Choking: The Response for Adult, Child, and Infant

A choking person cannot ask for help — the object blocking the airway prevents speech. The signs are specific and the response window is under 4 minutes before brain damage from lack of oxygen. Every adult in a household should know the technique for their age group of family members. The specific difference between knowing and not knowing is often life.

Signs of choking

• Inability to speak or cough forcefully.
• High-pitched wheezing or squeaking.
• Weak, ineffective cough.
• Hands clutching throat (universal signal).
• Face turning red then blue.
• Loss of consciousness if prolonged.

If they can cough forcefully

• Do NOT intervene.
• Encourage them to keep coughing.
• Stay with them; be ready to act if they can't.
• A person who can cough or speak has partial airway obstruction that they may clear themselves.

Adult / older child — Heimlich manoeuvre

• Stand behind the person.
• Place one foot between their feet for balance.
• Wrap your arms around their waist.
• Make a fist with one hand, thumb side against abdomen, just above navel.
• Grasp fist with other hand.
• Give quick, forceful inward and upward thrusts.
• Repeat until object is expelled or person becomes unresponsive.
• If unresponsive: begin CPR (chest compressions can dislodge object).

If the person is pregnant or too obese for abdominal thrusts

• Use chest thrusts instead.
• Fist placed on breastbone (sternum).
• Straight backward thrusts.

Child 1-8 years — modified Heimlich

• Kneel or stand behind them for their height.
• Less force than adult — smaller person.
• Same technique.
• Alternate with 5 back blows if not effective (some guidelines).

Infant under 1 year — DIFFERENT technique

• Do NOT do abdominal thrusts on an infant (organ damage risk).
• Support infant face-down along your forearm, head lower than body, jaw supported.
• Give 5 firm back blows between shoulder blades with heel of hand.
• If not cleared, turn infant face-up on your forearm.
• Give 5 chest thrusts with two fingers on breastbone just below nipple line.
• Alternate back blows and chest thrusts until object expelled or infant becomes unresponsive.
• If unresponsive: begin infant CPR and call ambulance.

Self-choking — if alone

• If nobody is around, try self-Heimlich.
• Make a fist above your navel.
• Grip with other hand.
• Thrust upward into abdomen.
• Or use back of a chair — lean over it firmly, driving abdomen against back of chair.
• Or call ambulance and follow their instructions.

After the object is expelled

• Person should still see a doctor.
• Aggressive thrusts can cause internal injuries.
• Aspiration of small fragments possible.
• Rib fracture possible especially in older people.
• Any persistent cough, breathing difficulty, or chest pain needs assessment.

Prevention

• Cut food into small pieces, especially for elderly and children.
• Chew thoroughly, eat slowly.
• Don't eat while walking, running, playing.
• Common choking foods for children: grapes (halve), peanuts, hot dogs, hard candy, raw carrots.
• Keep small objects (coins, buttons, magnets) away from young children.
• Elderly with swallowing difficulty (dysphagia): specialist evaluation, texture modification.
• Denture-wearing elderly at higher risk — annual dental review.

The specific dysphagia consideration

Post-stroke patients, elderly with cognitive impairment, and some Parkinson's patients have specific swallowing problems that increase choking risk. Speech-language pathologists assess and recommend food texture modification. This is often overlooked in Indian home care and is a specific cause of aspiration pneumonia and choking events.

Every adult in a household with elderly members or young children should have watched a Heimlich manoeuvre video and practised the motion. The specific 30 seconds it takes to learn saves lives when needed.
