What is the first step in performing the Heimlich maneuver?

The first step in performing the Heimlich maneuver involves positioning yourself behind the person who is choking. This is crucial because it allows you to effectively apply the necessary abdominal thrusts to relieve the obstruction in the airway. By standing behind the individual, you can gain better access to their abdomen and maintain control over the situation.

When properly positioned, the rescuer can wrap their arms around the person's waist, which is essential for delivering the thrusts with sufficient force and precision. This positioning is fundamental to the technique, as it provides the physical support needed for both the rescuer and the person who is choking.

The other steps mentioned, while important in the overall response to someone choking, come after this initial positioning. For example, calling for help is a critical action but should follow after ensuring readiness to assist. Encouraging the individual to cough is also important, particularly if they are still able to do so, but it is a response that occurs before you position yourself for the maneuver. Similarly, applying back blows can be effective, but it is not part of the Heimlich maneuver itself and typically precedes the abdominal thrusts if the initial positioning has not yet occurred. Thus, for effective execution of this lifesaving procedure, positioning yourself behind the person is
