Discharge Circuit
Figure 11-1. Current discharge curve (360 J)
serial oscillating circuit in series with external resistance (patient):
•
capacitance 34 µF
•
inductance 26 mH
•
equivalent resistance 11 Ohms
Defibrillation Pulse Output
isolated, no conductive connection with enclosure, open-circuit and short-circuit-proof as required by
AAMI DF-2:
•
insulation test voltage 8 kV DC, type CF according to IEC 60601-2-4
Safety Discharge
capacitor discharge via internal load resistance:
•
when the defibrillation shock is not triggered within 30 s of charging
•
when the shock is triggered but the discharge circuit is interrupted, after approx. 0.2 s (e.g. when
the shock is triggered into open air)
•
when the battery is full and the selected energy cannot be reached within 20 seconds
•
in the presence of technical malfunctions
•
when the battery is removed
•
when the device is switched off
•
when the electrode connector is removed
Test Features
•
5 indicators (on battery) indicating the battery charge level
•
defibrillator test by discharging the stored energy into the integrated 50-ohm load resistance (max.
twice within 15 minutes)
•
3-digit display of the delivered energy
•
warning on LCD when discharge circuit is interrupted (e.g. pacer electrode not applied)
