Defibrillator Monophasic waveformvary in the speed with which the waveform returns to the zero voltage point- either gradually (damped sinusoidal) or instantaneously (truncated exponential) Biphasic waveformfirst flows in a positive direction for a specified duration, in the second phase the device reverses the direction of current so that it flows in a negative direction adjusts the amount and duration of current delivered based on impedance measurements performed twice during every shock provides equivalent defibrillation success at lower energy levels than those of monophasic shocks and eliminates the need to increase the energy for persistent VF

Biphasic waveformMultipulse Biowave

The Schiller Biphasic Defibrillation Waveform (Multipulse Biowave)DefibrillatorTo be effective the defibrillation shock has to provide an adequate level of current 22 Amperein a very precise period of time 4 ms and with the lowest possible energy Energy (Joules) is harmful and causes burns

t[s]00.5102004006008001000No currentThere is NO CURRENT and so NO ENERGY half of the time !CurrentThe defibrillation shock is pulsed

High current is so obtained but with only half energy

The duration of the 2 pulses is always fixed to 4 ms, corresponding to the excitation time of the cardiac cells

Amplitude of the negative pulse is adapted in order to eliminate charges built up by the first phase and will so prevent from a possible refibrillation

t[ms]Vd Vm Negative pulse amplitude is well adjustedElectrical charges built up by the positive shock are totally eliminatedDefibrillator: Options12 ECG leads on the screen (*with interpretation)SpO2NIBPRecorderPacemaker
