Using Paddles for Performing Synchronized Cardioversion
To start cardioversion, perform the following steps.
1 Turn the Energy Select control to Monitor On.
2 Select the desired ECG lead by pressing Lead Select.
3 Press Sync once to place the HP CodeMaster 100 in Sync mode. The message
SYNC
appears on the display.
If you select paddles as the ECG source, the message
USE LEADS
will appear
on the display. Although the HP CodeMaster 100 will allow synchronized shock
in paddles ECG mode, leads mode is recommended. Artifact induced by
moving the paddles may resemble an R-wave and trigger defibrillator shock.
You can perform cardioversion in Autogain mode. Always inspect the displayed
ECG before delivering the counter shock. Verify that an R-wave marker (indi-
cating shock point) appears only with each R-wave. If a marker dot does not
appear, or if a marker dot is viewed on the T-wave segment of the ECG, follow
these instructions:
•Adjust the ECG size by pressing ECG Size until the marker dot appears only with
each R-wave.
•Select a different lead or adjust the electrode placement, if necessary, to improve
ECG R-wave quality.
4 Select the desired energy level with the Energy Select control.
