Final answer:
Back blows should be aimed between the shoulder blades using the heel of your hand while the person is leaning forward. For infants, the baby is turned face down for back slaps. If the object remains lodged after back blows and the Heimlich maneuver, seek emergency medical assistance.
Step-by-step explanation:
When giving back blows to a person who is choking, it is critical to target the correct area on the back to help dislodge the object obstructing the airway. In adults and children over one-year-old, back blows should be administered between the shoulder blades with the heel of your hand. Make sure the individual is leaning forward before you give five sharp and distinct blows in an attempt to clear the obstruction. If the person is still choking, alternate between back blows and abdominal thrusts, commonly known as the Heimlich maneuver. For an infant under one-year-old, turn the baby face down on your forearm, supported by your thigh, and give firm back slaps between the shoulder blades with the heel of your hand.
Remember, if someone is choking, encourage them to cough and only proceed with back blows if the coughing is not effective. If the choking persists after attempting back blows and the Heimlich maneuver, it is crucial to call for emergency medical care immediately.
