    • Call for Help and Activate Emergency Response:
      • Immediately shout for help to alert anyone nearby.
      • Call emergency services (911 or the local emergency number) yourself if you are alone. If others are present, instruct someone specifically to call emergency services and bring an AED if one is available.
    • Check for Breathing and Pulse:
      • Quickly assess the person for normal breathing and check for a pulse for no more than 10 seconds.
      • Agonal gasps are not normal breathing; they are a sign of cardiac arrest.
    • Begin CPR:
      • Chest Compressions:
        • Place the heel of one hand on the center of the chest, with the other hand on top, interlocking your fingers.
        • Perform chest compressions at a rate of 100 to 120 compressions per minute.
        • Compress the chest at least 2 inches (5 cm) deep, allowing full recoil between compressions.
      • Rescue Breaths:
        • If trained and able, after 30 compressions, give 2 rescue breaths. Tilt the person’s head back, lift the chin, pinch the nose shut, and give breaths lasting about 1 second each, watching for the chest to rise.
    • Use an AED as Soon as It Arrives:
      • Once the AED arrives, turn it on and follow the voice prompts.
      • Attach the AED pads to the person’s bare chest as indicated.
      • Ensure no one is touching the person while the AED analyzes the heart rhythm.
      • Deliver a shock if the AED advises it, ensuring everyone is clear of the person.
      • Immediately resume CPR starting with chest compressions after the shock or if no shock is advised.
    • Continue CPR:
      • Continue performing CPR with cycles of 30 compressions and 2 breaths until emergency medical personnel arrive, the person shows signs of life (such as normal breathing, movement), or you are too exhausted to continue.
