You treat choking in an unresponsive infant by giving:

• A. CPR
• B. Back blows
• C. Heimlich maneuver
• D. Rescue breaths only

Answer: (A)

When an infant who is choking becomes unresponsive, the priority is to provide circulation and ventilation rather than performing choking maneuvers. This is why CPR is the right approach: chest compressions help circulate oxygen-rich blood to the brain and other vital organs, and rescue breaths ventilate the lungs so oxygen can reach the blood.

Back blows or chest thrusts are techniques used for a responsive infant who is actively choking, because the infant can cooperate and you’re aiming to relieve the obstruction. The Heimlich maneuver is intended for conscious individuals and is not used in infants. Rescue breaths alone don’t sustain circulation the way compressions do, so in an unresponsive infant you need the CPR sequence: chest compressions followed by rescue breaths, repeated in cycles.

In practical terms, use two fingers to compress the chest about 1.5 inches (4 cm) at a rate of 100–120 compressions per minute, delivering 30 compressions, then give 2 breaths, and repeat. If the airway shows the object and you can remove it safely, do so, but do not delay CPR to try to extract it. Call for emergency help as soon as possible if you haven’t already.
