What is the proper technique for performing chest compressions in adults during CPR?

The technique for performing chest compressions in adults during CPR involves placing two hands on the lower half of the sternum. This method is deemed correct because using two hands allows for greater force and depth in the compressions, which is essential for effectively circulating blood during cardiac arrest. The depth of compressions should be at least 2 inches, and using both hands helps achieve this requirement while also maintaining a proper rate of 100 to 120 compressions per minute.

Positioning the hands this way ensures that the compressions can be delivered with optimal force and reduces the risk of injury to the ribs. This technique also allows the rescuer to maintain stability and control throughout the process, which is vital for maximizing the effectiveness of CPR. In adult patients, where the chest is larger and more rigid, the two-hand technique is particularly important for ensuring adequate blood flow to the heart and brain during the critical moments of resuscitation.
