Choking occurs when a foreign object obstructs the airway, preventing airflow to the lungs. Immediate intervention is required to prevent hypoxia and potential cardiac arrest. The standard emergency protocol for a conscious choking person—often referred to as the Heimlich maneuver or abdominal thrusts—involves applying rapid, forceful pressure to the upper abdomen to dislodge the obstruction, according to the American Red Cross.
Recognizing the Signs of Airway Obstruction
A person experiencing a complete airway obstruction typically cannot speak, cough, or breathe. You may observe them clutching their throat, a gesture universally recognized as the universal sign of choking. Other indicators include high-pitched wheezing, difficulty breathing, or skin, lips, or fingernails turning blue or gray due to a lack of oxygen.
If the person can cough forcefully or speak, their airway is only partially blocked. In these instances, the Mayo Clinic advises against interfering, as a strong cough is the most effective way to clear the obstruction. Encourage them to keep coughing until the object is expelled.
Performing Abdominal Thrusts on Adults and Children
When a person cannot breathe or speak, you must act quickly. To perform abdominal thrusts:
- Stand behind the person: Wrap your arms around their waist.
- Position your hands: Make a fist with one hand. Place the thumb side of your fist slightly above the person’s navel, but well below the breastbone.
- Grasp your fist: Cover your fist with your other hand.
- Apply pressure: Perform quick, upward thrusts into the abdomen, as if trying to lift the person up.
Continue these thrusts until the object is forced out or the person becomes unconscious. If they lose consciousness, lower them to the ground and begin CPR, checking the mouth for the object before each set of rescue breaths, per National Safety Council guidelines.
Special Considerations for Infants and Pregnant Individuals
The protocol changes for specific populations to avoid injury:
- Infants (under 1 year): Do not perform abdominal thrusts. Instead, place the infant face-down on your forearm, supporting their head and jaw. Deliver five firm back blows between the shoulder blades with the heel of your hand. If the object remains, turn the infant face-up and perform five chest thrusts using two fingers in the center of the chest.
- Pregnant or Obese Individuals: If you cannot wrap your arms around the person’s waist, perform chest thrusts instead. Place your hands at the base of the breastbone and apply firm, inward thrusts to the chest.
When to Seek Emergency Medical Care
Even if you successfully dislodge the object, internal injury can occur. If the person experienced a prolonged period of oxygen deprivation, or if you suspect you may have caused injury during the rescue maneuver, seek professional medical evaluation. If the obstruction is not cleared after your initial attempts, call emergency services immediately. Keeping a calm demeanor is essential for effective execution of these life-saving skills.
