The finger sensor in the picture on the blood gas monitor page appears to be upside-down; the wire should be trailing off the top of the finger, shouldn't it? (I'm no expert.) Peter 05:10, 20 September 2005 (UTC)

Always used this one like this... perhaps different models have different usage, I don't know :p Rama 07:18, 20 September 2005 (UTC)

[edit] The move

I have never heard about noninvasive devices measuring pH, pCO2 or other blood gas values. The term "blood gas monitor" is incorrect and confusing, so I moved this page to "pulse oximeter", which is a much more current term. I will adjust redirects.

The page is terribly dumbed down. It should discuss the principles of the different light absorption patterns of oxygenated and desaturated Hb. I'm running late, so I will not be doing it just now. JFW | T@lk 16:53, 20 September 2005 (UTC)

OK, there is end-tidal CO2 measurement, based on completely different principles. JFW | T@lk 16:55, 20 September 2005 (UTC)


I added reference to Photoplethysmograph. If you want I can edit this entry. --Spl4 04:53, 9 November 2006 (UTC)
