Which S9? Remember the model names.Zzzer wrote: Now ... ResMed S9 or Respironics 460 ??? I
Elite is like the PR S1 460.
Any S9 with Escape in the name is either a total brick or has such limited data available as it is pretty much a brick.
There are 4 S9 ResMed machine models in the cpap/apap line.
S9 Escape...hours of use only...a brick
S9 Escape Auto...hours of use and gross AHI only...not much better than a brick
S9 Elite..straight CPAP and full efficacy data
S9 AutoSet ...cpap and apap modes available so like 2 machines in one.
Before the 60 series with their heated hose option I would tell you the S9 machine with their heated hose was probably the better choice but now it's really a toss up. Minor pros and cons with either.
At least with the 460 machine there is limited APAP mode availability...I think it is limited to 30 days and can be reset to give an additional 30 days 5 times...so 150 days available in apap trial mode.
So between the S9 Elite and the PR S1 460 machine....I would go with the 460.
