Safety The following list contains general warnings and cautions you should know before installing, maintaining or servicing the system. Warnings and cautions specific to the use of the system can be found in the User’s Guide and User’s Reference Manual.

1.2.1

Safety precautions

Warnings WARNING

A WARNING indicates a situation in which the user or the patient may be in danger of injury or death. Power connection • Use only hospital-grade grounded power outlets and power cord. Do not remove the grounding pin from the power plug.

•

Use only an intact power cord. Replace the power cord if it is cracked, frayed, broken or otherwise damaged.

• • •

Do not apply tension to the power cord otherwise the cord may get damaged. Do not use extension cords or adapters of any type. Before starting to use the system, ensure that the whole combination complies with the international standard IEC 60601-1-1 and with the requirements of the local authorities.

Installation • Keep the monitor horizontal when the Compact Airway Module is used. Tilting the monitor may cause erroneous results in the Compact Airway Module’s readings and damage the module.

• • •

The monitor or its components should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, the monitor and its components should be observed to verify normal operation in the configuration in which it will be used. Pins of connectors identified with the ESD warning symbol should not be touched. Connections should not be made to these connectors unless ESD precautionary procedures are used. For details, see section ”ESD precautionary procedures.” After transferring or reinstalling the monitor, always check that it is properly connected and all parts are securely attached. Pay special attention to this in case of stacked mounting.

Laser radiation • When using the ARK Barcode Reader, N-SCAN, do not stare into the beam. The N-SCAN is a Class 2 laser product.

External connection • Do not connect any external devices to the monitor other than those specified. Fuse replacement • Replace a fuse only with one of the same type and rating. Explosion hazard • Do not use the monitor in the presence of flammable anesthetics.

9 Document no. M1027807

Datex-Ohmeda S/5 Anesthesia and Critical Care Monitors

Patient safety • Do not perform any testing or maintenance on the monitor while it is being used on a patient. • PACEMAKER PATIENTS: The impedance respiration measurement may cause rate changes in Minute Ventilation Rate Responsive Pacemakers. In this case, set the pacemaker rate responsive mode off or turn the monitor impedance respiration measurement off.

• •

Never install the monitor or the displays so that they are above the patient. The monitor must not be used without manufacturer approved mounting attached.

Cleaning and service • Only trained personnel with proper tools and test equipment should perform the tests and repairs described in this manual. Unauthorized service may void the monitor warranty.

•

Turn the power off and unplug the power cord before cleaning or service. Completely remove any moisture before reconnecting the power cord to the mains outlet.

•

Do not touch any exposed wire or conductive surface while any cover is removed and the monitor is energized. The voltages present can cause injury or death.

•

Pins of connectors identified with the ESD warning symbol should not be touched. Connections should not be made to these connectors unless ESD precautionary procedures are used. For details, see 1.2.2. ESD precautionary procedures.

•

Always perform an electrical safety check and a leakage current test on the monitor after service.

Accessories • Use only accessories, including mounts and batteries, and defibrillator-proof cables and invasive pressure transducers approved by GE Healthcare. For a list of approved supplies and accessories, see the “Supplies and Accessories” catalog delivered with the monitor. Other cables, batteries, transducers and accessories may cause a safety hazard, damage the equipment or the system, result in increased emissions or decreased immunity of the equipment or system or interfere with the measurement. Protection against cardiac defibrillator discharge is due in part to the accessories for pulse oximetry (SpO2), temperature (T) and invasive pressure (P) measurement.

•

Single use accessories are not designed to be reused. Reuse may cause a risk of contamination and affect the measurement accuracy.

Cautions CAUTION

A CAUTION indicates a condition that may lead to equipment damage or malfunction. Installation • Leave space for air circulation to prevent the monitor from overheating. • Ensure that the module is properly orientated (i.e. module release latch facing downward) before insertion.

•

Before connecting the power cord to the mains outlet, check that the local voltage and frequency correspond with the rating stated on the device plate on the rear panel of the monitor. See instructions for different displays in section “Displays”.

•

Before use • Allow two minutes for warm-up and note any error messages or deviations from normal operation.

• •

Clean the rear panel fan dust filters once a month or whenever necessary. Do not connect a sampling line to the female Patient Spirometry connector while the other end of the sampling line is connected to the D-fend water trap. The pressure in the gas sampling system may cause damage to the PVX unit pressure transducers.

Autoclaving and sterilizing • Do not autoclave any part of the monitor. • Do not gas sterilize the modules. Cleaning and service • Do not use hypoclorite, ammonia-, phenol-, or acetone based cleaners. These cleaners may damage the monitor surface.

•

Do not immerse any part of the device in any liquid, or allow liquid to enter the monitor or modules.

• •

Do not apply pressurized air to any outlet or tubing connected to monitor.

• •

Do not break or bypass the patient isolation barrier when testing PC boards.

Electrostatic discharge through the PC boards may damage the components. Before handling PC boards, wear a static control wrist strap. Handle all PC boards by their non-conductive edges and use anti-static containers when transporting them. Do not clean the spirometry tubes with high pressure air O2 flushing while the spirometry tubes are connected to Patient Spirometry connector. High differential pressure may damage PVX unit pressure transducers.

Special components • Special components are used in these monitors that are vital to assure reliability and safety. GE Healthcare assumes no responsibility for damage, if replacement components not approved by GE Healthcare are used.

• A lithium battery on the CPU Board. Dispose of the faulty IC containing the battery according to local regulations.

Batteries The battery packages in the central unit, F-CPU and in the power supply unit of F-CU8 contain lead acid (Pb) which is hazardous to the environment and therefore needs to be disposed of carefully according to local regulations. To replace the batteries safely, please refer to the service instructions in this manual.

•

Do not short-circuit the battery terminals, this may produce a very high current, which will damage the battery.

•

Do not dispose of the battery into open flame, nor put the battery near fire, as it may explode.
