- 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!
