Preface

About This Manual This Operating Manual contains all of the information you need to set up and operate the Covidien BIS™ Complete Monitoring System. It also includes specific cleaning and test procedures you may occasionally be required to perform. Although this manual is intended for trained medical personnel, it does not assume prior knowledge or experience with operator-programmable medical electronics devices. Keep this Operating Manual with the BIS Complete monitor for use by the operator. This manual is also intended to be a service information manual for service technicians or biomedical engineering personnel. Before attempting to set up or use the BIS Complete system, please familiarize yourself with the safety information provided in this section.

Preface

Introducing the BIS™ Complete Monitoring System Introduction The BIS Complete Monitoring System is a user-configurable patient monitoring system designed to monitor the hypnotic state of the brain based on acquisition and processing of EEG signals. The BIS Complete system processes raw EEG signals to produce a single number, called the Bispectral Index™, or BIS, which correlates with the patient's level of hypnosis. The BIS Complete monitor display consists of: •

The current BIS number

•

Trend graphs of processed EEG parameters

•

Raw EEG waveforms in real time

•

Various signal quality indicators (EMG, SQI)

•

Suppression Ratio (if requested by the user)

•

Burst Count number (when a BIS Extended Use Sensor is in use)

•

Alarm Indicator and Messages

The system performs self-tests to ensure that the monitor and its components are functioning properly and that impedance levels of patient sensors are within acceptable limits. Touch screen menus allow the user to change the data display and review stored data.

BIS™ Complete Monitoring System Operator Manual

Preface

Important Information about Using BIS™ Monitoring The BIS EEG Complete Monitor System is intended for use under the direct supervision of a licensed healthcare practitioner or by personnel trained in its proper use. The system, and all its associated parameters, is intended for use on adult and pediatric patients within a hospital or medical facility providing patient care to monitor the state of the brain by data acquisition of EEG signals. The BIS Index, one of the Complete Monitor output parameters, may be used as an aid in monitoring the effects of certain anesthetic agents; and its usage with certain anesthetic agents may be associated with a reduction in primary anesthetic use and a reduction in emergence and recovery time. Use of the BIS Index for monitoring to help guide anesthetic administration may be associated with the reduction of incidence of awareness with recall in adults during general anesthesia and sedation. BIS is a complex monitoring technology intended for use as an adjunct to clinical judgment and training. Clinical judgment should always be used when interpreting BIS in conjunction with other available clinical signs. Reliance on BIS alone for intraoperative anesthetic management is not recommended. As with any monitored parameter, artifacts and poor signal quality may lead to inappropriate BIS values. Potential artifacts may be caused by poor skin contact (high impedance), muscle activity or rigidity, head and body motion, sustained eye movements, improper sensor placement and unusual or excessive electrical interference. BIS values should also be interpreted cautiously with certain anesthetic combinations, such as those relying primarily on either ketamine or nitrous oxide/narcotics to produce unconsciousness. Due to limited clinical experience in the following applications, BIS values should be interpreted cautiously in patients with known neurological disorders and those taking other psychoactive medications. The BIS education site, www.biseducation.com, offers relevant information and published articles on the clinical use of BIS. In addition, there is a “Monitoring Consciousness Using the Bispectral Index during Anesthesia” Clinician’s Pocket Guide available on the website and through your local Covidien Representative. For more information, please contact Covidien at (800) 442-2051. If you require additional information on the use of BIS, please contact Covidien at 800-442-8655 or 617-559-7655 if calling from outside of the USA.

Safety Precautions

1.1

Warnings Warning • Explosion hazard: do not use the BIS™ Complete system in a flammable atmosphere or where concentrations of flammable anesthetics may occur. • Monitor is not designed for use in mri environment. • Use only the power cord supplied by the manufacturer. Never adapt the plug from the monitor to fit a non-standard outlet. • U.S.A. requirement: for proper grounding, the power receptacle must be a three-wire grounded outlet. A hospital grade outlet is required. Never adapt the three-prong plug from the monitor to fit a two-slot outlet. If the outlet has only two slots, make sure that it is replaced with a threeslot grounded outlet before attempting to operate the monitor. • If the integrity of the external protective earth ground is in doubt, the BIS Complete system shall be operated from its internal battery power source only. • Be sure the monitor is mounted securely in place to avoid personal or patient injury. • When connecting external equipment (e.g., data capture computer), the system leakage current must be checked and must be less than the IEC 60601-1-1 limit. • 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 – Evidence that the safety certification of the accessory has been performed in accordance to the appropriate IEC 60601-1 and/or IEC 60601-1-1 harmonized national standard. • Due to elevated surface temperature, do not place BISX™ in prolonged direct contact with patient’s skin, as it may cause discomfort. • The conductive parts of electrodes or sensor and connectors should not contact other conductive parts, including earth. • To reduce the hazard of burns during use of high-frequency surgical equipment, the sensor or electrodes should not be located between the surgical site and the electro-surgical unit return electrode. • To reduce the hazard of burns during use of brain-stimulating devices (e.g., transcranial electrical motor evoked potential), place stimulating electrodes as far as possible from the BIS sensor and make certain that sensor is placed according to package instructions.

Safety Precautions

Warning • The sensor must not be located between defibrillator pads when a defibrillator is used on a patient connected to the BIS™ Complete system. • To minimize the risk of patient strangulation, the patient interface cable (pic) must be carefully placed and secured. • Shock Hazard: Do not attempt to disconnect the power cord with wet hands. Make certain that your hands are clean and dry before touching the power cord. • Universal precautions shall be observed to prevent contact with blood or other potentially infectious materials. Place contaminated materials in regulated waste container. • Do not mix disinfecting solutions (e.g., bleach and ammonia), as hazardous gases may result. • Electrical Shock Hazard: Do not remove monitor covers during operation or while power is connected to monitor. • Electrical Shock Hazard: The manufacturer's inspection of this apparatus verified that the ground leakage current and the patient safety current were less than the specified limits established by the applicable safety standards. As a matter of safe practice, the institution should conduct periodic tests to verify these currents. • Whenever an event such as spillage of blood or solutions occurs, re-test ground leakage current before further use. • Leakage current must be checked by a qualified biomedical engineering technician whenever instrument case is opened. • Power supply is internally fused. Replace power supply only with Covidien BIS Complete power supply.

Safety Precautions

1.2

Cautions Caution • Read this entire manual carefully before using the monitor in a clinical setting. Do not autoclave the BISX™ or Monitor. Autoclaving will seriously damage both components. • Do not block ventilation inlet holes on the underside of monitor. • Do not open BISX for any reason. The seal to prevent liquids from entering the BISX may be damaged if opened. • Service or repairs must be performed only by qualified biomedical technicians. • The BIS™ Complete system has been designed to operate with a BIS sensor. The sensor is a silver/silver chloride electrode array that utilizes Covidien's patented Zipprep™ technology and uses a proprietary connector. Use of other electrodes is not recommended. • To completely remove power from the unit: put the monitor in Standby mode, disconnect power cord from the power receptacle of the monitor, then remove the battery from the monitor. • Continuous impedance checking may need to be disabled if the 1 nanoampere 128 Hz impedance check signal interferes with other equipment (e.g., evoked potential monitors). • Considerations when using Electro-Convulsive Therapy (ECT) equipment during BIS monitoring: Place ECT electrodes as far as possible from the BIS sensor to minimize the effect of interference. Certain ECT equipment may interfere with the proper function of the BIS monitoring system. Check for compatibility of equipment during patient setup. • Check the battery periodically by operating a BIS Complete monitor that has been disconnected from the wall socket and that has been charged to full capacity (at least 6 hours of charge time). After long periods of storage, charge the battery for 6 hours to assure full capacity. If the BIS Complete monitor fails to operate reliably from the battery for approximately 45 minutes, battery replacement is required. • The BIS Complete monitor contains an internal Lithium ion battery. The battery must be removed by a qualified service technician and disposed of or recycled in accordance with the national laws of the country. Contact Covidien or the local distributor for a replacement battery: Covidien part number 186-0208. • Avoid liquid ingress to the Patient Interface Cable. Contact of fluids with the PIC sensor connector can interfere with PIC performance. Service or repairs must be performed only by qualified biomedical technicians.
