8.5.1 Performing Synchronized Cardioversion
1. Connect the therapy cable and apply the multifunction electrode pads or external paddles to the patient. If ECG set
is used for ECG monitoring, connect the ECG trunk cable and apply the ECG electrodes to the patient, referring to 6
Monitoring ECG .
2. With the Mode Select knob in the Manual Defib position, press the [ Enter Sync ] soft key to activate the
synchronous cardioversion function.
3. Select a lead. The selected lead should have a clear signal and a large QRS complex.
4. Verify that a white R-wave marker appears above each R-wave. If the R-wave markers do not appear or do not
coincide with the R-waves, for example above the T-waves, select another lead.
5. Verify that the equipment enters the Sync mode, as indicated by the SYNC mark shown in the defibrillation
information area.
6. Press the Energy Select button to select a desired energy level.
7. Press the Charge button on the equipment’s front panel or, if using external paddles, the Charge button located on
the handle of Apex paddle.
8. Confirm that a shock is still indicated and that the equipment has charged to the selected energy level. Make sure
no one is touching the patient, bed or any equipment connected to the patient. Call out loudly and clearly, “ Stay
Clear! ”.
9. Press and hold the Shock button on the equipment or, if using external paddles, the Shock buttons on both
paddles. The shock will be delivered when the next R-wave is detected.
NOTE
z
During synchronized cardioversion, it is important to continue to hold the shock button (or the paddle’s
Shock buttons) until the shock is delivered. The equipment shocks with the next detected R -wave.
8.5.2 Delivering Additional Synchronized Shocks
If additional synchronized shocks are indicated, perform the following steps:
1. Make sure the equipment is still in Sync mode, as indicated by the presence of the Sync message in the
defibrillation information area.
2. Repeat Steps 4 to 9 as described above.
If [ Sync after Shock ] is set to [ Yes ], the equipment remains in the sync mode after a shock is delivered; if set to [ No ], the
equipment exits the sync mode and enters the asynchronous defibrillation mode after a shock.
8.5.3 Disabling the Sync Function
To switch off the Sync function, press the [ Sync Off ] soft key to enter the Manual Defib mode. .
