My nurse/practitioner could not handle the fact I was waking most mornings about 0300-0400 and clearly had no intention of doing anything about it.
I paid to see the senior man, his best effort was to suggest I went to bed later, and that I see another nurse regarding a change of mask, which I had not raised as an issue, leak rates being reasonable.
Sounds like your quacks are as much use as ours.
The only reason I am taking further action is in the hope I might get my driving license returned, were it not for that I would likely say stuff it and let nature take its course.
When you do your Doctor shopping, be sure to ask if they are familiar with Central Apnea and Periodic Breathing. If you have a teaching hospital in your area you might want to start there. The standard treatment for Obstructive Apnea (CPAP) does not work for most cases of Central Apnea. An ASV machine is the usual treatment for Central Apnea. You will want to confirm that your new Doc will prescribe an ASV machine if your diagnosis is Central Apnea. Note that I mentioned Periodic Breathing. Periodic Breathing will look like Hypopneas during a Sleep Study. The Periodic Breathing can cause desaturations of O2 that keep you fromn sleeping deeply. A standard CPAP machine will convert Periodic Breathing Hypopneas to Centrals therefore the increase in Centrals. You did not mention that you had Obstructive Apnea events during your Sleep Study. Your Doc may have been counting Periodic Breathing events as if they were Obstructive in nature. Look at your sleep Study to see what was reported. An ASV machine can treat both Obstructive and Central Apneas. The initial settings might be different depending on whether Obstructive events are present. Sleeping on your side can also eliminate many Obstructive events but will not change the Centrals. Stay in touch and keep reading threads on this site related to Central Apnea.
