Research has shown that chest resistance can vary significantly from patient to patient.
Patients with low impedance are generally easier to defibrillate because the flow of
current meets little resistance. Those with higher impedance may be more difficult to
defibrillate. According to the International Guidelines 2000 by the American Heart
Association (AHA) in collaboration with the International Liaison Committee On
Resuscitation (ILCOR), average adult impedance is 70-80 ohms. Defibrillation energy
should be designed to optimize the delivery of current over a wide range of patient
impedances. Too much current to the myocardial cells can cause damage to the cells
and result in an unsuccessful defibrillation. Too little current to the myocardial tissue
cells will not depolarize the cells and result in an unsuccessful defibrillation.
The waveform biphasic technology:
1) Makes it easy to compensate the shock waveform to match the patient impedance,
2) Is more efficient than monophasic technology,
3) Delivers enough energy for restoring heart rhythm.
