Why is it important to keep the heel of the hand lightly in contact with the chest during chest compressions?

1. To prevent injury

2. To ensure correct hand position

3. To monitor patient response

4. To increase speed of compressions

The correct answer is: To ensure correct hand position

Keeping the heel of the hand lightly in contact with the chest during chest compressions is important to ensure correct hand position. Maintaining proper hand placement is crucial because it allows for effective compressions that are both deep and at the appropriate rate. When the hands are positioned correctly on the chest, this maximizes the efficiency of blood flow during each compression. It also helps to maintain the same location on the chest, which is vital for consistent compressions throughout the resuscitation process. Proper hand positioning reduces the risk of compressing the stomach or ribs accidentally, which can compromise the effectiveness of CPR and potentially cause injury to the patient. Additionally, being aware of the hand position ensures that the compressions are delivered in the center of the chest, directly over the sternum, where the heart is located, maximizing the chances of adequate circulation during cardiac arrest.
