ABOUT THIS MANUAL This Operating Manual contains all of the information you need to set up and operate the Aspect™ Medical Systems’ BIS VIEW™ Monitoring System (Figure 3). 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 VIEW 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 VIEW system, please familiarize yourself with the safety information provided in this section.

i

INTRODUCING THE BIS VIEW MONITORING SYSTEM Introduction The BIS VIEW 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 VIEW 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 VIEW monitor display consists of: • • • • •

The current BIS number Trend graph of BIS values over time Raw EEG waveforms in real time Various signal quality indicators (EMG, SQI, SR) 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. Easy-to-use menus allow the user to change the data display and review stored data.

ii

Important Information about Using BIS Monitoring BIS monitoring systems are intended for use under the direct supervision of a licensed healthcare practitioner or by personnel trained in their proper use. They are 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 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 BIS 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 the BIS in conjunction with other available clinical signs. Reliance on the 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 Aspect Representative. For more information, please contact Aspect Medical Systems at (800) 442-2051. If you require additional information on the use of BIS, please contact Aspect Medical Systems Clinical Support at 800-442-8655 or 617-559-7655 if calling from outside of the USA.

SECTION 1 SAFETY PRECAUTIONS ______________________________________________________________________ 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 THREEPRONG 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 THREE-SLOT GROUNDED OUTLET BEFORE ATTEMPTING TO OPERATE THE MONITOR. IF THE INTEGRITY OF THE EXTERNAL PROTECTIVE EARTH GROUND IS IN DOUBT, THE BIS VIEW 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 HIGHFREQUENCY SURGICAL EQUIPMENT, THE SENSOR OR ELECTRODES SHOULD NOT BE LOCATED BETWEEN THE SURGICAL SITE AND THE ELECTRO-SURGICAL UNIT RETURN ELECTRODE. THE SENSOR MUST NOT BE LOCATED BETWEEN DEFIBRILLATOR PADS WHEN A DEFIBRILLATOR IS USED ON A PATIENT CONNECTED TO THE BIS VIEW SYSTEM.

Cautions

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 the BISx for any reason. The seal to prevent liquids from entering the BISx may be damaged if opened. 1-3

SECTION 1 SAFETY PRECAUTIONS ______________________________________________________________________ The BIS VIEW system has been designed to operate with a BIS sensor. The sensor is a silver/silver chloride electrode array that utilizes Aspect's patented Zipprep™ technology and uses a proprietary connector. Use of other electrodes is not recommended. Do not remove drive while export is in progress. 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). Check the battery periodically by operating a BIS VIEW 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 (e.g., more than 1 month) it may be necessary to cycle (charge, then discharge) the battery a few times to get full charge capacity. If the BIS VIEW monitor fails to operate reliably from the battery for approximately 45 minutes, battery replacement is required. The BIS VIEW 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 Aspect Medical Systems, Inc. or the local distributor for a replacement battery: Aspect 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. The BIS VIEW system complies with the electromagnetic compatibility requirements of IEC 60601-1-2. Operation of this device may affect or be affected by other equipment in the vicinity due to electromagnetic interference (EMI). If this occurs: • Increase separation between devices • Re-orient device cabling • Plug devices into separate outlet circuit branches Refer to Section 8.2 “Electromagnetic Compatibility Specifications.” Do not disconnect the BISx during the software update. When connecting or disconnecting BISx, take care not to touch the exposed contacts of either connector. Damage due to electrostatic discharge may result. Using accessories other than those specified may result in increased electromagnetic emissions or decreased electromagnetic immunity of the BIS VIEW Monitoring System.
