18.18.1 Functional principle
A setpoint controls the delivered current, producing a sawtooth-
shaped pulse.

18-1 Basic shape of the CARDIObiphasic shock pulse
The mean ratio of electric charge delivered between the second
(negative) and the first (positive) phase is 0.38.
For safety reasons, voltages of no higher than 2000 V are used.
The resulting currents as a function of patient impedance are
shown in the following graph by way of example.
