Chayne Stokes Respiration

[gdroman]

Hi gdroman,
WELCOME! to the forum.!
I don't know the answer to your question but hang in there, I know there is someone who will be able to help you.
Much success to you with your CPAP therapy.

I'm learning already. I'm trying to get a sense of what type of apneas caused my diagnosis. I really appreciate the support.

I'm seeking to learn more about Chayne Stokes Respiration (CSR) episodes. Other than the technical definition and connection to conditions like congestive heart failure, I'm not finding very much. Like, for sleep apnea patients, how often (how many times a night) or frequently (hour, night, week) CSR episodes can be a cause of serious concern? How long in duration these episodes are significantly serious (seconds, minutes)?

I would love to read thoughts and experiences from patients and professionals on this matter. Thank you!

There are a number of us on this forum with Central Apnea/periodic breathing. Try a google search for "Apnea Board Central Apnea" and also look a Search on the Apnea board for "Cheyne Stokes". You should also post more context which might include your statistics CAs Hypopneas etc. I assume that your using a "CPAP" machine and have found CAs that look like Cheyne Stokes Respiration (CSR). Did you have these and or Hypopneas during a Polysomnogram? Did they show up after you started using a machine? Short episodes of CSR and brief periods of periodic breathing are not that uncommon. This is especially the case after one starts using a CPAP machine. The goal for everyone is an AHI less than or equal to 5. Some of us with Central Apnea and periodic breathing would be happy to see an AHI less than 10. What is your situation?

Thank you richb! I'm new to this condition, trying to read and learn as much as I can. In my Polysomnogram, the overall AHI was 12/hr, REM AHI was 16/hr, supine AHI was 12/hr, and lateral AHI was n.a/hr. The central apnea count was 28. Baseline SaO2 was 97% with minimum SaO2 of 83%. The mean SaO2 was 94. The percentage of TST with a SaO2 <90% was 0.2%. The desaturation index was 16/hr. The arousal index was
23/hr. The overall PLM index was 1/hr with an associated PLM arousal of 0.2/hr. It was concluded that I have mild central obstructive sleep apnea.

With CPAP, I'm between 4-6 AHI. With the SleepyHead software I see sporadic CSR episodes of 1min8sec to as much as 2min23sec in different occasions. Not sure what to make out of that.

Cheyne Stokes is a specific type of periodic breathing. If you are searching for more information, do a search on periodic breathing and sleep apnea rather than CSR. I think you're more likely to find something more descriptive of common periodic breathing that can occur from complex apnea, central apnea, and common hypopnea.

Thank you Sleeprider, CSR definition and information really sounds alarming.

Your numbers are encouraging as it looks like you have obstructive events under control. Fine tuning your settings might get rid of the remaining Centrals. You should take note of your machine settings and share them for more comments by members.
