Can a CPAP machine treat central apneas?
I was diagnosed with moderate to severe apnea 8 years ago. Twice I tried to adjust to the CPAP machine, twice I gave up after a few weeks. Then last year I decided to try it again – this time the machine was much quieter and I had a more comfortable mask, and after a few weeks of struggling I was waking up in the morning more rested and alert than I had for many years. Eureka!
But after a few months of this, my AHI shot up from 4 to anything between 6 and 12, and my sleep quality really deteriorated. This has been going on for about 3 months. (My GP thinks it may be because the Corona business disrupted my life, and that as things go back to normal so may my sleep.)
Turns out the CPAP is doing wonders with the obstructive apneas – they are close to zero – but I now have central apneas.
Today I went back to the sleep doctor to ask about other treatments. Without explaining why, he said that he treats central apneas that come after CPAP treatment the same way as obstructive apneas, took me in to the technician and told her to work with me, to raise the pressure. And to come back to him if it doesn't help.
Has anyone had experience with, or know anything about, cases where the CPAP machine resolved central apneas?
