Synchronized Cardioversion Procedure
9650-0912-01 Rev. N ZOLL R Series Operator’s Guide 5–3
Attach hands-free therapy electrodes according to instructions on the electrode packaging and
as described in “Therapy Electrode Application” on page 3-7.
Ensure that the therapy electrodes are making good contact with the patient’s skin and are not
covering any part of any other electrodes.
Connect the hands-free therapy electrodes to the OneStep cable if not preconnected.
If therapy electrodes are not making good contact with the patient’s skin, the unit issues the
messages CHECK PADS and POOR PAD CONTACT and does not allow delivery of energy. If a
short circuit exists between the electrodes, the unit issues the message DEFIB PAD SHORT.
An ECG LEAD OFF condition prevents synchronized discharge if leads are selected as the
ECG source. This condition does not prevent the use of the defibrillator; it simply prevents use
in a synchronized manner.
If paddles are being used for synchronized cardioversion, refer to “Emergency Defibrillation
Procedure with Paddles” on page 3-1 for preparing paddles, applying paddles, charging the
defibrillator, and delivering a shock. Note, however, that synchronized discharge with paddles
as an ECG source is discouraged since the artifact induced by moving the paddles may
resemble an R-wave and trigger defibrillator discharge at the wrong time.
1 Select DEFIB
Turn the Mode Selector to DEFIB. Select the desired energy using the up and down arrow keys
on the front panel (or sternum paddle if using paddles).
Press the Sync On/Off softkey
Your system will be in Sync mode once you press the Sync On/Off softkey if your R Series is
not configured to support Remote Sync. However, if your R Series is configured to support
Remote Sync, pressing the Sync On/Off softkey will cause two other softkeys to be displayed:
Remote Sync and Sync. Press the Sync softkey to enter Sync mode.
The selected energy level is displayed on the monitor.
A Sync marker (
) appears on the monitor above each detected R-wave to indicate where
discharge will occur.
