How your CPAP reports its own use — from your nightstand to the records.

The three numbers you'll see, side by side — and who reads them.

Your CPAP machine does something you may not realize: while you sleep, a little modem inside it writes down how long you wore the mask and sends those numbers off on its own. Medicare uses them to decide whether it keeps paying for the machine. This guide isn't about how to use a CPAP — it's about the data: what gets reported, the 'compliance' rule in plain words, where to see your own numbers, and what to do if the early weeks are a struggle.
