I have had sleep apnea for over 20 years. Recently I started to be more proactive in trying to improve my quality of sleep. I figured out by downloading the clinicians manual how to take control of my S9. I have struggled with being compliant with this machine that I have had for a few years and am now starting to understand why. A typical nights sleep used to be an AHI of over 20. my machine was set up so that I could not see my nightly AHI.. it was only after I set it and could see how badly I was sleeping that I confirmed what I was feeling.. horrible sleep.
I also discovered that the EPR was only set to be active on ramp which I immediately changed. Whats the point of having a feature that you don't use! My r/x is for 15 and my machine is an autocpap and was set from 9-17 with a 45 minute ramp with EPR. I recently went in to the provider of the machine and the technician suggested based on the data that I remove the ramp completely if I can tolerate it as I get a significant amount of events as the ramp is coming to an end. Typically I have a large number of events each time I start or restart my CPAP if I have gone to the toilet. Now here is my first question, last night I had several central apnea events at the start of the night when I was still awake.. and I know this because I looked at my watch at the exact time these events were recorded.. and yes I have the clock set correctly, another thing I fixed!
I have been slowly adjusting my low end setting to see if I can reduce my events. Tonight I have set the low end for 12.4 and 17 is still the high end.I rarely touch the high end when on therapy. my EPR is set to 2 and I have removed the ramp.
Any thoughts would be great.. I have attached a screen capture to show you the graph for last night.
Thanks in advance for any input
