Cardiopulmonary Resuscitation (CPR) Practice

The primary purpose of using defibrillation during CPR is to restore normal heart rhythm. In cases of life-threatening arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia, the heart is unable to pump blood effectively, leading to a state where the individual is not receiving adequate blood flow to vital organs, including the brain. Defibrillation delivers a controlled electrical shock to the heart, aiming to reset its electrical activity. This shock can interrupt the disorganized electrical activity and allow the heart to re-establish a coordinated rhythm, which is critical in regaining effective circulation and improving the chance of survival. Restoring a normal heart rhythm is essential for re-establishing effective blood flow and oxygen delivery throughout the body.
