After being diagnosed in 2011... and failing to tolerate a CPAP back then, I'm giving it another shot (just had a 3rd sleep study done and my neurologist is pretty adamant about taking care of my sleep issues before we attack my other symptoms).
So... I dug out my machine... it's a ResMed S9 AutoSet (with heated hose and H5i humidifier) and the mask they fitted me with at the time was a Quattro FX. At the sleep study I just did last month, they fitted me with a ResMed AirFit F10. So... new mask... and the old mask had very little use so it should still be good.
I'm having a few problems tolerating it. I've been attempting to use it for 41 days. My 30 day average is 3.5 hours, and my average for the last week is 4 hours, 41 minutes. I did find my way into the clinicians settings. It had previously been set to a fixed pressure of 6.2. I changed the mode to auto (which was probably good as I often see the pressure is going above that) and I enabled the EPR and set it to 1. This has made it a little more tolerable.
Last night was actually my record, 7 hours, 10 minutes (pretty remarkable as I have a few years of sleep tracking data with the Sleep Cycle app and my average night is about 5.5 hours of sleep). It's not a straight through, peaceful sleep though. I wake up multiple times throughout the night to futz with the mask. It also takes me longer to get back to sleep.
The main problem I'm having is that after several hours of sleep, I wake up, and when I try to go back to sleep there's a leak at the bridge of the nose. Unfortunately there's no more room on the head gear to cinch it down anymore. I figured loosening the lower part of the head gear might help (as it wouldn't be pulling up on the nose) but it doesn't. My theory is that throughout the course of the night the head gear is stretching a bit, making for a looser fit. Sometimes switching to whatever mask I'm not wearing at the time helps.
My doc wrote a prescription for a new machine and a new mask fitting so I'm waiting for that appointment (it's tied up in insurance wars right now). Is there anything anyone can suggest trying once I do get to that appointment? (just in case, a nasal mask is unfortunately not an option as I have asthma/allergies and my nose isn't always clear). At the most recent sleep study fitting in January the tech tried different headgear sizes on me... I believe the medium was definitely too small.
