Defibrillator Pulse Playback
The Analyzer allows the user to play the defibrillator pulse waveform for the
purpose of analysis. Playback is accomplished using a strip recorder or
defibrillator monitor through the ECG jacks or scope output. The waveform
can also be reviewed on an oscilloscope through the high-level ECG outputs.
To play back the defibrillator pulse:
1. Power up the defibrillator and the Analyzer.
2. From Main Menu 1, press the ENRG softkey to access the Energy
menu, and press the WAV> softkey to access the WAV submenu.
3. Connect the ECG patient leads to the Analyzer as shown in Figure 2-7.
4. After the defibrillator discharges, press the PLAY softkey. The last
defibrillator pulse is replayed.
