How should chest compressions be executed on an adult?

The execution of chest compressions on an adult is critical for effective cardiopulmonary resuscitation (CPR). To perform these compressions correctly, the guidelines emphasize the importance of using the heel of one hand while keeping the arms straight. This technique allows for maximum force to be applied to the center of the chest, which is necessary for generating adequate blood circulation during cardiac arrest.

When the arms are straight, the rescuer can utilize their body weight to aid in the compressions, making them more effective while also reducing strain on the arms. Properly positioning the hands ensures that the compressions are delivered at the appropriate depth and rate, which is vital for successful resuscitation efforts. The recommended depth for adult compressions is at least 2 inches, and the rate should be around 100 to 120 compressions per minute.

This technique contrasts with other methods, such as bending elbows or placing hands in ineffective positions, which may hinder the effectiveness of compressions and reduce the chance of restoring normal heart function. Therefore, knowing the correct way to perform chest compressions is essential for anyone involved in CPR, enabling the rescuer to provide the best possible chance of survival for the victim.
