When administering back blows or chest thrusts to an infant, what is the correct position for the infant's head and chest?

When performing back blows or chest thrusts on an infant who is choking, it is crucial that the infant's head is positioned lower than the chest. This positioning helps facilitate the expulsion of any obstruction from the airway through gravity. When the head is lower than the chest, the force of gravity assists in dislodging the blockage when back blows are administered.

This method works effectively as it allows the airway to open and helps the infant’s body naturally respond to the obstruction. Maintaining this head position ensures that the airway is more easily cleared during the emergency intervention. It's important for effective first aid practices to follow these guidelines closely for the safety and health of the infant.
