Here are the essential concepts you must grasp in order to answer the question correctly.
Heimlich Maneuver
The Heimlich maneuver is a first aid technique used to treat choking. It involves placing your arms around the waist of the choking person and delivering quick, upward thrusts to the abdomen. This action increases pressure in the abdominal cavity, which can help dislodge the object blocking the airway.
Airway Obstruction
Airway obstruction occurs when an object, such as food, blocks the flow of air to the lungs. This can lead to choking, which prevents the person from breathing properly. Understanding how the obstruction occurs is crucial for applying the Heimlich maneuver effectively to restore airflow.
Increased Abdominal Pressure
When performing the Heimlich maneuver, the upward thrusts create a rapid increase in pressure within the abdominal cavity. This pressure forces air from the lungs upward, which can expel the obstructing object from the airway. The mechanics of this pressure change are essential for understanding how the maneuver works.
