Sam, you summed up the problem beautifully. The field of "sleep", especially as it pertains to etiology of OSA, cortical arousals, fragmented sleep architecture, etc.... it's still such a young science.
You're exactly right, Sam.
Even if the workings of the various black box APAPs were described
completely by the manufacturers, that
doesn't mean doctors would automatically (no pun intended!) be able to select the "right machine" for each patient.
Actually,
even if doctors
were able to prescribe the perfect machines for patients A, B, and C, those people are
not going to get effective treatment as long as the
masks they are given are uncomfortable and leaky.
The #1 ongoing problem (in my opinion) is in finding a
mask that doesn't wreck sleep. Match people to the perfect machine...but then just hand them "a mask." Most
will drop out. Eventually, if not right away.
Until
mask COMFORT issues are addressed
much better by the manufacturers and the DMEs than they have been to date, it's not going to matter how well the machine itself suits them, other than can they exhale ok with it.
For the vast majority of OSA patients, the
mask is the real key to effective treatment -- much more so than which machine is chosen. Just my opinion.
Of course, even if machine and mask are both "perfect" for a person, when you throw other factors into the mix...other underlying health conditions that xpap can't really do anything about...you can still have people feeling worn out, awful; no matter how effectively their OSA is being treated. You can still have people dropping out of effective xpap treatment because they don't really feel better...for other reasons.
