Talk:Hypercapnia

Merge CO2 retention into this article
I've suggested a merge at Talk:CO₂ retention:

Should CO2 retention be merged into Hypercapnia? I know that the terms are not identical, but it is one of the principal causes of hypercapnia. Neither article is large and it would seem to be sensible to collect related information together. For what it's worth, Carbon dioxide retention is already a redirect to Hypercapnia.

Any comments welcome. --RexxS (talk) 17:47, 4 January 2010 (UTC)


 * I agree. In the long run, they are basically the same thing.  Mike   Allen  06:11, 24 April 2010 (UTC)


 * I also agree, CO2 retention should be a subsection of Hypercapnia. > Merge and redirect. I will get to it when I have more reliable internet again. &bull; &bull; &bull; Peter (Southwood) (talk): 03:06, 17 December 2013 (UTC)

Categories
As this is a condition, not a sign or symptom, I've changed the category from Category:Symptoms and signs: Respiratory system to Category:Respiratory diseases for want of anything more specific. --RexxS (talk) 15:26, 30 July 2011 (UTC)

Proposed merge of Normocapnia
doesn't seem to justify an article of its own Rathfelder (talk) 21:07, 6 September 2015 (UTC)

 * Oppose merge. There's plenty of detail that can be added to normocapnia.  Like what normal levels are, how the body maintains those levels, how they are tested, and so on. But more importantly, good health should be presented in articles on good health rather than merely as subtopics of illnesses or abnormalities. The Transhumanist 19:09, 16 January 2016 (UTC)

B-Class review
Looks OK. Promoting to B-class for WikiProject Scuba. &bull; &bull; &bull; Peter (Southwood) (talk): 19:12, 18 December 2016 (UTC)

Cognition effects at low concentrations
In the Tolerance section there's table describing major limitations as a function of inspired CO2 %. I propose adding a minor limitation column which describes some of the cognitive effects observed in the following studies: Currently this article gives the false impression that CO2 has essentially no effect at sub-2500 ppm.

 * Those are both primary sources – single studies – one from 2012 and the other from 2016. Ideally, we should be using secondary sources (reviews, meta-analyses, etc.) to support any biomedical claim, such as the effect of CO2 on decision-making performance and cognitive function, as explained at WP:MEDRS. --RexxS (talk) 16:45, 26 January 2018 (UTC)

Original research
I have removed this:


 * The spelling "hypercapnea" is occasionally seen in published medical articles (44 results in a PubMed search in 2016), but it is not entered in major dictionaries and is not tied to any etymology that involves the -pnea suffix. It is a misspelling by writers who misunderstand that the word hypercapnia does not end in the same suffix that apnea does.

Can be reinserted in altered form if someone has a source. JFW &#124; T@lk  07:04, 15 August 2019 (UTC)

"Tolerance" table
I have removed the following table, which was in the "Diagnosis" section but without any logical reason for this. I suspect it was inserted as part of the diving content.

Happy to reinsert with some degree of context. JFW &#124; T@lk  14:22, 16 August 2019 (UTC)

"Facemasks cause hypercapnia" fantasy
I don't think Wikipedia should be in the business of giving space in articles to debunking every bit of self-evidently nonsensical bs that appears on social media. But since this conspiracy theory cites the Wikipedia article, it is probably useful to have a talk page mention of it, in case someone takes it seriously This BBC fact check page explains why it is nonsense: Coronavirus: 'Deadly masks' claims debunked. --John Maynard Friedman (talk) 08:16, 21 June 2020 (UTC)
