Overview, Causes, & Risk Factors
Choking in a conscious adult may occur when the upper airway, usually thethroat or wind pipe, is blocked by an object or irritation.
What are the causes and risks of the injury?
Choking is more likely if a person:
- swallows large, poorly chewed pieces of food
- drinks too much alcohol
- wears poorly fitting dentures
- talks or laughs while eating
Symptoms & Signs
What are the signs and symptoms of the injury?
Signs and symptoms of choking in a conscious adult include:
- difficulty breathing or lack of breathing
- inability to move air in or out of the lungs through the mouth or nose
- face and extremities turning blue
- clutching the throat or chest
If the choking episode is left untreated, unconsciousness or death may follow.
Diagnosis & Tests
How is the injury recognized?
A choking person will usually grab his or her throat or chest. He or she willappear to be distressed and may panic. The person’s mouth will be open, but heor she will not be able to speak, breathe, or cough.
Prevention & Expectations
What can be done to prevent the injury?
In many cases, choking can be prevented by:
- cutting food into small pieces and chewing slowly
- avoiding laughing and talking while chewing
- drinking alcohol only inmoderation
- wear properly fitting dentures
Treatment & Monitoring
What are the treatments for the injury?
Without oxygen, the brain can begin to die within 4 to 6 minutes. Rapid firstaid for choking can save a life. The best way to help a conscious adult who ischoking is by using the Heimlich maneuver. The procedure is done by causing anartificial cough to expel the object from the airway.
This Heimlich maneuver should not be done unless the person cannot breathe oris turning blue and is definitely choking. The Heimlich maneuver can be donewith the person standing, sitting, or lying down. It may be necessary to repeatthe procedure many times.
Performing the Heimlich maneuver with the person sitting or standing
- Stand behind the person with arms wrapped around the waist.
- Make a fist with one hand.
- Place the thumb side of the fist against the person’s abdomen just abovethe navel but well below the breastbone.
- Grasp the fist with the other hand and press the fist into the person’sabdomen with a quick upward thrust.
- Give up to 5 upward thrusts. Repeat until the object pops out or the person becomes unconscious.
- Each thrust should be a separate and distinct movement.
Performing the Heimlich maneuver with the person lying down
- Place the person face up.
- While kneeling, straddle the person’s thighs. Place the heel of one handagainst the person’s abdomen in the middle, slightly above the navel and wellbelow the breastbone.
- Place the second hand directly on top of the first.
- Press the abdomen with a quick upper thrust.
Performing the Heimlich maneuver on an obese person or pregnantwoman
- Stand behind the person with arms directly under the person’s armpits andcircle the chest.
- Place the thumb side of the fist in the middle of the person’s breastbone,taking care to avoid the xiphoid process. The xiphoid process is at the lowerend of the breastbone.
- Grab the fist with the other hand and perform backward thrusts until theobject pops out or the person becomes unconscious.
Performing the Heimlich maneuver on oneself
- make a fist with one hand
- place the thumb side on the abdomen above the navel and well below thebreastbone
- grasp the fist with the other hand and press inward and upward with a quickmotion
If these steps don’t work, a person should quickly lean over a firm surface,such as the back of a chair, side of a table, or porch railing. Several thrustsmay be needed to clear the airway.
Do not try to remove an object from a conscious person’s mouth. This could pushthe object further into the throat.
If the person becomes unconscious, begin first aid for choking in the unconscious adult.
What are the side effects of the treatments?
The Heimlich maneuver can cause vomiting, injuries to internal organs, or broken ribs. Vomiting can be aproblem if the vomited material is caught in the airway and inhaled into thelungs.
What happens after treatment for the injury?
It is important for a person who has choked to obtain medical care from ahealthcare professional. Occasionally, an object will enter the lung insteadof being expelled. This can cause coughing, wheezing, or aspiration pneumonia.
