Hi,
PS is pressure support. That is the minimum difference between inhale and exhale pressure. Your machine appears to be set up in Auto BiPAP mode. The pressure range is set for 10 to 23, with a pressure support of 13, which means that it starts at an exhale of 10, an inhale of 23 (exhale 10 + pressure support 13), and it cannot adjust any higher because it is already max'ed out at 23.
When the machine runs, you should feel the two different pressure levels between inhale and exhale. Another way you can see this is if you take a really deep breath, the machine should time out and make breathing a lot harder after about 5 seconds or so. If it isn't flipping between two different pressures between inhale and exhale, then something isn't working right.
High mask leaks or mouth leaks can trick a BiPAP into thinking that you are inhaling before you start to take a breath, and that confuses both you and the machine. All bets are off when there are high leaks.
Do you happen to know what your prescription is for type of machine and pressure levels? It is always possible that your machine had a glitch and set the pressures funny. I have never seen that personally on my machines, but anything is possible with computers.
