Talk:Hyperventilation syndrome

The
The page used to say the traditional remedy was to breathe into a plastic bag. I changed it since plastic bags are too new for it to be traditional, and every source I have seen says paper. But more to the point, is it safe to put a plastic bag over your mouth and try to breathe? If you're panicking already? Paper bags are both air-permeable (but restrict the air enough that it straightens out your breathing) and stiff enough not to be inhaled. --Andrew 11:45, Apr 16, 2004 (UTC)


 * Granted. The whole page was more of a stub effort anyway.   JFW |  T@lk  11:52, 16 Apr 2004 (UTC)

Metabolic acidosis causes hyperventilation
thats what i have been told, and what i read from Davidson's Principles and Practice in Medicine 21st Edition i'm a 6th year medical student in this article under " Causes " it says " Alkalosis " as a cause of Hyperventilation Syndrome if i was right i hope someone do something about it :) — Preceding unsigned comment added by Amro0od (talk • contribs) 10:48, 4 April 2012 (UTC)

O2/CO2
If the CO2 levels are lower, how is it that The amount of O2 that goes to the brain decreases?


 * An untagged comment but on the same day! I too came across this article while editing the panic attack article. I am at a loss to see how the O2 levels going to the brain diminish. If anything they should increase marginally. Hyperventilation leads to higher O2 levels but only marginally. It is the CO2 that is the main gas that changes dramatically in hyperventilation. This sentence was added by 67.51.99.220 on 29 April 04. Since it is anonymous, unsupported by a reference and does not concord with usual respiratory physiology I have removed it. I have also added some other physiology. --CloudSurfer 04:41, 25 Sep 2004 (UTC)


 * Basically, the reason hyperventilating can lower blood oxygen levels is that breathing is stimulated by high levels of carbon dioxide in the blood. When carbon dioxide levels are low, the respiratory reflex is suppressed. So as soon as someone stops hyperventilating, they'll often start hypoventilating for a while immediately afterwards, until carbon dioxide levels return to normal. By that time their blood oxygen levels will often have dropped significantly below normal. Incidentally, this is why it's dangerous to hyperventilate before swimming or diving -- if you flush enough carbon dioxide out of your system and then hold your breath, you may not realise you're running out of oxygen until a couple of seconds before you lose consciousness. 203.45.6.118 13:31, 12 August 2005 (UTC)


 * People with Chronic Hyperventilation Syndrome have about the same oxygenation in the arterial blood (normal value for haemoglobin saturation is 98%) and too little carbon dioxide in their blood and other tissues. As a result, Chronic Hyperventilation Syndrome or overbreathing reduces oxygenation of vital organs (tissue hypoxia) due to CO2-induced vasoconstriction and the suppressed Bohr effect.

New Section on Epidemiology Is Required
Hi, everybody, Due to overwhelming scientific evidence, this section requires a new section about epidemiological data regarding prevalence of alveolar hypocapnia or hyperventilation in patients with various conditions. Please, consider this table: http://en.wikipedia.org/wiki/User:Artour2006/Prevalence_of_hyperventilation Artour2006 (talk) 16:03, 29 June 2009 (UTC)


 * I don't understand how it fits into this article (which isn't about hyperventilation in general, but about a specific collection of signs and symptoms involving hyperventilation), and overall it seems rather like original research that doesn't belong in Wikipedia. WhatamIdoing (talk) 23:03, 5 July 2009 (UTC)


 * Table as a concept is flawed - its a collection of primary sources synthesised to make for a whole condition (i.e. WP:SYNTHESIS). Hyperventillation syndrome as such does not occur for example as a routine in COPD - they tend to get raised CO2 due to their damaged lungs, and whilst they might breath faster as a result of poor lung function (hyperventillation not being same as hyperventillation syndrome which is an unnecessary need to breath as excessively), their primary problem is not of hyperventillation and they do not end up with abnormally low CO2 levels. Case number cited are pityfully low too - 12 patients with childhood absence seizures does not make for rash asserted implication of "epilepsy" as a whole. Provide a reliable medical secondary source for the table/epidemiology as a whole, and then the table can be reworked. For now removed as WP:NOR. David Ruben Talk 18:59, 25 April 2010 (UTC)


 * Agree that the table is not reliable / encyclopedic at this point and should be removed. Doc James  (talk · contribs · email) 19:22, 25 April 2010 (UTC)

Completely disagree. The page starts with: Hyperventilation syndrome (HVS; also chronic hyperventilation syndrome or CHVS) is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly... Hence, we are talking about alveolar hyperventilation, without any care to blood gases. It is then logical to investigate its prevalence (of prevalence of alveolar hyperventilation) in chronic disosrders so that the condition has a clear connection with real life. Another option is to hide our heads in sand and pretend that the sick breathe normally. As about COPD, there are several studies that proved 100% prevalence of alveolar hyperventilation in COPD. Further studies proved that alveolar hypocapnia destroys lung cells. If they have 25% lungs left, and it is ventilated at 6 L/min at rest (seemingly normal), it is surely equal to 24 l/min for the whole lung. Artour2006 (talk) 23:29, 19 June 2010 (UTC)

The end of hyperventilation 'syndrome'
After reading the following article, I think this whole page should be re-written/scratched.

H K Hornsveld, B Garssen, M J C Fiedeldij Dop, P I van Spiegel, J C J M de Haes (1996). Double-blind placebo-controlled study of the hyperventilation provocation test and the validity of the hyperventilation syndrome Lancet; 348: 154–58

I agree with this. As well as the paper cited above there are others.

Bass C. Hyperventilation syndrome: a chimera?. Journal of  Psychosomatic Research 1997;42(5):421-6.

Troosters T, Verstraete A et al. Physical performance of  patients with numerous psychosomatic complaints suggestive of   hyperventilation. European Respiratory Journal. 14(6):1314-9,  1999.

There are virtually no recent scientific studies of the alleged hyperventilation syndrom and it is almost certainly a mythical disorder.

 * The term "Hyperventilation syndrome" is used by the NHS in the UK (example: https://www.cuh.nhs.uk/patient-information/hyperventilation/ ), and in the US (example https://www.heraldopenaccess.us/openaccess/hyperventilation-syndrome-a-diagnosis-usually-unrecognized ). So probably not a mythical disorder. FrankSier (talk) 10:52, 19 February 2023 (UTC)

Review
Does anyone have access to this ? Doc James (talk · contribs · email) 14:13, 24 January 2011 (UTC)


 * Unfortunately, no. The most recent reviews and in English, I could find and have access to are and . I think it's interesting many reviews are in French. Yobol (talk) 00:45, 25 January 2011 (UTC)

adding others names
this article say that the name is also was termed "cryptotetany" or "spasmophilia"
 * http://www.mgwater.com/clmd.shtml and https://www.tandfonline.com/doi/abs/10.1300/J092v04n02_07
 * https://pdfs.semanticscholar.org/16df/8cf0ca39b3a83d84a5c97b6daafbd19a4c0a.pdf — Preceding unsigned comment added by Vatadoshu (talk • contribs) 21:57, 12 September 2019 (UTC)

and this say that spasmophiilia as also another name that is latent tetany :
 * https://www.ncbi.nlm.nih.gov/pubmed/14593759 '" latent tetany or spasmophilia "'
 * https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5047258/
 * http://www.mgwater.com/clmd.shtml

the wikipedia french link is for "spasmophilie"

i think you should add 3 names: "latent tetany", spasmophilia and cryptotetany since there are ncbi study on each.

--Vatadoshufrench 21:00, 12 September 2019 (UTC)

and this name too

"central neuronal  hyper  excitability  syndrome" ou NHS cf https://www.researchgate.net/publication/320599116_Spasmophilia_in_the_Cardiological_Outpatient_Department_A_Retrospective_Study_of_228_Sub-saharan_Africans_over_5_Years "Spasmophilia also  called  latent  tetany  and  recently  referred  to  as  the central  neuronal  hyper  excitability  syndrome  (NHS) " Vatadoshufrench 19:50, 13 September 2019 (UTC)
