  • Begin BASIC life support : A B C

    • A = Airway - Assess for airway obstruction, assess for breathing, perform intubation
    • B = Breathing - Ventilate with 100% oxygen, 10-24 breaths/minute
    • C = Circulation - Assess for heart beat and pulses if absent, begin chest compressions, 100-120 compressions/minute

  • Begin ADVANCED life support

    • Obtain Electrocardiogram and Determine Arrest Rhythm
    • IV catheter for Drug Therapy and Fluid administration
