They said the pressure should be 13 with flex. The supplier didn't want to do the flex. I was waking up with a mouth full of air. I then had them ( though my primary doc) set it to auto between 4-13. I am getting better sleep and the machine is saying the max is now under 10. You are correct in that I should have had the full mask in the study. While on 13 my AHI was under 2. Now at 4-13 they are under 7. So my question is how bad is 7 vs 2 AHI but getting more sleep. Couldn't sleep last night so tried an experiment. Put the mask on and watched tv and played poker. After 2 hours took it off went to sleep. Woke up later, put it on then fell back to sleep. Here are the numbers:
Obstr. Apneas. 3 Hypopneas. 12 Time 2.02 hours
Then after sleeping Obstr. Apneas. 5 Hypopneas. 20 Time 4.34 hours
So awake and breathing normal is worse then breathing while sleeping So now I am lost
Does your machine have a ramp and flex feature? Maybe your machine is set to high. I got them to set mine to auto. Before I would wake up and push the button to go back to 4 with a 30 minute ramp time which gave me time to fall back to sleep
I had a sleep study done they didn't have a full face mask available the half mask didn't fit so I use the nasal pillows at the end of the survey they decided that my number should be 13. First week on my CPAP I averaged 13 AHI and slept around 4 to 5 hours.I convinced the supplier to switch to flex. After a month my AHI went down to around 2 my sleeping increased to 5 to 6 hours however I will still waking up with the Air blowing too hard. I then convinced my supplier to switch to auto. My sleeping increased to 6 1/2 to 8 hours however my AHI also increased to between 4-6. My pressure was at 13 fixed. With auto it veries between 7-9. My question is which is more important to have more sleep with a slightly higher AHI or less sleep with less AHI's .
