Cardiac arrest
abrupt, unexpected loss of heart function, breathing, and consciousness, often fatal if not treated within minutes
Sudden cardiac arrest
when the heart abruptly stops beating, cutting off blood flow, and is fatal without immediate treatment, usually with a defibrillator and CPR
Heart attack
when the flow of blood to the heart is severely reduced or blocked
(CPR)
a life-saving emergency procedure for people in cardiac arrest, combining 30 chest compressions (2-2.4 inches deep, 100-120/min) with 2 rescue breaths
Compression
the action of compressing or being compressed.
Chest recoil
the full expansion of the chest wall back to its resting position between compressions during CPR, allowing the heart to refill with blood
Rescue breaths
Open the airway using the head-tilt, chin-lift maneuver
Chain of survival
series of critical, sequential actions—recognition/activation, CPR, defibrillation, advanced care, post-cardiac arrest care, and recovery
Early recognition
early detection and intervention
Early defibrillation
the prompt delivery of an electrical shock via an Automated External Defibrillator (AED) to treat cardiac arrest caused by ventricular fibrillation or pulseless ventricular tachycardia
