Non-Explosion Proof
DANGER
Never operate the equipment in the presence of flammable anesthetics,
high concentration of oxygen, or inside hyperbaric chamber. Also, do
not operate the equipment in an environment in which there is a risk of
explosion.
Explosion or fire may result.
Defibrillation Safety
WARNING
l
l
When defibrillating, keep away from the electrodes or medicament
applied to the patient chest. If this is not possible, remove the
electrodes or medicament before defibrillating.
If the defibrillator paddles directly contact the electrodes or
medicament, electrical shock may result by the discharged energy.
l
When defibrillating, make sure that the electrodes, sensor cables, or
relay cables are firmly connected to the device.
Contacting the metal part of the disconnected cable may result in
electrical shock by the discharged energy.
When defibrillating, do not touch the patient and the metal part of the
device or cables.
Electric shock may result by the discharged energy.
Electrosurgery Safety
WARNING
The monitoring system contains protection against interference
generated by electrosurgical instruments. However, operating
conditions, surgery site with respect to the location of ECG electrodes,
or the type of instrument used, may cause noise on the ECG. The
noise is generated at the tip of an electrical knife and is difficult to
completely eliminate because of the frequency components of the ECG.
To reduce electrosurgical interference, take the following precautions:
Location
Locate the electrosurgical unit as far as possible from this unit and
the patient cable. This will help reduce interference on the ECG
through the monitor or cables.
Power Supply
Connect the electrosurgical unit to a power supply that is different
from that of the monitor. This will help prevent interference through
the power cable.
Electrode Placement
The amount of interference is considerably different depending on
the electrode position and surgery site. Place the ECG electrodes
as far away as possible from the surgery site and the ground plate.
Do not place electrodes in the path between the surgery site and the
ground plate. If the electrodes are placed in this path, the amount of
interference will be quite large. Position (+) and (–) electrodes as
close as possible to each other.
Ground Plate
When using electrosurgical instruments, make sure the contact
between the patient and the ground plate is secure. If the
connection is incomplete, the patient may suffer a burn at the
electrode site.
