Talk:Pulse oximetry

message: I find the term 'red infrared' a bit misleading and unaccurate. I would rather use 'red + infrared', or, more appropiately, '(a beam) comprised of red and infrared wavelengths'. However I don't dare to edit it (I'm an electronic engineer -- i.e. a layman in medicine).

message: I think that these two articles cover enough of the same ground that the devices and their use can safely be merged into a single article.  WhatamIdoing (talk) 22:56, 23 December 2008 (UTC)
replies: text: Agree, or at least move all the generic pulse oximerty information out of the pulse oximeter article and leave it as a description of the device per se. - Draeco (talk) 15:32, 13 March 2009 (UTC)

text: Disagree, The two articles should cover different material.  Whether or not they currently have the same information is immaterial.  The question is: is there a difference in information that could or should be in the two separate articles.  The answer is yes, one covering the technology, state of the art, physics, etc. and a second one outlining the current, historical, and future products that take advantage of these scientific concepts.  —Preceding unsigned comment added by 150.148.0.27 (talk) 18:40, 16 July 2009 (UTC)

text: Disagree,Each article stands on its own, and contains valuable information that would be lost if a merge were to occur. A very emphatic disagree here. Ronk01 (talk) 01:09, 5 April 2010 (UTC)
replies: text: Why do you think that a merge cause us to lose any information at all?  The point of a merge is to put all the information on one page, not to delete half of it.  WhatamIdoing (talk) 20:40, 1 December 2010 (UTC)

text: Disagree, Pulse oximeter clearly deserves a page of its own as pulse oximetry is too broad a category for pulse oximeter to be merged.  Jjeong12 (talk) 22:11, 20 June 2010 (UTC)

text: Agree' Because a pulse oximeter has the sole purpose of calculating oxigenation it is logical that of the blood by indirect observation.  To reinforce this ABG's (arterial blood gases) are explained and how they are tested are both included in a single article. So for consistency the article here should explain Pulse Oximetry values how they are calculated, benefits and disadvantages of each and the method of testing in the same article.  This reduces repetitive content between articles and gives a concise definition of the element tested, how the value is calculated, and the method of testing.  wizbang_fl 04:27, 18 September 2020 (UTC)

text: Agree. Having two articles with almost the same name and subject is very confusing, and gives the impression that information is missing if you don't realize that it is in the other article. Dirac66 (talk) 21:04, 26 November 2010 (UTC)

text: Agreefor the merge. Whereas some day there may be enough contents to justify two articles, as of today 90% of the contents is shared between them both!--MarmotteiNoZ 00:09, 16 June 2011 (UTC)

text: Agree To merging pulse oximeter to this article. They cover similar ground and both articles reference each other's content quite often so merging would remove quite a bit of duplicate content. So, I say go ahead with the merge.--Lead holder (talk) 23:22, 7 August 2011 (UTC)

text: Agree to merging: there is still a large degree of overlap in content between the two articles, and hence a significant risk of divergence or inconsistency. Pulse oximeters would be a sensible section of a broader Pulse oximetry article. Docben (talk) 15:07, 2 December 2011 (UTC)
thread_title:  Merge proposal 

message: I'm not knowledgeable enough to edit the main page, however I would like to bring this to the attention to someone who may choose to do so. Advancements in the device now allow for better measurement to help detect anemia. I'm not sure the specifics of the advancement, or the full reach the improvements have on its capabilities. Hopefully someone can update this to reflect that information.

thread_title:  poor explanation 

message: Not sure if this is the correct way to comment here, but wanted to point out that the "correct position" photo (blue remote pulse oximetry sensor on patient finger tip) appears to be incorrect. Typically the lead wire is on the same side as the red/IR LEDs, which should be placed on TOP of the patient's finger tip above the fingernail. This link http://www.infiniti.se/upload/Bruksanvisningar/Masimo/UM_EN_RAD8_LAB5303B.pdf.pdf to the manufacturer documentation for a Masimo pulse oximter with remote sensor shows the correct positioning on page 1-5. This positioning is also evidenced in the topmost photo of the setup used for sleep monitoring (wrist oximeter with remote sensor). (I'm an RN and use pulse oximeters every day). - DawL VuDu DawL (talk) 22:55, 22 June 2013 (UTC)

message: Does the p in SpO2 really stand for peripheral?  I would have guessed it stood for 'pulse oximeter'.   I would assume SaO2 is typically measured (or at least calculated) from peripheral arterial blood on ABGs, which makes the "peripheral" designation of SpO2 curious.  Maybe this term is from the old 1970s non-"pulse" oximeters that worked on fingers in an attempt to estimate the SaO2.

message: Wikipedia now says:
"Research has suggested that error rates in common pulse oximeter devices may be higher for adults with dark skin color, leading to claims of encoding systemic racism in countries with multi-racial populations such as the United States".
If this is racism, why black scientists haven't created any solution to this?

message: I’m curious why in the history section no mention is made of HP’s pulse oximeters which were quite common (if not dominant and the “gold standard” for comparison in the 70s and 80s).  There were other mfrs, too.  
Specifically, the HP 47201A, described here:  
https://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1976-10.pdf
If you go out to PubMed, you’ll find plenty of articles comparing the accuracy of various PulseOxes, and the HP is almost always in there.

West, et al., “Dynamic in vivo response characteristics of three oximeters: Hewlett-Packard 47201A, Biox III, and Nellcor N-100” doi:%2010.1093/sleep/10.3.263
Seems like this article was sort of crafted from a recent summary somewhere else.
