What is the appropriate chest compression technique for adults?

The appropriate chest compression technique for adults involves using two hands, specifically the heel of one hand placed on the center of the chest, with the other hand placed on top and interlaced fingers. This method ensures that adequate force is applied to the chest, allowing for effective compression and venous return to the heart. The use of two hands allows the rescuer to generate enough pressure, which is critical for promoting blood circulation during cardiac arrest. Proper hand positioning and technique are vital for maximizing the effectiveness of the compressions, which should be delivered at a rate of about 100 to 120 compressions per minute and at a depth of at least 2 inches. This method is widely endorsed in basic life support training and guidelines to ensure optimal outcomes during resuscitation efforts.
