The[edit]

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)

The move[edit]

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.

I don't think that the term "blood gas monitor" should redirect here, at least not with out clear information that pules oximeters do NOT measure blood gases.--Sindritraustason (talk) 07:48, 26 October 2010 (UTC)

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)

who invented[edit]

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)

How accurate are the inexpensive fingertip monitors?[edit]

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

Unverified Claim[edit]

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)

merge[edit]

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)

Merge the OTHER way[edit]

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)

+1 for the merge --MarmotteiNoZ 00:04, 16 June 2011 (UTC)


Please exaplin acronyms such as

COPD?

PVI? —Preceding unsigned comment added by 129.188.33.25 (talk) 15:39, 5 May 2009 (UTC)

Nowhere does this discuss the pulse measuring capabilities of the device, nor the function of the series of diodes that pulse with each beat. I have an arrythmia caused by drug interaction and the measurement of the pulse and the strange readings on the series of diodes make sense to me. I know when I have chest pain the series of diodes does not beat regularly in succession, maybe getting one bar or two. But as the arrythmia has improved after drug withdrawal it seems to light up the diodes in a more regular succession of more lights. What does this measure? What is the significance of these diodes? — Preceding unsigned comment added by 96.245.88.181 (talk) 03:31, 25 July 2011 (UTC)

Images in lead[edit]

Please kindly check out WP:OWN, WP:CON and WP:JDLI. We really don't have to go into this, we've already had the three reverts that pretty much make us both incredibly sad people. I am on sick leave so have a shit load of time to go around editing wikipedia articles.
So, how about I state my case:

  1. There are many different kinds of home-use, clinic and hospital use oximeters, fingertip ones are pretty much limited for home and children's use. Wrist mounted ones are fairly common (At least 7 makers with a few models each, google is your friend here). They have the advantage in that they don't fall off as easily during sleep study or movement in general.
  2. If we are going to have images showing the item in question perhaps we should show different ones. I would be all for showing a couple of historic models if there are any available.
  3. This is a small edit, it is not that significant but it does add more to the article than the previous image that was here and certainty more than countless reverts. (Your only contributions to this article over the last year have been reverts BTW).

Please stick to discussing content, see WP:CIVIL. Johnuniq (talk) 23:30, 19 July 2011 (UTC)
(e/c) You should self revert your last edit to the article. You currently have 4 reverts within 24 hours: you replaced an existing picture with your own (aka a revert - undoing something a previous editor did), and then you reverted me three times when I removed your picture.
I removed your picture because it does not add much to the article. The article does not need pictures of slight variations; all three pix are finger cuffs instruments. Your picture shows more hand and trees than the instrument itself. The picture is poorly lit (no fill-in flash) and has poor composition. The readout is also small. It's your own picture, so there's a potential WP:COI about you judging the merits of the picture.
The article could use illustrations of how the instrument works: for example, light path, dual wavelengths, and absorbtion plots.

I agree that the edit warring needs to stop. It's silly and pointless.
I don't have strong opinions about the images, but in general I'd rather see more than one, and, for medical devices, I'd rather see pictures by our users than images arranged by manufacturer's marketing departments, even if the users' images have minor technical problems. WhatamIdoing (talk) 23:55, 19 July 2011 (UTC)
I agree, I don't see what is wrong with the image, it's actually quite good quality. Glrx, you didn't really need to revert to begin with, you could have just taken it up with the user on his talk page and left the image in until discussion reached a closure. That Ole Cheesy Dude (Talk to the hand!) 00:03, 20 July 2011 (UTC)
My thoughts on the issue are quite simple:
  1. There are more than just finger oximeters and I believe that the article should show what is available. It should probably also show some historical models. There must be older devices out there that have been photographed. I had a quick gander on flickr for licence suitable ones but nothing interesting came up.
  2. The stock photos used previously could be from anywhere and indeed one of the images of a finger mounted model is a crop of an image removed for copyright violation and the other one is on an OTRS ticket. The image I used is PD and will of course always be.
  3. The reasons given by the reverting user changed with each argument that I made against the reversions. It seemed to me that the user simply wanted some control over the article. This was reinforced by the fact that the only revisions made to this article by said user in the last year were reversions.
Anyway this is pretty much what I said when I added this section yesterday. Sorry about the edit warring, you are right it is very silly indeed. Sometimes one just feels irked into being a dick. My point is made and I'm happy whatever decision is made now :) --UusiAjaja (talk) 23:36, 20 July 2011 (UTC)
