Changes

I see 2 big steps.<br /> First, you need to change doctors to a doctor that treats Central Apnea. By that, I mean one that actually prescribes ASV machines with some regularity. Realize that all doctors 'treat' Central Apnea. Also note that most doctors only treat OSA, even though they 'treat' Central Apnea. Any doctor that routinely prescribes ASV machines is likely much more aware of what is required than other doctors, these doctors are the ones you want.<br /> 

third whenever you go in for a sleep study, if not a sole study of ASV request a split study that includes ASV, If you have Central Apnea, an ASV titration has a very high probability of demonstrating success. It is much easier to get an ASV if you have a titration demonstrating that it works for you.<br /> 

1. # This method is not supported by everyone. You always treat yourself at your own risk.2. # Verify that you have a Central Apnea other than one based on CO2 in the blood such as [[Treatment-Emergent Central Apnea]] (Other much cheaper techniques can treat this) There is no sense in getting an ASV if you don't need one.3. # Procure a used ASV on the secondary market. (Craigs List, e-bay, you got the idea,4. # Join a self-help forum, set up your own thread so you can maintain a history. http://www.apneaboard.com/forums is a good one with many ASV users contributing This is a very important step because this is your support.
