What is a common intervention for a choking person who cannot speak or breathe?

When a person is choking and is unable to speak or breathe, performing the Heimlich maneuver is the appropriate intervention. This technique is designed to create a sudden increase in abdominal pressure, which can help expel the lodged object from the airway. It is a lifesaving procedure that can dislodge materials blocking the airway, allowing the person to breathe and speak again.

Encouraging the individual to cough is generally advised if they can still make sounds and are capable of managing their airway. However, in a situation where they cannot speak or breathe, this option is not suitable. Providing water to sip is also contraindicated, as drinking can worsen the choking by further obstructing the airway. Lastly, checking for a pulse does not directly address the immediate need to clear the airway, as the priority is to restore breathing. Thus, the Heimlich maneuver becomes the necessary action to assist someone who is choking and unable to breathe or speak.
