The thing about sleep apnea is that it goes hand in hand with a multitude of health problems including A-Fib and heart failure, Heart attack, COPD, Arrhythmias in general along with Generalized mortality.
There are other treatment options available besides C-PAP machines. I have to say that DH does fantastic with his. His number of events when they did his first sleep study was very high. His second study where they tried him on a C-PAP eliminated them by like 95%. His cardiologist told him that without control of the apnea, control of his A-Fib would be a lot harder. Good motivation.
Well I knew my last test was good because they always start off with no mask and usually bring it in when I have too many episodes. They never brought it in all night.
Personally, I wouldn't count on mouth tape. What happens if your nose plugs up due to sinus problems, colds or allergies? I'd suffocate as my sinuses are always partially blocked. The CPAP head unit that he uses forces him to breathe through his nose. I tease him that when he opens his mouth it sounds like I'm sleeping in a wind tunnel but other than that all we ever hear is a soft hum from the motor in the machine itself.
Anyway, the stress test is canceled yet again.Half of it anyway. Still trying for the other half. Waiting on a call back.
