What to do when a person is choking on water?

If a person is choking on water, encourage them to cough forcefully to expel the liquid. If they cannot cough, speak, or breathe, perform the Heimlich maneuver by standing behind them, placing your arms around their waist, and delivering quick inward and upward thrusts. If they remain unresponsive, call emergency services immediately and begin CPR if necessary. Always ensure the person is seated upright while drinking to minimize choking risks.
