From what I’ve read, central sleep apnea requires a more sophisticated machine then a basic CPAP. The doctors will argue with you up and down which type of sleep apnea you have. I’ve been there.
It’s called a bi-pap and I was prescribed one in April. Started my weight loss in june and am down 65 pounds since. Having a new study done to reduce the pressure of my device - loss of that much fat has allowed the machine to push air into my gut and I’m waking up in a lot of pain.
I’ve been using software called OSCAR (old “SleepyHead”) to analyze the data written to an SS card on my CPAP machine. It says about 75% of my events are Central. My sleep doc agreed with me. I have a follow-up consultation in mid March.
