BLS ASSESSMENT (C.A.B.(D))
Determine unresponsiveness and briefly check for effective breathing. If unresponsive, call a “code” or 911.
C(1) = Circulation: evaluate for signs of a pulse (10 seconds max). If pulse is absent:
begin and maintain compressions, 30 rapid, deep compressions at 100-120 per min
A(2) = Airway: open it with a head tilt / chin lift or jaw thrust if neck trauma is suspected
B(3) = Breathing: administer 2 breaths after the 30 compressions. If an advanced airway device is
placed, ventilate once each 6 seconds while compressions continue.
D(4) = Defibrillation: bring and attach a monitor/defibrillator or an AED to the patient
shock as soon as appropriate
