The DEFIBRILLATOR TESTS MENU contains a series of interactive waveforms in
which the patient simulator outputs a fibrillation waveform that can be "defibrillated"
either by a menu selection ("defib") or by inputting a pulse signal through the "SYNC/A-
PACE" jack.
Obtain this pulse signal by discharging a defibrillator into a Fluke Biomedicals
Defibrillator Analyzer that is connected through the Real Time Output to the
medSim 300B through the "SYNC/A PACE" jack.
In the emergency simulations ("EMI" and "EM2"), the pulse signal can be inserted at any
time during ventricular fibrillation for successful defibrillation.
In the cardioversion ("CARD") mode, the pulse must be synchronized with the R-wave
and must come within 100 ms (before or after) the peak of the R-wave. If the pulse signal
is inserted within this time window, the simulator is defibrillated successfully. If the
pulse signal is inserted outside this time window, the ECG waveform changes to
ventricular fibrillation, and the simulator can then be defibrillated back to a normal
waveform.
The successful defibrillation waveform for all series is a negative pulse that takes
3 seconds to recover to a flat line, then 3 nodal beats at 30 BPM, then 6 nodal beats at
60 BPM, and ends with continuous normal beats at 80 BPM.
The waveform for an unsuccessful defibrillation, when in cardioversion, is the same
negative pulse and 3 seconds of recovery followed by ventricular fibrillation.
Function Select - Defibrillator Tests -Emergency 1 Menu
"Emergency 1" generates a series of 10 normal beats, a PVC (R on T), 6 normal beats,
another PVC (R on T), and then a continuous fine ventricular fibrillation.
