So I am new to CPAP, my doctor gave me this airbase CPAP machine which he say's is automatic, The problem with the machine is, it has min and max pressure settings upto 4 - 20, and whatever the max pressure is set it reaches that pressure within 10 -15 minutes, yesterday I set the max pressure on 20 and kept the mask on and I was watching TV while I was just sitting on my sofa and the pressure reached 20 within 15 min, does the auto CPAP machine works like this.
