1.2.5 Patient Monitoring and Safety

WARNING:

Always disconnect and remove the monitoring system and sensors during magnetic resonance

imaging (MRI) scanning. Attempting to use the monitoring system during an MRI procedure could

cause burns or adversely affect the MRI image or the monitoring system's accuracy.

WARNING:

Keep patients under close surveillance when monitoring. It is possible, although unlikely, that

radiated electromagnetic signals from sources external to the patient and the monitoring system

can cause inaccurate measurement readings.

WARNING:

As with all medical equipment, carefully route patient cabling to reduce the possibility of patient

entanglement or strangulation.

WARNING:

Do not lift or carry the monitoring system by the pulse oximetry sensor or pulse oximetry interface

cable. The cable may disconnect and cause the monitoring system to drop on a patient or cause

damage to monitoring system surfaces.

1.2.6 Monitoring System Readings

WARNING:

The monitoring system may remain attached to the patient during defibrillation or during use of

an electrosurgical unit; however, the monitoring system is not defibrillator-proof, and readings

may be inaccurate during defibrillation and shortly thereafter.

WARNING:

Check the patient's vital signs by alternate means should there be any doubt about the accuracy

of any measurement. Request a qualified service technician confirm the monitoring system is

functioning correctly.

WARNING:

For best product performance and measurement accuracy, use only accessories supplied or

recommended by Covidien. Use accessories according to their respective Instructions for Use.

Introduction

1-6 Service Manual

1.2.7 Sensors, Cables, and Other Accessories

WARNING:

Before use, carefully read the pulse oximetry sensor Instructions for Use, including all warnings,

cautions, and instructions.

WARNING:

Use only the Covidien-approved pulse oximetry sensors, interface cables, and accessories. Use of

other sensors, cables, and accessories can result in inaccurate readings and increased monitoring

system emissions.

WARNING:

Do not use any other cables to extend the length of the Covidien-approved interface cable.

Increasing the length will degrade signal quality and may lead to inaccurate measurements.

WARNING:

To prevent damage, avoid undue bending of the sensor cable.

WARNING:

The sensor disconnect error message and associated alarm indicate the pulse oximetry sensor is

either disconnected or has faulty wiring. Check the connection and, if necessary, replace the

sensor, the pulse oximetry cable, or both.

1.2.8 Electromagnetic Interference

WARNING:

Any radio frequency transmitting equipment or other nearby sources of electrical noise may result

in disruption of the monitoring system.

WARNING:

The monitoring system is designed for use in environments in which the signal can be obscured by

electromagnetic interference. During such interference, measurements may seem inappropriate

or the monitoring system may not seem to operate correctly.

WARNING:

Large equipment using a switching relay for its power on/off may affect monitoring system

operation. Do not operate the monitoring system in such environments.
