent waking and which leads me to believe that I have had these CSB/CSA events starting 2 years prior to starting on a CPAP. I didn't have them on the home test so I have been treated as having just OSA and when I eventually had a full polysomnogram I didn't have the event then either. I have done tons of research and there are various reasons why these events can occur. The Sleep clinic that tested me and sold me the CPAP eventually referred me to a sleep doctor but they have never supplied him with the overnight data including the graphs so it has been very frustrating. I am sending him my own downloads from OSCAR so he can see what is going on and I hope to get some help next week when I speak to him. I would strongly advise you to discuss this with your doctor. They are very nasty and I am finding it more amd more difficult to cope with the extreme fatigue that they have caused.

During my Covid-episode I had a couple of nights with periods of CSR. No heart problems anyway. So spontaneous phases of CSR might indicate a disease.

RE: Cheyne Stokes Respiration Question
Innisfree, please start your own therapy thread and post charts.Always post a full night for context and evaluation. And additional charts you choose to illustrate what you have questions on.

Especially where CA is involved, a copy of your redacted sleep studies as we want to see what, if any was present before cpap and what shows initially with cpap use.
