What is the Heimlich maneuver used for?

The Heimlich maneuver is specifically designed to help dislodge food or other objects that are obstructing a person's airway, which can lead to choking. When someone is choking, they may show signs such as difficulty breathing, inability to speak, or a distressed look. The Heimlich maneuver involves applying pressure to the abdomen, just above the navel, to create a force that can expel whatever is causing the blockage in the airway. This technique is crucial as choking can quickly become life-threatening.

The other options do not correctly describe the purpose of the Heimlich maneuver. Reviving someone who has fainted typically requires different techniques, such as ensuring the person is lying down and elevating their legs. Treating a heart attack involves recognizing symptoms like chest pain and may require CPR or the use of an AED, but it is unrelated to the Heimlich maneuver. Similarly, chest compressions are part of CPR used in cases of cardiac arrest, not for addressing choking situations.
