Educational Pearls:

  • Defibrillation is used to depolarize the heart and reset the electrical activity. How can the success of defibrillation be maximized for a patient with persistent Vfib and has been shocked several times previously by EMS.  
  • Success is dependent on the contact of the pads with the chest. Drying off a patient, removing hair and increasing pressure can all improve success, but so can dual sequential defibrillation.
  • Dual sequential defibrillation is the use of 2 simultaneous defibrillators to increases the amount of electricity reaching the heart.
  • One set of pads from each defibrillator are placed in the AP lateral position and the other set of pads are placed in the AP posterior position.
  • This is generally considered a safe technique to increase the electricity to the heart and the chances of success of defibrillation.
