During CPR, how should your hands be positioned on the patient's chest?

The proper hand positioning during CPR is crucial for providing effective chest compressions, which aim to circulate blood to vital organs when the heart is unable to do so. The correct method involves placing two hands, one on top of the other, with fingers interlaced at the center of the patient's chest. This configuration allows the provider to deliver strong, consistent compressions, utilizing the weight of the body to maximize force and decrease fatigue over time.

Interlacing the fingers prevents the rescuer's hands from slipping, ensuring that compressions are delivered efficiently and at the correct depth. It also allows for better control and stability compared to other hand positions that may not provide adequate force or could lead to ineffective compressions.

The other methods listed are either ineffective or not recommended. For instance, placing one hand above the other would not apply enough force directly to the sternum, while having both hands flat on the chest could hinder the depth needed for effective compressions. Lastly, one hand on the forehead and one on the chest is not suitable, as it does not provide the necessary pressure to circulate blood effectively. Emphasizing proper hand placement and technique is essential for successful CPR outcomes.
