How to prevent choking: The safe and easy way

How to prevent choking: The safe and easy wayIn 1972, a doctor from Cincinnati read a story about choking. At the time, choking was the sixth leading cause of accidental death. These statistics inspired the doctor to devise a simple way to prevent these deaths from happening. The procedure became known as the Heimlich manoeuvre.

The Heimlich manoeuvre works by creating an artificial cough. By pushing on the diaphragm, the manoeuvre forces air out of the lungs and up through the throat, forcing a trapped object out.

Fast facts on the Heimlich manoeuvre:

  • When a person chokes, they cannot inhale or exhale air, which is why it is not possible to cough an object out during a choking episode.
  • Until the 1970s, there was no widely accepted research-based strategy for managing choking.
  • People should only ever carry out the Heimlich manoeuvre on someone who is choking.

How to do the Heimlich manoeuvre

There are four ways to perform the Heimlich manoeuvre, depending on the age and needs of the choking person. The underlying action with each approach is the same: using the muscles of the diaphragm to force the object out of the throat.

Conscious adult or child

If the adult or child over the age of 1 is conscious but cannot speak, cough, or breathe, perform the Heimlich manoeuvre immediately, following these steps:

  • Stand behind the person who is choking, arms wrapped around their waist.
  • Make one hand into a fist. Position the thumb side of the fist against the person’s stomach, below their ribs and above the belly button. It is possible to feel the diaphragm muscle.
  • Put the other hand over the fist and push into this muscle with a rapid, forceful, upward thrust.
  • Continue abdominal thrusts until the object comes out.

Unconscious adult or child

If the child or adult is unconscious or cannot sit or stand, perform these steps:

  • Position the choking person flat on their back.
  • Sit on the person’s thighs, facing toward them
  • Place one hand on top of the other and then position the heel of the hand over their diaphragm, just below their rib cage and above their belly button.
  • Lean onto the hands, pushing up and in.
  • Continue repeating thrusts until the object is coughed out.

Performing Heimlich on yourself

  • If you choke while alone, or when there is no one to help, do the following:
  • Make a fist, and with thumbs pointing inward, position the fist against the diaphragm – under the rib cage and above the navel.
  • Push in and up until the object is expelled.
  • If unable to do this or it does not work lean over a solid object, such as a counter or chair. Position the edge at the diaphragm to push in and up. Move slightly forward and backward to produce thrusts.
  • Repeat until the object is dislodged.

Infants under 1 year

In infants under 1 year of age, follow these steps:

  • Position the baby face down on the forearm, ensuring the baby’s head is lower than their chest.
  • With the forearm resting on the thigh, support the baby’s head with the hand.
  • Make sure the baby’s mouth and nose are not covered
  • Use the heel of the other hand to smack the baby’s back in between the shoulder blades four times. Repeat until the object comes out.
  • If this fails, turn the baby over. Position two fingers in the centre of the baby’s chest, between the nipples. Forcefully push down four times to a depth of about 1 inch. Repeat until the object comes out.

The history of the Heimlich manoeuvre

Henry Heimlich, a thoracic surgeon, read about the epidemic of choking deaths in restaurants.

He discovered that the American Red Cross recommended slapping choking victims on the back. But there was not much evidence to support this strategy.

Heimlich discovered that by pressing on the diaphragm in an upward direction, the lungs could push enough air out to expel the object. This simple procedure became the Heimlich manoeuvre and within a few years, organizations such as the Red Cross began recommending it as the best strategy for saving the lives of people who were choking.

Practicing the Heimlich manoeuvre

It is not possible carry out the Heimlich manoeuvre on someone who is not choking.

However, because the technique involves pushing on the diaphragm, it is possible for a person to familiarize themselves with the procedure by locating their diaphragm and feeling for a thick band of muscle just underneath the rib cage.

Pushing forcefully on this muscle should produce a jarring sensation that pushes air out of the lungs.

This can bolster confidence in the event of an actual choking episode.

Heimlich manoeuvre safety

If a person can cough, talk, gag, or breathe, they are not choking. Wait for them to cough the item out. Only begin the Heimlich manoeuvre if the person is unable to dislodge the object and cannot breathe.

The Heimlich manoeuvre does not save drowning victims, and will not save people from other emergencies, such as cardiac arrest or a seizure.


Sometimes the Heimlich manoeuvre fails, either because the item is too deeply lodged in the throat or because a person does not do the manoeuvre correctly. For this reason, always call 911 immediately when someone is choking.

If two people are available, one should call 911 while the other performs the Heimlich manoeuvre. This maximizes the chance of survival even when Heimlich does not work.
