when giving back blows to an infant, in what position should you hold them?

When giving back blows to an infant, you should hold the infant face-down along your forearm, with their head lower than their body. Support the infant's head and neck with your hand, cradling the back of the head and keeping the head lower than the chest to use gravity to help dislodge the blockage. The infant's body is generally supported on your forearm and thigh or lap. Give firm back blows with the heel of your hand between the infant's shoulder blades, avoiding the head and neck area. This position ensures safety and effectiveness in attempting to clear an airway obstruction by using gravity and controlled force. After 5 back blows, if the object is not dislodged, the infant is turned face-up with their head still lower than the chest to perform chest thrusts if necessary. This method is recommended and demonstrated in various first aid guidelines and instructional videos.
