Safety: General Information
General Information
General Use
If any equipment is cold to the touch or below ambient temperature,
allow it to stabilize before use.
To ensure patient safety, use only parts and accessories manufactured or
recommended by GE Medical Systems Information Technologies. Parts
and accessories used shall meet the requirements of IEC 601.1.1.
Disposable devices are intended for single use only. They should not be
reused.
Periodically, and whenever the integrity of the equipment is in doubt,
test all functions.
Refer to the "Maternal/Fetal Monitoring Operator’s Manual" for
information concerning the limitations of internal and external fetal
heart rate monitoring techniques.
Responsibility of the Manufacturer
GE Medical Systems Information Technologies (hereinafter Information
Technologies) is responsible for the effects on safety, reliability, and
performance if:
n assembly operations, extensions, readjustments, modifications, or
repairs are carried out by persons authorized by Information
Technologies;
n the electrical installation of the relevant room complies with the
requirements of appropriate regulations; and
n the equipment is used in accordance with the instructions for use.

Safety: Definitions of Terminology
Definitions of Terminology
Six types of special notices are used throughout this manual. They are:
Danger, Warning, Caution, Contraindication, Important, and Note. The
warnings and cautions in this safety section relate to the equipment in
general and apply to all aspects of the equipment. Be sure to read the
other chapters because there areadditional warnings and cautions which
relate to specific features of the equipment.
When grouped, warnings and cautions are listed alphabetically and do
not imply any order of importance.
Table 1-1. Definitions of Terminology
Danger A DANGER notice indicates an imminently hazardoussituationwhich,ifnotavoided,willresult
in death or serious injury.
Warning A WARNING indicates a potentially hazardous situationwhich, ifnot avoided,could resultin death
or serious injury.
Caution
A CAUTION indicates a potentially hazardous
situation which, if not avoided, may result in minor
or moderate injury. Cautions are also used to
avoid damage to equipment.
Contraindication
A CONTRAINDICATION describes any special
symptom or circumstancethat renders theuse of a
remedy or the carrying out of a procedure
inadvisable, usually because of a risk.
Important An IMPORTANT notice indicates an emphasized note. It is something you should be particularly
aware of; something not readily apparent.
Note A NOTE indicates a particular point of information;
something on which to focus your attention.

Safety: Equipment Safety Information
Equipment Safety Information
Warnings
:$51,1*6
ACCIDENTAL SPILLS—In the event that fluids are
accidentally spilled on the equipment, take the
equipment out of operation and inspect for damage.
APPLICATION—This equipment is not designed for
direct cardiac connection.
CONDUCTIVE CONNECTIONS—Avoid making any
conductive connections to applied parts (patient
connection) which are likely to degrade safety.
CONDUCTIVE PARTS—Ensure that the conductive
parts of the lead electrodes and associated connectors do
not contact other conductive parts including earth.
CONNECTIONS—The correct way to connect a patient
to the transmitter is to plug the electrode leads into the
patient cable which in turn connects to the
transmitter. The receiver is connected to the wall
socket by the power cord. Do not plug the electrode
leads into the power cord, a wall socket, or an extension
cord.
DEFIBRILLATION—This equipment is not designed for
use with defibrillators.
ELECTRICAL SHOCK—To reduce the risk of electrical
shock, do not remove equipment covers. Refer servicing
to qualified personnel.
ELECTROMAGNETIC INTERFERENCE—Be aware
that strong electromagnetic fields may interfere with
equipment operation. Interference prevents the clear
reception of signals by the device. If the hospital is close
to a strong transmitter such as TV, AM or FM radio,
police or fire stations, a HAM radio operator, an airport,
or cellular phone, their signals could be picked up as
signals by the equipment. If you feel interference is
affecting the equipment, contact your Service

ELECTROSURGERY—The equipment is not designed
for use with high-frequency surgical devices. In addition,
measurements may be affected in the presence of strong
electromagnetic sources such as electrosurgery
equipment.
EXPLOSION HAZARD—Do not use this equipment in
the presence of flammable anesthetics or inside an
oxygen tent.
GROUNDING—Do not defeat the three-wire grounding
feature of the power cord by means of adaptors, plug
modifications, or other methods. A dangerous shock
hazard to both patient and operator may result.
INSTRUCTIONS—For continued and safe use of this
equipment, it is necessary to follow all listed instructions.
However, the instructions provided in this manual in no
way supersede established medical procedures
concerning patient care. The device does not replace
observation and evaluation of the patient, at regular
intervals, by a qualified care provider who will make
diagnoses and decide on treatments and interventions.
INTERFACING OTHER EQUIPMENT—Monitoring
equipment must be interfaced with other types of medical
equipment by qualified biomedical engineering
personnel. Be certain to consult manufacturers’
specifications to maintain safe operation.
LEAKAGE CURRENT TEST—The interconnection of
auxiliary equipment with this device may increase the
total leakage current. When interfacing with other
equipment, a test for leakage current must be performed
by qualified biomedical engineering personnel before
using with patients. Serious injury or death could result
if the leakage current exceeds applicable standards. The
use of accessory equipment not complying with the
equivalent safety requirements of this equipment may
lead to a reduced level of safety of the resulting system.
Consideration relating to the choice shall include: use of
the accessory in the patient vicinity; and evidence that
the safety certification of the accessory has been
performed in accordance with the appropriate IEC 601.1
and/or IEC 601.1.1 harmonized national standard.

LINE ISOLATION MONITOR TRANSIENTS—Line
isolation monitor transients may resemble actual cardiac
waveforms, and thus cause incorrect heart rate
determinations and alarm activation (or inhibition).
MRI USE—Do not use the equipment during MRI
scanning; conducted current could potentially cause
burns.
PATIENT CABLES AND LEADWIRES—Do not use
patient cables and electrode leads that permit direct
connection to electrical sources. Use only “safety”cables
and leadwires. Use of non-safety patient cables and lead
wires creates risk of inappropriate electrical connection
which may cause patient shock or death.
PACEMAKER PATIENTS—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
surveillance. Refer to your monitor’s operator’s manual
for disclosure of the pacemaker pulse rejection capability.
SIMULTANEOUS DEVICES—Do not simultaneously
connect more than one device that uses electrodes to
detect ECG and/or respiration to the same patient. Use
of more than one device in this manner may cause
improper operation of one or more of the devices.
STRANGULATION—Make sure all patient cables,
leadwires, and tubing are positioned away from the
patient’s head to minimize the risk of accidental
strangulation.

ANNUAL SERVICING—For continued safety and
performance of the equipment, it is recommended that
the calibration, accuracy, and electrical safety of the
equipment be verified on an annual basis by an
Information Technologies Service Representative.
DAILY INSPECTION—It is essential that the
equipment and accessories be inspected prior to every
use.
ENVIRONMENT—The performance of the equipment
has not been tested in certain areas, such as x-ray and
imaging suites. The equipment is not recommended for
use in these environments.
PERFORMANCE—Report all problems experienced with
the equipment. If the equipment is not working properly,
contact your Service Representative for service. The
equipment should not be used if it is not working
properly.
