How to get correct pressure

Posted by sleepysandy on November 23, 2001 at 06:16:31:

It would seem that getting the correct pressure after a sleep study would be an easy matter. However, my Dr. tried several settings with the CPAP from 5 to 12 and lots in between and then decided to put me on an Autoset T to help diagnose the appropriate range. The auto setting was 4-8. When she looked at the data after a week, the mask had leaked so much )full face mirage) that she couldn't get a good handle on the inforamtion. She then had me come back after 3 weeks, mask adjustments, etc. MY new results showed that I have few leaks, no apneas (or less than .4 somethings which she said was not significant)but my concern was that the pressure stayed at 8 (the max) almost the whole time. So she moved it to 10 (at my request) but that night my mask almost blew off my face and I had lots of leaks all nite. So back to 8 again. I am sleeping pretty well 3-4 hour shifts with minor wake ups to adjust sleeping with some little leakage that doesn't seem to affect machine. My qustion:
1) Should I be concerned that the max 8 on the autopap is what my pressure will be probably be established at when she puts me back on CPAP?
2) Could the machine be missing things or not recording stuff because the max of 8 is as high as it goes and it stays there all night almost?
Thanks for all your help.
