What is the Heimlich maneuver also known as?

The Heimlich maneuver is indeed known as abdominal thrusts. This technique is specifically designed to expel an object that is obstructing a person's airway, particularly in cases of choking. By using a series of quick inward and upward thrusts to the abdomen, the air pressure created within the chest can help dislodge the foreign object.

The term "abdominal thrusts" directly describes the physical action performed during the maneuver, emphasizing the focus on the abdominal area where the thrusts are applied. This terminology is widely recognized in first aid training and emergency response guidelines, making it clear and distinct in its purpose and action.

Other choices like self-defense, compression technique, and rescue breathing refer to entirely different concepts in emergency response and first aid. Self-defense pertains to protecting oneself from an aggressor, compression technique often relates to chest compressions in CPR, while rescue breathing is about providing breaths to someone who is not breathing.
