[split] High AHI Levels
#1
My average AHI is over 15. I'm not getting good support from my Dr. or equipment provider. We have moved from Cpap to Bipap and changed masks but my AHI still stays high on average. I have Afib and am hopeful that if we can lower my AHI the Afib will go decrease. I just installed Sleepyhead and this is my chart - any advice or feedback is appreciated!

Hi Hadleyro
Your AHI is mostly hypopneas, if using APAP, I would say bump the lower pressure a bit and should be enough to deal with that. But, since you're using Auto BiPap and have Afib, you'll ned to listen to someone who are familiar with your machine and the heart condition

Your A-fib and periodic breathing are complications that require careful consideration by a professional knowlegable in treating complex apnea. This is not obstructive sleep apnea, and neither APAP or BiPAP are normally effective in treating complex apnea and periodic breathing. You might need to consider an adaptive servo ventilator (ASV), however, that decision really needs a doctor familiar with the risks of your cardio condition and how that is affecting your sleep respiration. A high AHI as indicated by a machine, rather than polysomnograpy is an incomplete picture in your case. I think at a minimum you need to evaluate the degree to which this may be causing desaturations of oxygen, and the risks that could involve.

You appear to have complex apnea, and I'm surprised with your cardiac risk factors you have not been referred for further evaluation at a sleep clinic. This doesn't sound like a DIY project.
