Electrosurgery and Defibrillation Safety
The monitor is protected against high-frequency interference
from electrosurgery units and discharges from defibrillators, as
well as against 50- and 60-Hertz power line interference.
WARNIN G: The monitor is not protected against high-
frequency interference from diathermy equipment.
CAUTION: During Electrosurgery, observe the following guide-
lines to minimize ESU interference and provide maximum user and
patient safety:
! Use the ESU block to connect ECG cables.
! Keep all transducers and intermediate cables off of earth
ground and away from the ESU knife and return wires.
! Use the SpO
2
pulse rate instead of the ECG to determine the
heart rate.
! Use rectal temperature probe sheaths to cover any internally
placed temperature sensors.
! Always use the accessories designed for ESU environments.
! If pacer detection is on, the ESU interference may be detected
as pacer spikes displayed on the ECG.
Pacemaker Safety
WARNIN G: Rate meters may continue to count the
pacemaker rate during occurrences of cardiac arrest or
some arrhythmias. Do not rely entirely upon rate meter
alarms. Keep pacemaker patients under close surveil-
lance.
WARNING: Make sure that pacer detection is turned off
for patients without pacemakers, and turned on for
patients with pacemakers.
