A bilevel machine switches between a high pressure (IPAP) for inhale and a lower pressure (EPAP) for exhale.
In S mode, the machine is in "Spontaneous" mode. It detects when you change from inhale to exhale.
In T mode, the machine is in "Timed" mode. It decides when to go from inhale pressure to exhale pressure.
In ST mode, the machine operates in S mode unless you stop breathing and then it switches to a form of T mode. This is a way to treat central apnea.
I believe the VPAP ST machine will do all three modes. It does not do auto adjusting.
The VPAP auto does NOT do T mode or ST mode. If you need T mode or ST mode for central apnea, it won't do it. The VPAP auto is not "superior" to the ST, or vice versa. Either one does things the other one doesn't
If you have central apnea, the VPAP Adapt does ASV mode, which is sort of a super ST mode.
Well, that's very informative!
