Management of Suspected Choking
The first step in managing a case of suspected choking is to deliver five sharp back blows to the middle of the back while holding the victim in a prone position with the head lower than the chest. 1
Initial Assessment and Recognition
- Quickly recognize signs of severe airway obstruction: silent cough, cyanosis, inability to speak or breathe, and the universal choking sign (victim clutching their neck) 1
- Ask "Are you choking?" - if the victim nods without speaking, this confirms severe airway obstruction 1
- Never perform blind finger sweeps of the pharynx as these can impact a foreign body further into the larynx 1
Management Algorithm for Adults
Step 1: Back Blows
- Deliver five sharp blows to the middle of the back 1
- Position the victim in a prone position with head lower than chest 1
- For a standing victim, stand slightly behind them and support their chest with one hand 1
Step 2: Abdominal Thrusts (Heimlich Maneuver)
- If back blows are unsuccessful, proceed to abdominal thrusts 1
- For conscious adults, use the upright position (Heimlich maneuver) 1
- Place the heel of one hand in the middle of the upper abdomen, directed upwards toward the diaphragm 1
- Deliver five sharp upward thrusts 1
- Be aware that incorrect technique can cause complications such as gastric rupture 2
Step 3: Check Mouth
- After five back blows and five abdominal thrusts, check the mouth 1
- Remove any visible foreign bodies 1
Step 4: Repeat Cycle
- Continue alternating between back blows and abdominal thrusts until the airway is cleared 1
Management Algorithm for Infants (<1 year)
- Hold the infant along the forearm with head lower than chest 1
- Deliver five back blows 1
- Turn infant to supine position with head lower than chest 1
- Perform five chest thrusts (NOT abdominal thrusts) 1
- Chest thrusts should be sharper and at a more vigorous rate than CPR compressions (about 20 per minute) 1
- Abdominal thrusts are NOT recommended in infants due to risk of rupturing abdominal viscera 1
For Unconscious Victims
- If the victim becomes unconscious, place them on their back 1
- Open the airway using head tilt-chin lift maneuver 1
- Look for visible obstructions in the mouth and remove if seen 1
- Attempt rescue breathing - if unsuccessful, reposition the head and try again 1
- If breathing cannot be established, begin CPR with chest compressions 1
Special Considerations
- Risk factors for choking include neurological disorders, dysphagia, and dental issues 3, 4
- Elderly patients and those on CNS-acting medications (antipsychotics, antiepileptics) are at higher risk of choking due to impaired swallowing 4
- In care home settings, airway clearance devices may be considered as an adjunct to standard procedures when conventional methods are ineffective 5
Common Pitfalls to Avoid
- Delaying intervention - choking is a time-critical emergency requiring immediate action 6
- Performing blind finger sweeps which may push the object deeper 1
- Using abdominal thrusts in infants 1
- Applying excessive force during abdominal thrusts, which can cause internal injuries 2
- Failing to activate emergency medical services if initial attempts to clear the obstruction are unsuccessful 1
