The article says that the Valsalva Maneuver is used for a bowel movement. This is only the case when using the sitting position (on a conventional toilet). Two-thirds of the world use squat toilets and avoid the deleterious effects of this maneuver -- both for defecation and for childbirth.
One example is hinted at in the article: "This maneuver is also sometimes used to discover an inguinal hernia in men." The daily use of this maneuver for excretion is the main reason why 700,000 hernia repair operations are performed each year in the U.S. See this link [1] to verify the number.
This link http://naturesplatform.com/health_benefits.html explains how sitting toilets force people to injure themselves thru the unnatural use of the Valsalva Maneuver, and how squatting would prevent much needless suffering.

Getting back to the Valsalva Maneuver, you can easily prove to yourself that it is not required when squatting. Even if you don't buy all the implications for prevention and treatment of disease, the article needs to be corrected so it does not imply that the Valsalva Maneuver is involved in natural defecation. -- Jonathan108 16:48, 4 October 2005 (UTC)
This article incorrectly describes the function of the diaphragm. The diaphragm, like all muscles, can only contract in one direction. Muscles pull, they cannot push. That said, when the diaphragm contracts, it pulls down in the thoracic cavity causing inhalation of air into the lungs by creating a negative pressure (via cavity expansion). The diaphragm does NOT contract to cause exhalation of air.

Is there any documentation on the Valsalva meaneuver where the air is expelled through your tear-duct? This happens to me.
This article has been referenced by a Slate magazine article. I think there is a template that can be added to the top of this page to say that but am quite new so can't find it. Any ideas? --

When viewed just now, the image in this article showed just the Wiki sample default image. Also, a few sentences below that is the sentence "Blood pressure (systolic and diastolic) and pulse rate during a normal response to Valsalva’s manoever." which is missing a key word... the longer description described increases and decreases, and my non-medical self can't figure out which should go in the sentence.

I remember when I was in school we once did this "trick," where you stood against a wall and held your breath, then someone applied pressure to your chest and would then suddenly stop pressing. Which made you fade. Does that work in the same way as the Valsalva maneuver? 83.118.38.37 00:02, 3 November 2006 (UTC)
I'm removing the following unsourced text:
It is important to note that the maneuver is only helpful during a descent, either in the air or water. During an ascent, the increasing pressure in the middle ear relative to the decreasing ambient pressure will generally escape through the Eustachian tubes without assistance. In any case, attempting to force additional air into an already over-pressurized middle ear is almost certainly a bad idea, and potentially dangerous.
I'm not sure this is true. Even if the middle ear is overpressurized, it makes sense to me that the V maneuver, by opening the Eustachian tubes, might ultimately allow air to flow out of the middle ear after an initial further increase in pressure. My own experience and some Googling seems to support this. (Most websites refer to the V maneuver as a way to equalize pressure in general, and don't say it's only for cases where pressure is too low.) -- Allen 04:12, 19 May 2007 (UTC)

Certified PADI divemaster here, i can confirm that the manoeuver is mainly used during descent but can be and is definitely used during ascent too - especially if accompanied by hyperextending the neck towards the back and/or wiggling the head to one side and the other while doing so - to ease the exit of air from the middle ear. Since this latter use during ascent requires more care to avoid damaging the inner ear the procedure is rarely recommended for beginner divers, that usually perform shallower and shorter dives. — Preceding unsigned comment added by 5.99.125.86 ( talk) 22:37, 14 October 2015 (UTC)
I removed the following because it seemed completely nonsensical

When performing the Valsalva maneuver, neither I nor other fliers I know do it against closed lips. Everyone I know does it by closing off the back of the mouth with the tongue. This is less fatiguing if you have to do it many times, gives more direct pressure, and also doesn't look goofy. Shawn D. ( talk) 16:32, 18 November 2007 (UTC)
Chrishibbard7 ( talk) 18:39, 6 January 2009 (UTC) There are caveats to self-treatment via Valsalva maneuver: it does increase blood leakage between the two upper chambers of the heart for anyone with a PFO, currently estimated as 10-30% of healthy humans alive today. I was told to use this method during a PFO test to increase surgically aerated blood between chambers in order to determine the size of the inter-chamber opening. I was warned by the tech performing the test not to purposely execute this maneuver again and also warned not to 'strain too hard' during BM for the same reason.
Also, moving the jaw forward and down or simply downward in order to open eaustacian tubes to relieve ear pressure can contribute to TMJ syndrome (pain in the TurboMandibular Joints).
While this article is well-composed, it has no sources or references. Wuapinmon ( talk) 22:46, 10 February 2008 (UTC)
Am I the only person who needs not yawn or swallow, but can simply conciously open those tubes? to 'click one's ears' ... I've been able to since I was little. —Preceding unsigned comment added by 75.73.70.113 ( talk) 02:38, 5 April 2009 (UTC)
I see no mention in the article of this applied in relation to defecation, i.e. to assist or trigger bowel movement. Reading the topmost post on this page I gather that the article in a previous state has discussed this. So why doesn't it anymore? __ meco ( talk) 15:25, 30 May 2010 (UTC)
The Valsalva Maneuver (modified version against a closed glottis) is frequently used in weightlifting to stabilize the core during exercises such as the Squat, Deadlift, and Bench Press. How can we best incorporate this into the article. It seems like an extraneous use of the Maneuver, since it doesn't rely on any of the four physiological responses currently in the article.

I believe that performing the valsalva maneuver causes the stimulation of the Vagus nerve. If so, shouldn't there be at least a mention of (if not a section about) the Vagus nerve? ( talk · contribs · email) Maestroso simplo ( talk) 04:01, 10 February 2015 (UTC)
Not that there isn't one to be found but so far I can’t find a reliable source that states that the Valsalva maneuver is both closing the glottis and is also closing the nose and mouth. One is used to raise blood pressure in the body and the other is to clear the ears. Are both actually “the Valsalva maneuver” or has one been confused with the other? Unconventional2 ( talk) 18:35, 14 March 2016 (UTC)
The § Heart section presently concludes with the following paragraph:
BP rises at onset of straining-because the increased intrathoracic pressure (ITP) is added to the pressure in the aorta. It then falls because the ITP compresses the veins, decreasing the venous return and cardiac output. This inhibits the baroreceptors causing tachycardia and a rise in peripheral vascular resistance (PVR). When the glottis is opened and the ITP returns to normal, cardiac output is restored but the peripheral vessels are constricted. The blood pressure therefore rises above normal and this stimulated the baroreceptors, causing bradycardia and a drop in BP to normal level - Ganong citation needed
I've added a {{cn}} tag behind the unexplained word "Ganong". If you hover over that, you'll see my reason pop up. Perhaps there's a form of that template that lets one state a reason more simply, not needing the work-around I've used here, viz., replacing space by underscores? For all I know, the present text could be an extended quotation without proper attribution. Whatever the case, we can do better.
Anyway, I'd never encountered "Ganong" before, and a quick Google turned up "Ganong's Review of Medical Physiology", a textbook now in its 25th edition (2015), originally written by William Francis Ganong Jr. So, after editing the stub-class article on the author, I've now returned here. Can somebody with access to (a reasonably current edition of) "Ganong", or some other reliable source, improve this para of the article, with citation? yoyo ( talk) 03:26, 23 July 2018 (UTC)
