General Information
Defibrillator Complications
Inappropriate defibrillation or cardioversion on a patient (e.g., with no malignant
arrhythmia) may precipitate ventricular fibrillation, asystole, or other dangerous
arrhythmias. Defibrillation without proper application of paddle electrolyte
gel may be ineffective and cause burns, particularly when repeated shocks
are necessary.
Defibrillator Output Energy
The ZOLL PD 1400 delivers up to 360 joules into a 50 ohm impedance. The
energy delivered through the chest wall, however, is controlled by skin imped-
ances. An adequate amount of electrolyte gel must be applied to the paddles
and a force of 10-1 2 kilograms must be applied to each paddle in order to
minimize skin impedance. If multi-function electrodes are used, make sure
that they are properly applied. (See Chapter 3)
MONITOR
This product contains a non-fade monitor for observation of the patient's cardiac
FUNCTION
rhythm. The monitor displays the ECG in moving trace mode at 25 mmlsec for a
period of 3.4 seconds.
Also displayed on the monitor are:
4 heart rate, derived from measuring R to R intervals
4 lead selections
-
I, 11, Ill, PADDLES, or ELECTRODES
4 ECG size
-
.5, 1.0, 1.5, 2.0, 3.0 cm/mV
4 pacemaker output in milliamps
4 defibrillator output in joules
4 other operational prompts, messages, and diagnostic codes
RECORDER
The hard copy recorder is used to document events. The recorder normally
FUNCTION
operates in the delay mode (6 seconds) to insure capture of critical ECG informa-
tion. It may be activated manually by pressing the RECORDER ONIOFF button. It
will be activated automatically whenever the defibrillator discharge buttons have
been pressed or a Heart Rate Alarm activates. The recorder may also be config-
ured not to print during these events. (See Recorder Configuration, Chapter 2 for
more information.)
