Cardiopulmonary resuscitation (CPR) for adults combines chest compressions and rescue breaths to maintain blood flow during cardiac arrest until emergency help arrives.

An automated external defibrillator (AED) analyzes heart rhythm and delivers an electric shock to restore a normal heartbeat during sudden cardiac arrest. Early defibrillation dramatically improves survival.

Choking occurs when a foreign object partially or completely blocks the airway. Prompt recognition and abdominal thrusts (Heimlich maneuver) can dislodge the obstruction and restore breathing.
