Jeff:

You are most likely correct in saying that there were two devices
in one can (or two chips in the same housing), one for 660 and
one for 925 nm.

I worked for a company that manufacured Pulse Ox's (hence the
anonymous post). ALL of our stuff had two LED's in it, and I
saw no R&D by "us" or the competition towards a 1 LED system,
ALTHOUGH I think there was a way of doing it.

I wouldn't trust any 1 LED system. 

BTW, if this hasn't been discussed before, pulse oximetry
gives the percentage of oxygenated hemoglobin in the arterial
blood vessels. A reading of over 94% is nice, less than that
MIGHT be a problem - it depends on the situation.

It gives the heath care giver a quick read on the status of 
the circulatory system. It's a much earlier sign of a problem
than blue skin is!

If you are going to have a procedure done on yourself, make
sure there is a pulse ox put on you!
