Table of Contents ID 30
Before You Begin Brief Description User Guide This User Guide is designed to enhance your knowledge of Compumedics Limited E-Series EEG, E-Series EEG/PSG, Siesta and Safiro data acquisition systems and the ProFusion EEG data acquisition and analysis software. It contains information and procedures required to record EEG studies, then review, analyse and archive the study data. Software The ProFusion EEG software is a Microsoft Windows-based package used to configure, record and replay digitised patient neurological signals acquired during the recording of EEG studies. The signals may be acquired by the E-Series EEG, E-Series EEG/PSG, Siesta or Safiro System hardware, displayed on a Recording workstation and stored on the workstation or other medium. This data may be used to assist trained physicians, clinicians or technologists in the investigation of neurological disorders. Note that the specifications for the ProFusion EEG software can change at any time without prior warning. Hardware This User Guide contains information on the E-Series EEG System hardware. For information on the E-Series EEG/PSG, Siesta or Safiro Systems, refer to their respective user guides. The EEG System hardware comprises the input connections from the patient, the recording hardware and the peripherals used to acquire and store patient neurological data for later replay and analysis. Recording is performed on a Recording workstation. Replay and analysis can be performed on the Recording workstation or on other workstations using the data collected during the patient study. Access to archived data and printer facilities can be provided to other workstations via a network. Note that the specifications and hardware arrangements can change at any time without prior warning. Indications for Use The EEG System is intended to be used as an aid in the diagnosis of neurological disorders and should only be used under the supervision of a physician, technologist or clinician. It is a data recording system, and will not prevent or restore the interruption or loss of any physiological system. EEG studies should only be carried out under the recommendation of a physician. The ProFusion EEG software is intended for use by persons trained in professional health care.

Safety and Effectiveness Considerations General Be sure to read, understand and follow the instructions in this User Guide and others that come with the E-Series EEG, E-Series EEG/PSG, Siesta and Safiro Systems, and their accompanying accessories. For all third party equipment used with these systems, follow all of the manufacturer's recommendations and instructions. Place EEG System components on a sturdy and level surface. Do not place any component on the floor or in the bed with the patient. If a system component is dropped, discontinue using it until it is determined that the component can be safely operated. Contact Compumedics Product Support or your authorised representative for assistance. EEG Systems should be used only in hygienic locations. Cleaning Always unplug the components from all electrical power sources when cleaning the EEG System hardware or any of its accessories. Unless specified within these instructions, follow the manufacturer's recommendations and instructions for reusing, cleaning, disinfecting, or sterilising electrodes, sensors and monitoring equipment used with the EEG System. Do not autoclave, gas, or pressure sterilise any of the EEG System components. If any liquid is spilled on an EEG System component, discontinue using it until it is determined that the component can be safely operated. Contact Compumedics Product Support or your authorised representative for assistance. Refer to Appendix G “Cleaning and Disinfecting” for more detailed information. Environmental Conditions for Operation, Storage and Transport The EEG System should be used at ambient temperatures between +10°C (+50°F) and +40°C (+104°F), with a non-condensing relative humidity of between 25% and 95%. The EEG System should be stored and transported at temperatures between -20°C (- 4°F) and 50°C (122°F), with a non-condensing relative humidity of between 30% and 95%.

The electrical safety of the EEG system should be regularly tested, at intervals not exceeding 12 months. Contact your Biomedical Engineering department. Such testing should include patient leakage current, enclosure leakage current, earth leakage current and earth resistance. The EEG System should not be used in the presence of flammable liquids or gases, for example: a flammable anaesthetic mixture with air or a flammable anaesthetic mixture with oxygen or nitrous oxide. This may present an explosion hazard.
N
Warning:
Do not allow electrode wires, sensor leads or connecting leads to become tangled, coiled, or crossed, or wrapped around the patient's neck, arms or legs. This condition may cause strangulation.
Electrical shock hazards
N
Warning:
Conductive parts of electrodes and their connectors, including the reference electrodes, should not contact other conductive parts, including earth. This condition will be met if all electrodes have one end connected to the Patient Interface Box and the other end attached to the patient.
N
Warning:
If applied parts from other equipment are attached to the patient, in addition to the electrodes of the EEG System, it is possible for the total patient leakage current to exceed the requirements for type CF applied parts.
N
Warning:
The EEG System is not protected against the effects of a cardiac defibrillator discharge. If a cardiac defibrillator is to be used on a patient, then all EEG electrodes must be disconnected from the patient.
N
Warning:
The cover on the 37-way ‘D’ connector on top of the Patient Interface Box must be securely screwed in position at all times, except when the connector is being used.
N N N
Warning:
Do not use the EEG System if the cover of any component of the EEG System is removed.
Warning:
Do not use in conditions where the EEG System may be exposed to liquids
Warning:
Ensure that medical equipment connected to the DC Inputs socket of the Control Box is IEC 60601-1 compliant.
Use of EEG System During Electrosurgery
N
Warning:
If the EEG System is used to monitor a patient undergoing electrosurgery, take the following precautions to reduce the hazard of burns: • Use only an isolated electrosurgical generator • Use bipolar electrosurgery instead of monopolar electrosurgery • Position the EEG electrodes as far away as possible from the site of electrosurgery
