CPAP

I am using fisher and paykel Auto cpap for past 3 months. But I am still feeling sllepy during daytime. I have set range as 5-18. Any suggestions on using the equpment better?

Hello and welcome. Did you have a titration study, and if so, what pressure was found to be effective? If the lower number in the range is way below the pressure required to prevent or resolve your events, it can take the machine quite some time to rise to an effective pressure. Narrowing that gap at the lower end may help. Another common culprit is mouth breathing (if not using a full face mask).
