9 Technical Description
The “Technical Description” section describes the technical data of the unit valid at the time
of printing
Operating mode
•
Responder 1000
, non-synchronized defibrillation
•
Responder 1100
, non-synchronized and synchronized defibrillation
Energy selection
•
Selectable energy levels, energy to be delivered into a 50-ohm external resistance (max.
energy of 50 joules for internal defibrillation by

joules
•
possible deviation from selected energy less than deviations permitted by IEC regulations
Energy storage
By means of capacitor, capacitor is charged from the power line or from battery.
Typical capacitor charge time to energy level of 360 joules:
•
at line voltage or from full charged battery: 11 s
at 90% of line voltage or from partially discharged battery: 12 s (15 s max.)
measured at least 5 minutes after 15 shocks of 360 joules each
•
internal safety discharge (see Safety discharge)
•
stored energy level indicated by LED's
•
"charge done" indicated by buzzer
Defibrillation shock
Capacitor discharge via induction coil (damped serial resonant circuit), pulse shape resembling
sinusoidal halfwave with decay period
•
pulse duration for an external resistance of 50 ohms approximately 4.2 ms, measured from
beginning of the pulse to the intersection of the zero line and the inflection point of the trailing
pulse edge
•
in synchronized mode the defibrillation shock is released within 25 ms of the R-wave trigger
