abdominal thrusts

Thoracic surgeon and medical researcher Henry Heimlich, noted for promulgating abdominal thrusts, claimed that back slaps were proven to cause death by lodging foreign objects into the windpipe.{{cite news|url=https://www.nytimes.com/2009/02/06/opinion/l06heimlich.html|newspaper=The New York Times|title=Heimlich, on the maneuver|access-date=February 7, 2009 | date=February 6, 2009}} A 1982 Yale study by Day, DuBois, and Crelin that persuaded the American Heart Association to stop recommending back blows for dealing with choking was partially funded by Heimlich's own foundation.{{Cite news|url=http://pittmed.health.pitt.edu/AUG_2005/life_jackets.pdf|publisher=University of Pittsburgh Medical School|title=Lifejackets on Ice (August 2005)|access-date=May 24, 2009}} According to Dr. Roger White of the Mayo Clinic and American Heart Association (AHA), “There was never any science here. Heimlich overpowered science all along the way with his slick tactics and intimidation, and everyone, including us at the AHA, caved in.”{{Cite news|url=https://books.google.com/books?id=rcMqOFGzb_oC&q=a+new+maneuver+mills-senn&pg=PA88|publisher=Cincinnati Magazine|title=A New Maneuver (August 2005)|author=Pamela Mills-Senn|date=April 2007|access-date=December 22, 2013}}

Henry Heimlich also promoted abdominal thrusts as a treatment for drowning{{Cite web |url=http://www.heimlichinstitute.org/drowning.php |title=Heimlich Institute on rescuing drowning victims |access-date=June 5, 2007 |archive-date=January 24, 2008 |archive-url=https://web.archive.org/web/20080124163011/http://www.heimlichinstitute.org/drowning.php |url-status=dead }} and asthma{{Cite web |url=http://www.heimlichinstitute.org/asthma.php |title=Heimlich Institute on rescuing asthma victims |access-date=June 5, 2007 |archive-date=March 14, 2011 |archive-url=https://web.archive.org/web/20110314151117/http://www.heimlichinstitute.org/asthma.php |url-status=dead }} attacks. The Red Cross now contests those claims. The Heimlich Institute has stopped advocating on their website for the Heimlich maneuver to be used as a first aid measure for drowning victims. Heimlich's son, Peter M. Heimlich, alleges that in August 1974 his father published the first of a series of fraudulent case reports in order to promote the use of abdominal thrusts for near-drowning rescue.{{Cite web|url=http://www.medfraud.info|title=Outmaneuvered – How We Busted the Heimlich Medical Frauds |first=Peter M |last=Heimlich |access-date=June 22, 2007}}[http://medfraud.info/TimesLeader_8-22-07.html Heimlich's son cites Dallas case in dispute.] Wilkes-Barre News, August 22, 2007 The 2005 drowning rescue guidelines of the American Heart Association{{cite journal|date=November 25, 2005|title=Part 10.3: Drowning|journal=Circulation|volume=112|issue=24|pages=133–135|doi=10.1161/CIRCULATIONAHA.105.166565|doi-access=free}} did not include citations of Heimlich's work, and warned against the use of the Heimlich maneuver for drowning rescue as unproven and dangerous, due to its risk of vomiting leading to aspiration.

In May 2016, Henry Heimlich, then age 96, claimed to have personally used the maneuver to save the life of a fellow resident at his retirement home in Cincinnati. It was alleged to be either the first or second time Heimlich himself used his namesake maneuver to save the life of someone in a non-simulated choking situation.{{cite web|url=https://www.theguardian.com/us-news/2016/may/27/dr-heimlich-performs-heimlich-manoeuvre-for-first-time-aged-96|title=Dr Henry Heimlich uses Heimlich maneuver to save a life at 96|first=Joanna|last=Walters|website=TheGuardian.com|date=May 27, 2016}} According to Heimlich's son, Peter M.

A choking victim is usually unable to speak, and may not be able to make much sound. A universal sign of choking has been designated as a silent indication from a person who is unable to breathe, and consists of placing both hands on one's own throat while trying to attract the attention of others who might help.{{Cite web |last=Rivera |first=Anna |date=2025-02-06 |title=Dysphagia: Understanding Choking and Swallowing Problems in Elderly Adults |url=https://willnice.net/choking-prevention/what-causes-choking-in-older-adults/ |access-date=2025-03-18 |website=Willnice |language=en-US}}{{cite web|title=Choking first aid – adult or child over 1 year – series |url=https://medlineplus.gov/ency/presentations/100222_1.htm |website=MedlinePlus |publisher=National Institutes of Health |access-date=March 11, 2016 }}

Both the American Red Cross and UK National Health Service (NHS) advise that for a first attempt, a rescuer should encourage the patient to expel the obstruction by coughing. As a second measure, the rescuer should deliver five slaps to the back after bending the patient forward. Abdominal thrusts are recommended only if these methods fail.

The American Red Cross, the NHS, the European Resuscitation Council and the Mayo Clinic recommend a repeating cycle of five back slaps and five abdominal thrusts.{{cite web|title=STEP 3: Be Informed – Conscious Choking {{!}} Be Red Cross Ready|url=http://www.redcross.org/flash/brr/English-html/conscious-choking.asp|website=www.redcross.org|access-date=December 4, 2017}}{{cite web|url=https://www.nhs.uk/common-health-questions/accidents-first-aid-and-treatments/what-should-i-do-if-someone-is-choking|title=What should I do if someone is choking?

In contrast to the prevailing American and European advice, the Australian Resuscitation Council recommends chest thrusts instead of abdominal thrusts.

To perform a Heimlich maneuver, a rescuer stands behind an upright patient, using the hands to exert forceful pressure on the bottom of the diaphragm.{{Cite web |title=How To Do the Heimlich Maneuver |url=https://my.clevelandclinic.org/health/treatments/21675-heimlich-maneuver |archive-url=http://web.archive.org/web/20250303235904/https://my.clevelandclinic.org/health/treatments/21675-heimlich-maneuver |archive-date=2025-03-03 |access-date=2025-03-18 |website=Cleveland Clinic |language=en}} As an example, WebMD recommends making a fist with one hand and grasping the fist with the other in order to press with both just above the patient's navel. This compresses the lungs and exerts pressure on any object lodged in the trachea in an effort to expel it. The pressure amounts to an artificially induced cough. To assist a larger person, more force may be needed.{{Cite web |title=Heimlich Maneuver for Adults and Children Older Than 1 Year - Topic Overview |url=http://firstaid.webmd.com/tc/heimlich-maneuver-for-adults-and-children-older-than-1-year-topic-overview |archive-url=https://web.archive.org/web/20160306091727/http://www.webmd.com/first-aid/tc/heimlich-maneuver-for-adults-and-children-older-than-1-year-topic-overview |archive-date=March 6, 2016 |website=WebMD}} The Mayo Clinic recommends the same placement of fist and hand, with upward thrusts as if the rescuer is attempting to lift the victim.

If the victim cannot receive pressure on the abdomen (for example, in case of pregnancy or excessive obesity), chest thrusts are advised.{{Cite web|url=https://ehs.okstate.edu/site-files/docs/cpr-and-choking-5-min-safety-talk.pdf/|title=Choking Safety Talk|website=Oklahoma State University|url-status=live|archive-url=https://web.archive.org/web/20200130145512/https://ehs.okstate.edu/site-files/docs/cpr-and-choking-5-min-safety-talk.pdf/|archive-date=2020-01-30}} These are applied on the lower half of the chest bone, but not in the very endpoint (the xiphoid process, which could be broken).

For victims who are not in an upright position, The American National Institutes of Health recommends positioning the victim on the back, then straddling the torso and employing chest thrusts.{{cite web|title=Abdominal thrusts|url=https://www.nlm.nih.gov/medlineplus/ency/article/000047.htm|website=MedlinePlus|publisher=National Institutes of Health|access-date=March 11, 2016}}

It is possible for conscious choking victims to perform the procedure on themselves, without assistance.{{cite web|title=Heimlich maneuver on self |url=https://www.nlm.nih.gov/medlineplus/ency/article/001983.htm|website=MedlinePlus |publisher=National Institutes of Health|access-date=March 11, 2016}}

Because of the forceful nature of the procedure, even when performed correctly, abdominal thrusts can injure the victim. Bruising to the abdomen is highly likely and more serious injuries can occur, including fracture of the xiphoid process or ribs.{{Cite web|url=http://www.health.discovery.com/encyclopedias/illnesses.html?article=671 |title=Heimlich maneuver on self |publisher=Discovery Channel |last=Broomfield |first=James |date=January 1, 2007 |access-date=June 15, 2007}} The NHS recommends that victims subjected to abdominal thrusts should seek medical attention after the event.

Researchers at Royal Brompton Hospital have demonstrated that levels of intrathoracic pressures (50–60 cmH₂O) exerted by inward abdominal thrusts are similar to those produced when the force is directed both inward and upward. The researchers argue that this may be easier to perform with less concern for injury to the rib cage or upper abdominal organs. Self-administered abdominal thrusts by study participants produced similar pressures to those generated by administering first aid. The highest pressures were produced by participants performing an abdominal thrust by pressing onto the back of a chair (115 cmH₂O).{{Cite journal |date=April 5, 2017 |title=Choking on a foreign body: a physiological study of the effectiveness of abdominal thrust manoeuvres to increase thoracic pressure |url= |journal=Thorax |language=en |volume=72 |issue=6 |pages=576–578 |doi=10.1136/thoraxjnl-2016-209540 |issn=0040-6376 |pmc=5520267 |pmid=28404809 |last1=Pavitt |first1=Matthew J. |last2=Swanton |first2=Laura L. |last3=Hind |first3=Matthew |last4=Apps |first4=Michael |last5=Polkey |first5=Michael I. |last6=Green |first6=Malcolm |last7=Hopkinson |first7=Nicholas S. }}{{Cite news|url=https://www.telegraph.co.uk/science/2017/04/12/perform-heimlich-manoeuvre-yes-just-effective/|title=How to perform the Heimlich manoeuvre on yourself (and yes, it's just as effective)|work=The Telegraph|access-date=April 13, 2017|language=en-GB}}
