Cheynes stoke respiration, false flag or accurate? - BDGold99 - 03-27-2024

Age - 24 male
5ft10 160 pounds
AHI 16 on sleep study
Mask - Airtouch full face
Machine - Resmed airsense 10
Other - Wearing mouth tape and knightsbridge chinstrap.

Im struggling to keep a cpap mask on all night so my data is very fragmented and i never get more than a couple of hours. Some sections of the data i am awake or half asleep and i cant remember exactly when at which points, as i often pull the mask off while asleep because im extremely tired. 
Last night cheynes breathing was flagged so now im worried. Does anyone know if i should be concerned about this? I have a strong family histroy of cardiac disease.

Here is a picture of CSR.  Like several footballs or tennis balls on a string.

If you could show a 3 minute close up zoom of the area where the purple cluster of bars are, that would be a better OSCAR snapshot to evaluate.  I am not qualified to diagnose CSR, but the best move would probably be to show these charts to your PCP (or Cardiologist).  The vast majority of CSR flagged are false; but with a family history of cardiac disease, it seems like it could be a possibility.

Hi jay, thanks for taking the time to reply. I think it may be a false flag as over the past two days ive been able to wear the mask for a good amount of time. I've also managed to get the AHI down to 0.5 for both nights and the first time ever. I've never used cpap for this long in a night and had such a low AHI. However, the flow rate looks very up and down for a large majority of the night instead of the consistently level flow rate you would hope to see. I also woke up feeling quite oxegen desaturated, but i dont have a headache so its an improvement i think. I think i remember frequent awakenings, but not due to leaks. Maybe this has resulted in less REM sleep? I wonder if you would take a look at this if i upload some pictures, to see if its normal or if there's anything I can do to improve that you may suggest. I would really appreciate it and thanks again regardless.

Clear airway apnea clusters and apneic threshold periodic breathing that you are describing are common issues, particularly with new users https://www.apneaboard.com/wiki/index.php?title=Optimizing_therapy#Clear_Airway_Clusters We see an oscillating airflow in many people and it is a sort of feedback-loop or loop gain of respiratory drive which is driven by carbon dioxide. When carbon dioxide builds up in the blood stream it stimulates the respiratory control centers and causes that person to breath faster or deeper, then as carbon dioxide diminishes, respiratory drive is diminished resulting in reduced respiratory volume or pace, and can even result in a central apnea. The first link is to the Optimizing Therapy wiiki on these central events, and this one explains Loop Gain. https://www.apneaboard.com/wiki/index.php?title=Loop_Gain_in_Ventilation

Resmed labels any kind of periodic breathing as CSR. Its more than likely not true CSR. There also could be some sleep-wake junk as your sort of falling asleep. Many people experience pauses in breathing as they begin to fall asleep.
