SYNC
In sync mode, the unit synchronizes defibrillator discharge with the first detected
R-wave after both discharge buttons are pressed and held down. This mode is
typically used for cardioversion procedures.
The sync button can be used in the defibrillation or the monitor mode.
For synchronized operation, press the sync button once. The "SYNC XXX J" or
"SYNC MONITOR" message appears on the display. A distinctive marker appears
on the monitor with each detected R-wave.
To return to standard defibrillation mode for instant discharge, press the sync
button again.
The ZOLL PD 1400 is designed to leave sync mode and revert to standard
defibrillation mode after discharge.
PACER OUTPUT mA
This switch is used to control the amount of current to the pacemaker electrodes
For conscious patients, it should be gradually increased until capture is recognized.
The output is displayed digitally on the monitor.
PACER RATE ppm
When pacing is selected, this control sets the rate at which the pacemaker will
operate. It must be set above the patient's intrinsic rate in order for the pace
maker to provide stimulation.
4:l BUlTON
This control is used optionally to test for threshold or to determine the underlying
rhythm. When depressed, approximately every 4th beat is a paced beat.
Releasing the control causes the instrument to resume normal operation.
LEAD
Selection of the ECG source is accomplished through the lead button. Pressing
the button sequentially selects and displays each option on the monitor-"I",
"11".
"Ill", "PADDLES" (defibrillator paddles), or "ELECTRODES" (multi-function elec-
trodes). Electrodes or paddles is automatically selected when the instrument
powers up in defib on or monitor on. Lead II is automatically selected when
the instrument powers up in pacer on. ECG monitoring through multi-function
electrodes is accomplished by selecting "ELECTRODES." ECG monitoring
through the paddles is accomplished by selecting "PADDLES." Paddles monitor
ing is not available in pacer on mode.
