Actually, occasional central apneas are very common; very, very common. (Many people have them when falling asleep and sometimes when transitioning between sleep states.) And home machines that are full-data see all apneas, central or obstructive--they just aren't usually very good at knowing whether an apnea was obstructive or central. Full-data machines ARE a flow gauge. A very, very, very reliable one, as long as leak is under control. It is true that home machines don't score like a PSG, but the data ones don't miss apneas.
Yes, you are right, Duane. Wrong information can be dangerous.
Rock, ignoring a central as nonsignificant, and thus not scoring it, does not mean it didn't happen. My point is that the home machines score them all, according to their criteria. To a home machine, an apnea is an apnea and a hypopnea is a hypopnea, central or obstructive. Some home machines try to guess if an event was central or not, but it scores the change in breathing either way.

Ha! :-)
The machine manufacturers hate me, Duane. I am a thorn in their side, a bane to their existance. My position is that the DMEs, their real customers in the USA, dictate too much to the manufacturers. It is my position that the reporting technology in the home machines is behind the times and that the machines are overpriced due to ugly minimum-advertised-price gouging. I will shake a manufacturers hand, yes, but I will not pat them on the back, any of them. Why is my overpriced blower dumber than the cell phone on my belt? Why doesn't it have a color screen that shows me my daily leak and AHI in chart form? Because big business doesn't think it important for me to have that--that's why.
Still, the machines are the gold-standard treatment, and customers deserve machines that give them efficacy data. If I had my way, it would be illegal to sell a non-efficacy-data machine in the U.S. That makes me an enemy of manufacturers and DMEs. Doctors, on the other hand, just smile and wink. ;-)
The info from the machines is not as good as a PSG. But it is the best data available to a patient when it comes to getting good therapy over time every night, so I am an advocate for it as a patient.
I humbly submit that you, as a professional who cares about patients, should be an advocate for that too. Let us share the agenda of good treatment and good information for patients, even patients as contrary as I can be. :-)
I do, however, take my hat off to techs and therapists who want patients to be equal partners, at least, in their own PAP therapy.
