How is it decided what machine I need?
At present I use a S9 Apap with the EPR set at 3 but I feel that a Bipap would be better for me.
An APAP with EPR is almost Bipap.
The Sleep Centre would know from their readings if you would be better with another type of machine, if you had a home study you need to take it up with your GP and raise it with your Sleep Centre.
I checked with my hospital but they dont supply Bipap,s to outpatients so looks like Im stuck with the S9
