While performing chest compressions, you should?

When performing chest compressions, positioning your shoulders directly over your hands is essential for effective compressions. This alignment maximizes the force exerted through the compressions, ensuring that each push is effective in circulating blood throughout the body. Proper body mechanics, including shoulder alignment, helps the rescuer maintain endurance during prolonged resuscitation efforts and enhances the efficiency of each compression.

Additionally, proper technique requires that the rescuer keep their arms straight, which allows gravity to assist with the downward force. While the compressions should be performed at a specific rate and depth, the focus on shoulder positioning is crucial for maximizing effectiveness and minimizing the risk of fatigue.
