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

is pressed during

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

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

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.
