How can you measure respiratory effort with a sensor stuck on your forehead? You think you can reliably differentiate central vs obstructive apneas from that technology (in reply to your question (although admittedly this is another question) from the other thread)?
Even if it could, Watermark ARES raw data are not reviewable (so bona-fide sleep laboratories cannot use this technology). It simply goes up to the The Cloud and they spit out a number ("Trust Me - The Check's in The Mail!").
This is all academic anyway, since ARES had to pull the effort channel out in March 2011:

I mean I know how it works, and in fact, that it can work (the idea is that if you're sucking in from an OA, your CVP changes, but in a CA you don't and it don't).Sludge wrote:You think you can reliably differentiate central vs obstructive apneas from that technology...?
But apparently, the FDA doesn't agree.
