What is Defibrillation useful for?
Treatment of choice to terminate VF and pulseless VT.
What is critical to a successful patient outcome?
Rapid defibrillation (within two minutes).
What happens during Defibrillation?
DC electric shock through the heart that is sufficient to depolarize the cells of the
myocardium, subsequent repolarization of myocardial cells will allow SA node to
resume the role of the pacemaker.
What is monophasic defibfrillation?
Deliver energy in one waveform.
What is biphasic defibrillation?
Delivers successful shocks at lower energies with fewer postshock ECG abnormalities
than monophasic defibrillators.
What is defibrillation measured in?
Joules or watts.
What are biphasic defibrillators set at?
120 - 220 joules.
What are monophasic defibrillators set at?
360 joules.
After the initial shock in defibrillation, what must be started immediately?
CPR with chest compressions.
What are the guidelines for defibrillation?
CPR should progress until defibrillator is available, turn defibrillator on, select proper
energy level, check that the synchronizer is turned off, apply conductive materials, one
to the right of the sternum just below the clavicle and the other to the left of the apex.
