Defib/Pacer Solutions
Problem
Defibrillator will not charge
(beeps intermittently) when
CHARGE key is pressed.
Defibrillator beeps intermittently
when attempting to charge the
internal paddles.
Patient's skin burns during
pacing.
Insufficient ECG waveform
during defibrillation or pacing.
Discomfort or pain during pacing.
Unable to obtain ventricular
capture.
Possible Causes
Defibrillator cable is either
disconnected or defective.
Internal paddle cable is either
disconnected or defective.
Energy selected exceeds 50 joules.
Improper electrode to skin adhesion
or use of dry or otherwise defective
electrodes.
Pacing current may be set too high.
Incorrect ECG electrode placement.
Defibrillator ECG source is set to
PADDLES.
Patient and/or paddle motion.
Excessive pacing current.
External pacer is either not in
DEMAND mode or the pace rate is
too low.
10-7
power.
Action/Solution
Ensure that defibrillator cable
is properly connected to the
defibrillator behind the Prism
monitor. If problem persists,
replace defibrillator cable.
Ensure that internal paddle
cable is properly connected to
defibrillator behind the Prism
monitor. If problem persists,
replace internal paddle cable.
Ensure that energy selected is
not more than 50 joules (max.
setting for internal paddles).
Ensure that disposable
defibrillator/ pace electrodes
are not outdated.
Replace electrodes that are
dry or defective.
If possible, reduce pacing
current.
Apply standard 3-lead ECG
cable with proper electrodes
to obtain ECG waveform.
Set defibrillator ECG source
to LEADS with ECG
SOURCE key. Then connect
a standard 3-lead ECG cable
with proper electrodes.
If possible, reduce patient
and/or paddle motion.
If possible, reduce pacing
current. If high pacing current
is warranted for capture,
sedation with analgesic may
be required.
Ensure that pacer is set to
DEMAND mode and pace
rate is higher than that of the
patient. Also ensure that
sufficient pacing current is
being delivered to patient.
