[edit] The

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)
I don't think it makes much of a difference. In my experience, they will work in either orientation. I believe common orientation is with LEDs on top, which is why the wire is on top.Dmcmorris 09:36, 24 December 2006 (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)

Yes, please do improve this article. --68.0.124.33 (talk) 23:34, 5 February 2008 (UTC)

[edit] who invented

Does anyone know who invented the pulse oximeter?

From what I could gather via Google, a certain Dr. Takuo Aoyagi is credited as the "inventor" of the pulse oximeter. Couldn't verify this other than the fact that it was cited in a lot of search links Animeronin 18:37, 7 October 2007 (UTC)

[edit] How accurate are the inexpensive fingertip monitors?

I've wondered about the accuracy of the fingertip oxygen monitors. Any information? 67.42.157.137 19:57, 30 March 2007 (UTC)

can sumone tell me hw essential is it 4 the red LED to be on the finger nail side.... is thr an arguable reason 4 this???? the question tortures me...:p

[edit] Unverified Claim

Can someone verify this?

Pulse oximetry is the most important safety development in anesthesia.

I have no diea where to put this from. Any ideas? --Animeronin 18:44, 7 October 2007 (UTC)

[edit] merge

I suggest merging "pulse oximetry" into "pulse oximeter", discussing both topics in one article. There is enough overlap in talking about "the measuring instrument" and "the process of measuring" that I don't see the need for separate articles. Do we have separate articles for thermometry and thermometer? --68.0.124.33 (talk) 23:34, 5 February 2008 (UTC)

[edit] Merge the OTHER way

I suggest pulse oximeter be merged into pulse oximetry... this makes more sense, since the main topic should be the main article, and there should / could be a sub section for a particular tool used for pulse oximetry. purpleidea (talk) 21:38, 4 March 2008 (UTC)
