Answer :
The Heimlich maneuver helps unblock a person's airway by pushing the diaphragm, causing a person's ribs to contract, which pushes the blockage out. When someone is choking, the blockage is usually food or another object lodged in the airway. By applying pressure on the diaphragm with upward thrusts, it creates a force that compresses the lungs, increasing the pressure in the chest cavity. This increased pressure helps dislodge the blockage and expel it from the airway.
It is crucial to perform the Heimlich maneuver correctly to avoid causing harm. Incorrectly performed, it could lead to injuries such as broken ribs. Proper training in first aid is essential to ensure that the maneuver is executed effectively in emergency situations. Remember, if someone is choking, it's crucial to act quickly and seek help if needed to assist the person effectively.
