I use an Aircurve 10 vauto and I use the amara view minimal face mask. From the first day I started on my bi-pap I have had Central apneas recorded by my bi-pap. However, I had no central apneas in my sleep study. I do not believe that the CA's recorded nightly are true centrals. To prove my point I purchased a camera and recorded my sleep for a few nights. The first screenshot shows my flow rate when I am sleeping normally. The second screenshot shows my irregular breathing followed by a CA being recorded. In almost all instances such as this when a CA is recorded my video recording shows me as rolling over.
My question is am I right in assuming that these are not central apneas but instead are just arousals from rolling over ?
As for the PLM's, I get anywhere from 20 to 30 a night as revealed my my camera. Since my sleep study stated that they appeared to be related to airflow restriction I'm wondering if I should be adjusting my EPAP or IPAP or both.
Any suggestions ?
Almost all of the UF #1 & UF #2 are recorded when I have a leg movement as revealed by my camera .
My present settings are : IPAP 13, EPAP 7, and PS 3.0. I had adjusted the original settings over time due to a problem I was having with the machine not being in sync with my breathing, but that problem has been resolved over time .
I might add that I am 76 years old and in good health,walk 3 miles a day, and take medications for allergies for my eyes and nose as well as taking 5mg of zolpidem each night to get me to sleep as I have had insomnia most of my life.
Due to the number of times I roll over and also due to the number of PLM's , I end up with a very fragmented sleep. My AHI has been good at an average of 1.8 for the last 6 months with 1.4 of that being CA's(which I doubt are really CA's). Due to the fragmented sleep I am always yawning after about 11:00 a.m.
Any suggestions as to pressure adjustments
