Need some advice on setting the range
Re: Need some advice on setting the range
[quote="eljay"]Hello everyone. I've been reading this forum for about 6 weeks and have learned a lot from everyone. I've learned so much, in fact, that now I have a question I hope you can help me with.
First, some background. My primary care dr had me do a sleep study because I complained of excessive daytime sleepiness. During my sleep study I had an AHI of less than 1. Sleep dr said "patient did not meet criteria for the diagnosis of OSA....However it should be noted that at least 20% of patients with negative sleep studies for OSA if retested will have significantly different results. Since this patient had a very poor sleep efficiency (less than 50%) and delayed sleep onset that is certainly possible....Patient should discuss these results with patient's physician...I have no specific recommendations regarding this patient."
So I discuss with my Dr. She suggests trying CPAP for a couple of months to see if I feel better, I say ok. DME sets me up with an APAP with at range of 4 - 10.
So here we are 6 weeks later. I've gotten used to the machine, can get to sleep, wear the mask all night, don't wake up as much, don't have to go to the bathroom as much, but also don't feel any better during the daytime.
A couple of weeks ago I took my card to the DME and had them download the info. My 90% pressure for the month was 6.3, avg AHI 2.8. The Summary of Daily Events, for the previous week looks like this:
4 cmH20 for 61% of time, AHI of 1.8
5 cmH20 for 24% of time, AHI of 2.0
6 cmH20 for 7 % of time, AHI of 4.2
7 cmH20 for 5% of time, AHI of 4.5
8 cmH20 for 2% of time, AHI of 0
9 cmH20 for 1% of time, AHI of 0
10 cmH20 for 0.5% of time, AHI of 0
I'm confused about why the AHI goes up as the pressure goes up, and then drops to 0 at 8 cmH20. If the pressure needs to be that high, it seems like it would be there more than 3.5% of the time. But what do I know?? So that's why I've finally registered and am making this first post, cause I'm sure you all can help me out
Sorry to be so long winded, I'll try and be more succint in the future...
