NOTE
z The conductive ointment coatings should be isolated, and the chest
electrodes should have no contact with each other to avoid short-circuit.
z Do not use the physiological saline, which erodes the electrodes,
instead of the electrode gel.
z Using 3M electrodes is recommended during defibrillation.
