How do you treat choking in an unresponsive infant?

When treating choking in an unresponsive infant, the American Heart Association (AHA) recommends a series of steps to clear the airway obstruction. The correct procedure involves first delivering back blows followed by chest thrusts.

Back blows: To perform back blows, the rescuer should lay the infant face down along their forearm, supporting the head and neck with the hand. With the infant's head lower than the body, the rescuer delivers up to five back blows between the infant's shoulder blades using the heel of the hand.

Chest thrusts: If back blows fail to clear the obstruction, the rescuer should then perform chest thrusts. For chest thrusts, the infant should be placed face up on a firm surface. The rescuer then delivers up to five chest thrusts to the center of the infant's chest, just below the nipple line. The chest thrusts are performed by using two or three fingers to push down about 1 1/2 inches.

These steps should be repeated until the object is expelled or the infant becomes responsive. It's crucial to seek emergency medical assistance if the obstruction persists.
