Sleep Data Help Please

[woodworkerjunkie]

I was on straight CPAP at 9 for the sleep study and zero events. Could this be from the hose moving around while sleeping? I have the machine at the foot of the bed and the hose gets moved around alot while I while sleeping.

I agree with everything Burkebang has said, I would just add that I believe that you should increase your lower number up to 8.0. You said your cpap pressure was 9.0 with 0 events, so you shouldn't go to far below that number, or your machine will have to play catch up all night trying to get high enough to fight the events. In your graphs the pressure would drop back down and as soon as it reached the bottom, you would have another event and it would have to start the climb back up to fight the event. You might try a setting of 8.0 to 15.0 then get a few days readings to see where you stand.

Here is the sleep data after raising the top end to 12. Still having a bunch of events is there anyway that I will be able to stop the events? Any suggestions would be greatly appreciated.

Just saw your post woodworking will change the settings after one more night with these settings. Will post again tomorrow thanks again.

You have gone from an AHI of 3,20 to 1,94 and 25 events to 14. You are doing better than most people who do not have sleep apnea
How do you feel? Any difference?

I would say that your medium pressure is around 9, what does Sleepy head say below the event breakdown wheel? Your machine is not maxing out much nor bottoming out. I would say that you are well regulated and that you should give the new settings a few days to settle in.

Raising the top end to 15 as Woodworker says makes sense, to have a bit of a safetymargin. If you had done that, your pressure graph would probably have been just the same as today, you got the pressure the machine wanted to give you. When it comes to raising the minimum pressure, I don't think it will make much difference for you. When your events happen, your machine is usually nowhere near the minimum pressure, so raising it would not give your machine much of a headstart. From 03.00 to 05.00 you did'nt score a single event and probably slept very well with nice and low pressure. Raising the min could lower the quality of that sleep a little bit by increasing your overall exhaleing effort. I think you should consider the min pressure as a comfort thing. If you are more comfortable breathing at 5 than with higher pressures, leave it as it is. If you feel like you don't get enough air at 5, raise it a litte. In that case my suggestion would be that you try 7 first. Looking at the bottom part of your mask pressure graph makes me think that 7 would be a good min pressure for you, that will allow the machine to do it's thing, mostly.

In the flow rate graph, use your mouse to zoom close in on each obstructive event. Click shortly before and drag your mouse to slightly after each event. Now you can see excactly how long each event lasted. This will give you an idea of how serious they are and you can decide from that if you are willing to loose comfort to try to get rid of them. You can also post what you see here. Remember that the important thing is to sleep well, that should not be sacrificed in the hunt for perfect data.

Thanks again for all the help looks like I will stick with these settings and let them do their magic.
