I am trying to get my ducks in a row for my appt. with the sleep doc
The fact that your median pressure is 15.9 means that 50% of the time the machine is running your pressure is AT or BELOW 15.9 cm. And 50% of the time the machine is running your pressure is AT or BELOW 15.9 cm.
The fact that your 95% pressure is 19.9 cm means that 95% of the time the machine is running your pressure is AT or BELOW 19.9 cm and 5% of the time your pressure is AT or ABOVE 19.9 cm.
Since 20 cm is the top pressure your machine can deliver, the fact that your 95% is effectively at 20cm is something you may want to bring up with the sleep doc. It's not that it's a definite concern---particularly since your AHI < 5. However, many times sleep docs are willing to switch people at pressures over 15 cm to bi-level machines in part because of comfort issues (the drop to EPAP is more substantial than that provided by either the Resmed EPR system or the PR A-Flex or C-Flex+ systems), but also the bilevel machines can deliver up to 25 cm of pressure if needed.
See the first sentence I bolded. Did you mean at or above 15.9?
See the 2nd sentence I bolded. I saw my sleep doc in early October and expressed concerns that my pressure was at the top of the machine capability. On Oct. 11, I had a 2nd sleep study. Doc's orders were that if I got to pressure 16 to put me on a BIPAP to see what happened but that wasn't done.
At pressure 15, during the sleep study, for 3.5 minutes I had 1 hypopnea, 1 apnea, AHI 34.3, 34.3 Supine REM AHI, 17.1 Central.
At pressure 16, for 29 minutes ONLY, I had 0 AHI. 29 minutes is nothing. We all know that things change during sleep and since I am basically at 20 most of the time, I feel as though 29 minutes with 0 AHI is nothing and wonder why I wasn't either put on BIPAP as ordered OR the Sleep Tech didn't monitor it longer? I didn't have to leave when I did but I was told she had enough info.
So, that money was spent on a sleep study and they didn't see how a BIPAP would do. I did tell my doc that I was concerned that I am at the top of my machine capabilities. I took a report from SH but he said, you should get data from ResScan. When I came for my appointment in Oct. I didn't bring my SD card as I was told they didn't have the program to read it. Today, I found out otherwise. Had I known, he would have been able to see that I was at the top of my machine capability and that it wasn't due to leaks.
So, when I go back in November, we shall see. I will be pushing for BIPAP because I am concerned that if there are occasions I need more than 20, I won't have that option currently.
I know BIPAP is harder to get used to and I don't know if I am smart enough to manipulate it like I can with my current machine, but I just don't feel very secure and this is my life!! I am my own best advocate!
Thanks for taking the time to answer my concerns.
