Ask clearly: 'Are you choking?' If they can cough forcefully, speak, or make sound — let them keep coughing. A strong cough is the body's most powerful way to clear an airway.
Stand to their side and slightly behind. Lean them forward. Use the heel of your hand to deliver 5 firm blows between the shoulder blades.
Stand behind them. Make a fist just above the navel. Grab fist with your other hand. Give 5 sharp inward-and-upward thrusts.
Keep alternating: 5 back blows then 5 thrusts. Check the mouth between cycles. Remove a visible object only if you can clearly see it — no blind finger sweeps.
Lower them carefully to the floor. Call 911 immediately. Begin CPR. Before every rescue breath, look into the mouth and remove any visible object.
Guidance only — in any emergency, call 911.
