Hi! I've only used a CPAP for 3 nights and I know I have a long way to go in terms of knowledge, experience, and getting used to the therapy. The first two nights I tried using a Dreamwear FF mask but that was miserable. I borrowed a F&P Simplus for last night and had a much better night. I've looked at the data from the last couple of nights and I notice something happening that I don't understand. The machine seems to ramp up pressure on its own. Some times it seems to only be correlated to increased in "flow limit." Can someone please explain what "flow limit" means?

Thanks in advance!

The machine will increase pressure in response to all four of the types of sleep disordered breathing that are explained in this video.

Thank you for posting that. I didn't find much description of flow limit and I erroneously assumed it was something causing the flow from the machine to change. Now I understand it's an indication that my airway is starting to collapse and now the charts make more sense.
