For an infant, the Heimlich maneuver is not performed. Instead, the infant is turned face down, the chest resting on the rescuer's hand, with the head lower than the body. The rescuer then strikes the infant between the shoulder blades 5 times using the heel of the hand (back blows). The strikes should be firm but not hard enough to cause injury. The rescuer then checks the mouth, removing any visible objects. If the airway remains blocked, the rescuer turns the infant face up with the head down, thrusts his second and third fingers inward and upward on the breastbone 5 times (chest thrusts), then checks the mouth again.
