Primary Care Baseline - V Fib/V Tach Algorithm

V Fib/V Tach Algorithm

defibrillate x3 (200, 200-300, 36 J)

electromechanical dissociation (EMD)? YES -> EMD algorithm

return to spontaneous circulation? YES -> vital signs, airway, breathing, O2 NO -> continue CPR, intubate, IV access, epinephrine 1mg IV q3-5 min, defibrillate 360 J 1 min after each dose

consider sodium bicarbonate

drug-shock, drug-shock from this point on

continued v fib/v tach? YES -> lidocaine 1.5 mg/kg IV q3-5 min up to 3 mg/kg

continued v fib/v tach? YES -> bretylium 5 mg/kg IV, repeat 10 mg/kg after 5 min

torsade de pointes or hypomagnesemia? YES -> magnesium sulfate 1-2 g IV

continued v fib/v tach? YES -> procainamide 30 mg/min IV up to 17mg/kg
