Now, if I may offer some advice of my own: To those folks who have not yet chosen a machine but have already "failed" their sleep study; choose a machine that provides at the very least, leak rate data!!!!
LEAK RATE!!! This is a VITAL piece of information to have that my machine does NOT provide. If your leak rate surpasses what is deemed as an acceptable number, you will obviously reduce the effectiveness of your cpap therapy. If the number is high enough, you may get NO benefit at all!
My S9 Escape (ResMed) only provides the bare minimum of a daily usage and an average daily usage (mostly for justification for the insurance companies). I wish it had at the very least, this leak rate feature and also, a "mask fit" feature.
I will "lobby" my DME on Monday and if unsuccessful, talk my with Doc about the need to see this hard data vs just feeling ok, in evaluating my progress.
Hope this helps those that have not yet made a choice in a machine.
Have a great, safe weekend!
