I returned to my old S8 Escape set to the same pressure and it nearly blew my eyeballs out.... on the S9 Autoset it is very low (pressure) and I have to suck to get enough air. Not right.
Am going to get a manometer to have some solid empirical data but the deficiency is so obvious.
Machine purchased just over two years ago online. Can it be taken to ANY ResMed dealer with receipt for repair?
I'm probably stating the obvious, but check the pressure with the air filter removed and with no humidifier. Unplug the machine for several minutes.
You can make a really quick and dirty manometer by sticking the end of hose into a bucket of water and slowly raising the end until bubbles dome out. How far below the water in centimeters is the pressure in cmH2O. Be careful, it will tend to blow water everywhere, especially if you use something like a glass of water.
