First off, I have very limited experience with BiLevel machines. They do seem to have a purpose but it seems to have more to do with respiratory issues rather than obstructive or central apnea. On the auto pressure thing, my thinking has evolved. On the surface it seems that an auto machine is a great idea as it just uses enough pressure to do the job and no more. And then when you do need more they adjust upward to give you more. The problem with this is that they constantly reacting. You need to have OA events to prompt the machine to give you more pressure.

I have come to the conclusion for basic apnea a fixed pressure machine is better. It does not need event prompts to give you the right pressure. If you have done your homework you start each night with the right pressure. For someone that gets into treating apnea with a home test and no titration test for pressure an auto machine is a good idea if you monitor the results with OSCAR. It will tell you what the right fixed pressure is, and then you can switch the machine to fixed CPAP mode.

An ASV machine is very different. It tracks your breathing breath by breath and corrects each one. It is much more sophisticated and in some cases can be the only good solution for central apnea that can't be addressed by minimizing pressure.

Just my thoughts.

agreed, but I thought maybe I was missing something.
