What is the purpose of the head-tilt/chin-lift technique in infant CPR?

The head-tilt/chin-lift technique is specifically designed to open the airway in an infant during CPR. This maneuver is crucial because it helps to reposition the airway structures and relieve any obstruction that may prevent air from flowing into the lungs. In infants, the airway can easily become blocked or collapsed due to their anatomical differences, including a larger head relative to body size and softer trachea. By tilting the head back slightly and lifting the chin, this technique aligns the airway, allowing for better ventilation. This step is vital in CPR to ensure that rescue breaths can be delivered effectively, ultimately improving the chances of resuscitation. The emphasis here is on maintaining a clear and open airway, which is fundamental for breathing and circulation during a cardiac emergency.
