When dealing with an obstructed airway in a responsive infant, the correct method for clearing the obstruction is through a combination of back blows and chest thrusts. This approach is effective because it utilizes the infant’s own body mechanics to expel the object causing the blockage. Back blows are delivered between the infant's shoulder blades with the heel of the hand, and these forceful actions can help dislodge the obstruction. If back blows are not effective, chest thrusts are then applied, which involve placing two or three fingers just below the nipple line and compressing the sternum, similar to a mini-chest compression.

This method is specifically designed for infants who are alert and responsive. It is essential to avoid methods such as heavy shaking, which may cause injury, or solely relying on chest compressions, as they do not target the blockage as effectively. Non-responsive measures, like singing to the infant, do not address the immediate need to clear the airway and could prove to be ineffective in an emergency situation. Thus, utilizing back blows and chest thrusts becomes a clear and proven method in first aid protocols for responding to choking infants.
