I'm in searching for a BiPAP machine for my father who recently diagnosed with ALS and has trouble breathing deeply. His CO2 level is rising as a consequence and he is feeling weak.
I did some reasearch online, and frankly am quite confused with the different versions of the bipap machines. I find ResMED S9 series which I think it should fit for my father as the machine claims to be very quite. My question is which one should I choose, the S9 VPAP auto or the S9 VPAP s/t.
And what's the general suggestion for the starting EPAP and IPAP?
