Been using my Resmed Airsense 10 autoset since February 10. AHI during sleep study was 20.1. AHI since using Airsense 10 has been in the 4 to 9 range. Hypos have been 1 to 2, OSAs have been 1 to 2. CAs have been the vast majority of events, roughly 60% to 80% plus of nightly events.
Last night the same pattern emerged. 1 hypo, 1 OSA, 4 plus CAs per hour. I tracked my awakenings and they occurred coincident with the CA events.
I am generally pleased with the therapy. Pressure settings seem to be fine (auto, 8 cmH2O to 14 cmH2O, with peak pressure usually approximately 11.6 cmH2O). My next appointment with my cardiologist is on 4/22. I will continue to track my therapy using sleepyhead and if there is no improvement in the CSAs, I will be asking for a new machine to eliminate the CSAs. Thoughts?
The fact that most of your apneas are central may be indicative of another underlying health issue. The machine you're using will only help with hypopneas and obstructive apneas, so this also might not be the best machine for you (there are machines or other treatments that address central apnea). That said, I suspect this is worth follow-up discussions with your cardiologist and sleep doctor.
Thanks Possum. Luckily, I have really no other health issues than the OSA. I am under "preventive" cardiology care due to a family history of premature CAD. My cardiologist is my sleep Doctor. I suspect that I may need and ASV type machine due to the CAs. I will monitor this for the next few months to see if improvement occurs as I understand occasionally happens. If not, I have the data to push for a machine change.
