Which hand position saves tiny lives? study pits four infant CPR techniques Head-to-Head

This study compares four different chest compression techniques for infant CPR using a manikin. Emergency medicine residents will perform two minutes of CPR with each technique—two-finger, three-finger, heel-of-one-hand, and two-thumb—in a random order. Researchers measure compression depth, rate, release speed, and how many compressions hit the target range, along with rescuer fatigue and difficulty. The goal is to identify which technique is most effective and least tiring for a single rescuer.
