What action should be taken if an adult cannot breathe or speak due to choking?

When an adult is choking and cannot breathe or speak, the most appropriate and effective action is to perform abdominal thrusts, commonly known as the Heimlich maneuver. This technique creates increased pressure within the abdomen that can help expel the object blocking the airway.

This method is vital because choking can quickly lead to loss of consciousness and a life-threatening situation if the airway is not cleared promptly. The abdominal thrusts exert a forceful upward motion on the diaphragm, which may dislodge the obstruction and restore normal breathing.

While encouraging someone to cough might help if they can still breathe and make sounds, it is not suitable for someone who cannot breathe or speak, as their situation is more severe. Calling for help is important in emergencies, but immediate action is crucial when dealing with choking. Leaving the person alone is dangerous and could lead to fatal outcomes. Thus, performing abdominal thrusts is the best course of action to resolve the choking incident effectively.
