Which method is correct for positioning your hands during chest compressions?

Positioning your hands correctly during chest compressions is crucial for effective cardiopulmonary resuscitation (CPR). The correct method involves placing both hands, with one on top of the other, while interlacing the fingers. This technique allows for stronger and more stable compressions, maximizing the force applied to the chest, which is essential for providing adequate blood circulation during cardiac arrest.

By keeping the hands aligned and centered on the lower half of the sternum, the provider can ensure that the compressions are delivered at the right depth (at least two inches in adults) and at the right rate (100 to 120 compressions per minute). The interlaced fingers also help to avoid slipping during compressions, allowing for better control and efficiency throughout the resuscitation efforts.

Other methods, such as placing one hand on the forehead and another on the lower back, do not provide the necessary force or stability required for effective chest compressions. Similarly, having one hand on the chest and one on the abdomen, or placing both hands on the shoulders, would not provide the appropriate compression needed to maintain blood flow to vital organs. Thus, the interlaced hand position is essential for delivering effective CPR.
