 Prior to defibrillation the operator should ensure that the defibrillator and the monitor are compatible.
 Prior to synchronous defibrillation with a defibrillator it is necessary to ensure that the Monitor is used
together with the defibrillator to send a synchronous electric shock within 60ms after detection of the
next R wave, and that the ECG output signal is delayed for no more than 30 ms.
