Talk:Valsalva maneuver

message: 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.

thread_title:  Function of the Diaphragm 

message: Is there any documentation on the Valsalva meaneuver where the air is expelled through your tear-duct?  This happens to me.
:Yes : http://www.emedicine.com/OPH/topic592.htm  Specifically, if the valve of Hasner and valve of Rosenmüller in the nasolacrimal duct are missing increased pressure in the nasal cavity (as with nose-blowing or the Valsalva maneuver) an cause retrograde passage of air or fluids through the nasolacrimal duct onto the eye.
:In an episode of _Ripley's Believe it or Not_ Jim Cichon was documented as the world record holder for squirting milk from his tear duct.
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? --Wikipediatastic 10:57, 17 March 2006 (UTC)

thread_title:  Air expelled through eye 

message: 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)

thread_title: Abuse of this Mechanism? 

message: 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)

thread_title:  Removed Psychiatic applications 

message: 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)

message: 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)
replies: text: It is mentioned briefly in the  Valsalva retinopathy section, but the early sentence "It is also often used to aid in the expulsion of feces from the rectum during a bowel movement" was removed as "redundant" by this edit in February 2006. It was unsourced, so liable to be removed. I would suggest finding a reliable source that describes this application and use it to expand the article. --RexxS (talk) 18:10, 30 May 2010 (UTC)
replies: text: According to Barry B. White, the main causes of Valsalva Maneuver are: 1. Straining at stool due to constipation. 2. Straining to urinate. 3. Straining to raise up in bed or to get in or out of bed... See Barry B. White, Therapy in Acute Coronary Care (1971), p.65. According to Sharon Mantik Lewis, Margaret McLean Heitkemper and Shannon Ruff Dirksen, “Valsalva maneuver … occurs during straining to pass a hardened stool.” “If defecation is suppressed over long periods, problems can occur, such as constipation or stool impaction. Defecation can be facilitated by the Valsalva maneuver. This maneuver involves contraction of the chest muscles on a closed glottis with simultaneous contraction of the abdominal muscles.” See Sharon Mantik Lewis, Margaret McLean Heitkemper, Shannon Ruff Dirksen, eds., Medical-Surgical Nursing: Assessment and Management of Clinical Problems, 6th edition, Volume 2 (2004), p.951. Gladys Nite and Frank Neal Willis write that it has been pointed out “that the danger of a Valsalva maneuver is increased by constipation.” See Gladys Nite and Frank Neal Willis, The Coronary Patient: Hospital Care and Rehabilitation (1964), p.164.

thread_title:  When defecating 

message: 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.
Greggor88 (talk) 00:36, 19 June 2012 (UTC)
replies: text: I agree that the modified maneuver (against a closed glottis) is used in those three exercises of powerlifting, and would add it is also used in both lifts of Olympic weightlifting. I suspect it is also used in other sports, such as discus throwing. Perhaps the groan of (particularly female) tennis players indicates they do this too. --SpecMade (talk) 17:22, 3 October 2013 (UTC)
replies: text:  I agree that it should be included. It would be very arguable that this is actually the most common (and natural) instance of the Valsalva manuever.  — Preceding unsigned comment added by 152.19.172.74 (talk) 21:56, 4 March 2014 (UTC)

thread_title:  Valsalva Maneuver And Weightlifting 

message: 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)
thread_title:  No mention of Vagus Nerve Stimulation? 

message: The  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
I've added a  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)
