Shortness of breath - Related to Sleep Apnea or not

Have been on CPAP for over six years now and results were very good. During the first Lab tests, I was diagnosed as 65 AHI and CPAP was set to 9. .... About 2 years ago, I started having shortness of breath issues just sitting in the recliner or at the dining room table. Most of the time my AHI is below 5 but now its fluctuating and last night it was 29.5 AHI. Leaks were good and I slept for 9.25 hours. Earlier in the week I had a cardiac Catheter and apart from AFIB, there were no blockages or other issues with the heart. Issues have even escalated and I've returned to stopping breathing if I doze in the chair and wake up just gasping for air. This is getting painful even. Has anyone else experienced issues after being on CPAP for several years?

Wow. I won't attempt to comment on the medical aspects of your current state of health as they seem to indicate something serious. I would start by going over this with your primary care physician and see which direction you should go in. Good luck. With no leaks and high AHI, suggest that the pap therapy isn't effective as the cause of the high AHI may not be a restricted airway. I highly recommend you talk with your physician.
