Cardiac resuscitation is a medical procedure used to restore normal heart function in individuals experiencing cardiac arrest. This emergency technique involves performing CPR (cardiopulmonary resuscitation) to maintain blood flow and oxygen delivery to vital organs until professional help arrives. In addition to CPR, the use of an AED (automated external defibrillator) may be necessary. An AED can analyze the heart's rhythm and deliver an electric shock if needed, helping to reset the heart's electrical activity. Prompt action during cardiac arrest can significantly increase the chances of survival and recovery.
