When you turn on the machine and it finishes its self-test, you should be at the main screen where you can adjust the ramp time. Ramp is a setting that gradually increases the pressure up to the set pressure. However, if you are in auto mode, you would see "Settling Time". That's the amount of time...

Thank everyone for the advise. Also what is the RAMP. How do i turn the pressure up? It is set at 10-15

I just started on the cpap for a week. The longest i have keep it on is maybe 2 hours at night. I just can't seem to relax and go to sleep. I also feel like i being suffocated when i breathe out. Is this normal ?
