Safety: General Information
General Information General Use If the monitor 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 EN60601-1-1. Disposable devices are intended for single use only. They should not be reused. Periodically, and whenever the integrity of the monitor is in doubt, test all functions. Refer to the “Maternal/Fetal Monitoring, Clinical Applications Manual” for information concerning the limitations of internal and external fetal heart rate monitoring techniques.
Responsibility of the Manufacturer GE Medical Systems Information Technologies is responsible for the effects on safety, reliability, and performance if:
assembly operations, extensions, readjustments, modifications, or repairs are carried out by persons authorized by GE Medical Systems Information Technologies;
the electrical installation of the relevant room complies with the requirements of appropriate regulations; and
the monitor is used in accordance with the instructions of use.
Responsibility of the User This device is intended for use by clinical professionals who are expected to know the medical procedures, practices, and terminology required to monitor obstetrical patients. This manual documents all possible parameters available in the 250 Series monitor. It is the responsibility of each hospital to ensure that the Labor and Delivery staff is trained in all aspects of the selected model. The 250 Series monitor is only one clinical indicator of fetal status during labor. The monitor is designed to assist the perinatal staff in assessing the status of a patient. The monitor does not replace observation and evaluation of the mother and fetus at regular intervals, by a qualified care provider, who will make diagnoses and decide on treatments or interventions. Visual assessment of the monitor display and strip chart

Safety: Definitions of Terminology
must be combined with knowledge of patient history and risk factors to properly care for the mother and fetus.
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 monitor. Be sure to read the other chapters because there are additional warnings and cautions which relate to specific features of the monitor. When grouped, warnings and cautions are listed alphabetically and do not imply any order of importance.
Definitions of Terminology
Danger
A DANGER notice indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
Warning
A WARNING indicates a potentially hazardous situation which, if not avoided, could result in 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 circumstance that renders the use of a remedy or the carrying out of a procedure inadvisable, usually because of a risk.

Safety: Monitor Contraindications, Warnings, and Precautions
Definitions of Terminology Danger
A DANGER notice indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
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.
Monitor Contraindications, Warnings, and Precautions Warnings WARNINGS ACCIDENTAL SPILLS-In the event that fluids are accidentally spilled on the monitor, take the monitor out of operation and inspect for damage. APPLICATION-This monitor 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 monitor is to plug the electrode leads into the patient cable which in turn connects to the monitor. The monitor 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-During defibrillation, all personnel must avoid contact with the patient and monitor to avoid a dangerous shock hazard. In addition, proper placement of the paddles in relation to the electrodes is required to minimize harm to the patient. DEFIBRILLATION PROTECTION-When used with the GE Medical Systems Information Technologiesrecommended accessories, the monitor is protected against the effects of defibrillator discharge. If monitoring is disrupted by the defibrillation, the monitor will recover. 5HYLVLRQ(

Safety: Monitor Contraindications, Warnings, and Precautions
ELECTRICAL SHOCK-To reduce the risk of electrical shock, do not remove monitor cover. Refer servicing to qualified personnel. ELECTROMAGNETIC INTERFERENCE-Be aware that strong electromagnetic fields may interfere with monitor operation. Interference prevents the clear reception of signals by the monitor. 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 monitor signals. If you feel interference is affecting the monitor, contact your Service Representative to check the monitor in your environment. Refer to“Electromagnetic Interference” on page 1-9 for additional information.
WARNINGS ELECTROSURGERY-The monitor 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. EQUIPMENT USE-The use of this equipment is restricted to one patient at a time. 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. INOPERABLE MECG-The MECG trace is not visible during a MECG LEADS OFF condition or an overload (saturation) of the front-end amplifier during differential input voltage of more than ± 300mV. 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 monitor 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’
