Immediately before recognizing the sleep apnea I was in contact with my Cardiologist to discuss the onset of edema and un-expected weight changes.

Ejection fraction tested as 55 and subsequent weight stabilization appeared to clear my concerns; however, the breathing abnormalities and return of other symptoms have brought back cardiac concerns.

I have all of the symptoms of right-side hf. I do recognize that there may be other reasons for those symptoms.

The patterns of my breathing appear to me to be consistent with those concerns. Am I reading the breathing patterns incorrectly??

almost every source that explains central sleep apnea or adaptive-servo ventilation (ASV) includes a discussion of a type of periodic breathing called cheyne-stokes breathing, which is associated with congestive heart failure. you have a clear pattern of periodic breathing often followed by flagged clear airway events. many of us have indications of periodic breathing with no known heart failure that probably isn't cheyne-stokes breathing. no idea if yours is really cheyne-stokes and I know nothing about heart conditions. but given your description I'd say (guess) your observation may be correct. I'd want to show the SH graphs to my doctors just to see if it's useful info to them and also to receive a more definitive answer to your question.

in previous post I said you have a clear pattern of periodic breathing often followed by flagged clear airway events. looking further, I see you do have that pattern but also a less well-defined periodic breathing-looking flow punctuated by hypopnea and obstructives. that variation might muddy the water a little with respect to the prevalence or potential implications of the pattern I first referenced. higher pressure with your current machine might resolve some of the h and oa and help clarify what's going on with the pb and ca. they might increase, in which case you probably have mixed apnea which can be treated with asv (depending on your heart condition), or they might resolve in time if you have complex apnea (cpap emergent ca). I'm no expert so maybe some more experienced members will comment.
