In the event of a suspected foreign-body airway obstruction, what should be done first?

In the scenario of a suspected foreign-body airway obstruction, performing the Heimlich maneuver is the appropriate first action because it is specifically designed to help dislodge an object that is blocking the airway. This technique creates abdominal pressure that expels air from the lungs and can push the object out of the airway.

Immediate action is crucial in airway obstruction situations, as they can lead to rapid respiratory failure and potentially life-threatening conditions. The Heimlich maneuver is a direct and effective response, aimed at restoring normal breathing by removing the obstruction as quickly as possible.

The other options, such as calling emergency services, administering oxygen, or using a bag-valve mask (BVM), are responses that can be part of the overall management once the airway is clear or if the obstruction is not resolved. However, these actions do not address the immediate need to remove the obstruction, and delay could compromise the individual’s ability to breathe. Thus, initiating the Heimlich maneuver is critical in this emergency situation.
