It is up to the user to ensure that any applicable regulations regarding the installation and operation of the monitor are observed. The Information regarding circuit diagrams, board layouts and replacement parts is contained in the Operation and Maintenance Manual. For instructions on how to obtain the Operation Manual or the Operation and Maintenance Manual please contact customer service personnel at IVY Biomedical Systems, Inc. The model 450C is to be operated by qualified personnel only. Using This Manual We recommend that you read this entire manual before operating the equipment. This manual is written to include all parameters for a fully configured monitor. If the configuration of your monitor does not include all parameters, menu selections and display data for those parameters will not appear on your monitor. Use the Monitor Description section for general descriptions of controls and displays. For details on monitoring each parameter, refer to the section of the manual dealing with the appropriate parameter. NOTE: If the monitor beeps when you press a key, it indicates an invalid selection for the current mode or function. Boldface type is used in text to refer to the labeling on user controls. Special brackets [ selections used with the programmable keys.

SAFETY

SAFETY

Electrical This product is intended to be operated from a mains power source of nominally 100 to 230 V ~, 47-63 Hz, or from its internal battery. WARNING: To prevent electrical hazards to all personnel, this monitor must be properly grounded. Connect the monitor only to a three-wire, grounded, hospital grade receptacle. The three-conductor plug must be inserted into a properly wired three-wire receptacle; if a three-wire receptacle is not available, a qualified electrician must install one in accordance with the governing electric code. WARNING: Do not under any circumstances remove grounding conductor from the power plug. WARNING: The power cable supplied with this equipment provides for this protection. Do not attempt to defeat this protection by modifying the cable or by using ungrounded adapters or extension cables. The power cord and plug must be intact and undamaged. To disconnect the equipment from the mains power unplug the power cord. WARNING: Do not connect to an electrical outlet controlled by a wall switch or dimmer. WARNING: If there any doubt about the integrity of the protective earth conductor arrangement, operate the monitor on internal battery power until the AC power source protective conductor is fully functional. WARNING: Do not place the monitor in any position that may cause it to fall on the patient. Do not lift the monitor by the power supply cord or patient cable, use only the handle on the monitor. WARNING: Electric shock hazard! Do not remove covers or panels. Refer service to qualified service personnel. WARNING: To avoid electrical shock, disconnect the monitor from its power source before changing fuses. Replace fuses only with same type and rating (1.6ASB, Metric 5x20mm, 250V). WARNING: Do not clean monitor while it is on and/or plugged into a power source. WARNING: If unit is accidentally wet, discontinue use until dry and then test unit for proper operation before reuse on patient. WARNING: This unit uses a common isolation path for the ECG leads. Do not connect any non-isolated accessories to the ECG input when connected to a patient, as this may compromise the safety of the unit. When attached to other devices, insure that the total chassis leakage currents of all units do not exceed 300 μA.

Explosion DANGER: Explosion hazard! Do not use this equipment in the presence of flammable anesthetics or other flammable substance in combination with air, oxygen-enriched environment or nitrous oxide.

SAFETY

Patient Connections Patient connections are electrically isolated. For all connections use isolated probes. Don’t let patient connections contact other conductive parts, including earth. See instructions for patient connections in this manual. Carefully route patient cables to reduce the possibility of patient entanglement or strangulation. Leakage current is limited internally by this monitor to less than 10 μA. However, always consider cumulative leakage current that can be caused by other equipment used on the patient at the same time as this monitor. To ensure that the leakage current protection remains within the specifications, use only the patient cables specified in this manual. This monitor is supplied with protected lead wires. Do not use cables and leads with unprotected lead wires having exposed conductors at the cable end. Unprotected lead wires and cables may pose an unreasonable risk of adverse health consequences or death. If an alarm condition occurs while the alarms are set to off, the only alarm indication will be visual displays and symbols related to the alarm condition.

MRI The model 450C should not be used within the magnetic field during Magnetic Resonance Imaging.

Pacemakers Rate meters might continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely on rate meter alarms. Keep pacemaker patients under close surveillance.

Electrosurgery To avoid the potential of electrosurgery burns at monitoring sites, ensure proper connection of the electrosurgery return circuit as described by manufacturer’s instructions. If improperly connected, some electrosurgery units might allow energy to return through the ECG electrodes, SpO2 sensors, Pressure Transducers, EtCO2 sensors, and Temperature probes. To further reduce the potential of burns, locate the SpO2 sensors, Pressure Transducers, EtCO2 sensors, and Temperature probes as described in the manufacturer’s instructions.

Defibrillation Protection This equipment is protected against 360 J discharge and electrosurgery potentials. The monitor is internally protected to limit current through the electrodes to prevent injury to the patient and damage to the equipment as long as the defibrillator is used in conformance with the manufacturer’s instructions.

EMC This equipment has been certified to be protected to emissions and immunity according to IEC-60601-1-2.

For monitors used in Australia For continued Defibrillation protection and proper Respiration monitoring use only patient cables with 1kΩ series resistors. It is important to use only patient cables with 1kΩ series resistors because the respiration circuit is tuned to operate with series resistors. For 3-lead configuration monitors, use 3-lead patient cable with 1kΩ series resistors. Ivy reorder no. 590197. For 5-lead configuration monitors, use 5-lead patient cable with 1kΩ series resistors.

MONITOR DESCRIPTION

MONITOR DESCRIPTION The Model 450C Patient Monitor is a color four-trace adult, pediatric, or neonatal monitor for: ECG Heart Rate Respiration - Impedance EtCO2 Two Invasive Pressures Two Temperatures Non-Invasive Blood Pressure (NIBP) Pulse Oximetry The Model 450C is available in several configurations, therefore, not all parameters are included in all monitors. The use of the Model 450C is restricted to one patient at a time. The monitor is intended for use in emergency room, recovery room, intensive care, and surgical applications and transport with 2.5 hours battery operation. The Model 450C is suitable for use in presence of electrosurgery. The Model 450C is not intended for use with any other physiological monitoring unit. An optional integral recorder is available. Recorder settings are made through the monitor menus. Battery operation consists of two rechargeable lead acid cells. The display has four traces available and alphanumeric displays for data, alarms, and user information, such as menus. The monitor automatically senses which devices are connected and acquires and displays data for the parameters being used. Data for parameters not being used is not displayed. Areas for display of those parameters are left blank.
