always provides “tocks” and ventilation prompts at the set ratio for both AED mode and Manual
mode. In this situation, the CPR Metronome menu does not appear when CPR is pressed during
use—pressing the CPR button only activates and deactivates the metronome at the fixed C:V
ratio.
Synchronized Cardioversion Procedure
The LIFEPAK 15 monitor/defibrillator can be set up to remain in Sync mode or to return to
Asynchronous mode after a shock is delivered. The factory default setting is to return to
Asynchronous mode after a shock. It is important that you know how your defibrillator is set up. For
information about changing the setup option, see the LIFEPAK 15 Monitor/Defibrillator Setup
Options provided with your device.
To perform synchronized cardioversion:
1. Press ON .
2. Attach patient ECG cable and ECG electrodes as previously described (see "Monitoring the ECG"
on page 4-3). ECG electrodes and cable must be used to monitor the ECG when standard
paddles are used for cardioversion.
3. Select Lead II or lead with greatest QRS complex amplitude (positive or negative).
Note: To monitor the ECG using therapy electrodes, place the electrodes in anterior-lateral
position and select PADDLES lead.
4. Press SYNC . The SYNC MODE message appears in the message area when Sync is active.
Note: Press SYNC again to deactivate Sync mode.
5. Observe the ECG rhythm. Confirm that a triangle sense marker ( ) appears near the middle of
each QRS complex. If the sense markers do not appear or are displayed in the wrong locations
(for example, on the T-wave), adjust ECG SIZE or select another lead. (It is normal for the sense
marker location to vary slightly on each QRS complex.)
6. Connect the therapy electrodes to the therapy cable and confirm cable connection to the
defibrillator.
WARNING
POSSIBLE LETHAL ARRHYTHMIA
Ventricular fibrillation may be induced with improper synchronization. DO NOT use
the ECG from another monitor (slaving) to synchronize the monitor/defibrillator’s
discharge. Always monitor the patient’s ECG directly through the defibrillator’s ECG
cable or therapy cable. Confirm proper placement of the sense markers on the ECG.
