Which type of injury might require the Heimlich maneuver?

The Heimlich maneuver is specifically designed to address complete airway obstructions caused by choking. When an individual has a complete obstruction, they are unable to breathe, speak, or make any sounds, indicating that their airway is blocked and immediate intervention is necessary to dislodge the object causing the obstruction. The Heimlich maneuver involves a series of abdominal thrusts aimed at creating pressure in the abdomen that can expel the obstructing object from the airway.

While a partial airway obstruction can cause choking, the Heimlich maneuver is not typically indicated in these cases, as the person may still be able to breathe or cough effectively. In situations of a severe allergic reaction, especially where airway swelling may occur, other interventions would be required, such as the use of an epinephrine auto-injector. Likewise, a broken rib would not necessitate the Heimlich maneuver and would require a different treatment approach focused on managing pain and preventing further injury. Therefore, the use of the Heimlich maneuver is specifically reserved for instances of complete airway obstruction due to choking, making it the appropriate choice in this scenario.
