What position should the victim's body be in for effective CPR?

For effective CPR, the victim's body should be positioned flat on their back. This position is essential because it allows for the most effective compression of the chest. When a person is lying on their back, the rescuer can apply downward force directly over the sternum, which is critical for creating enough pressure to circulate blood during cardiac arrest. This position also opens the airway, making it easier for rescue breaths and ensuring that oxygen can reach the lungs. The flat position is necessary to facilitate both the compressions and breaths efficiently, maximizing the chances of reviving the victim.
