Note: Before use, carefully read this manual, accessory Instructions for Use, and all precautionary information and specifications.
Safety Information This section contains important safety information related to general use of the Nellcor™ Bedside SpO2 Patient Monitoring System. Other important safety information appears throughout the manual. The Nellcor™ Bedside SpO2 Patient Monitoring System will be referred to as the “monitoring system” throughout this manual.
1.2.1 Safety Symbols
Table 1-1. Safety Symbol Definitions Symbol
Definition WARNING Alerts users to potential serious outcomes (death, injury, or adverse events) to the patient, user, or environment. Caution Identifies conditions or practices that could result in damage to the equipment or other property.

1.2.2 Warnings
1-2
WARNING: Explosion hazard - Do not use the monitoring system in the presence of flammable anesthetics. WARNING: Explosion hazard - Do not use the monitoring system with other manufacturer's batteries. Do not use different types or models of batteries such as dry batteries, nickel-metal hydride batteries, or Lithium-ion batteries together. WARNING: Do not use any monitoring system or pulse oximetry cables, sensors, or connectors that appear damaged. WARNING: As with all medical equipment, carefully route patient cabling to reduce the possibility of patient entanglement or strangulation. WARNING: Do not touch signal input, signal output or other connectors, and the patient simultaneously. 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. WARNING: To ensure patient safety, do not place the monitoring system in any location where it might drop on the patient.
Operator’s Manual
Safety Information
Operator’s Manual
WARNING: The LCD panel contains toxic chemicals. Do not touch broken LCD panels. Physical contact with a broken LCD panel can result in transmission or ingestion of toxic substances. 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: The monitoring system is intended only as an adjunct in patient assessment. It must be used in conjunction with clinical signs and symptoms. WARNING: The measured values of the monitoring system can be affected by patient conditions, excessive patient movement, sensors, environmental conditions, and nearby electromagnetic external conditions. WARNING: When the monitoring system is set to Standard Mode, it is intended for use in a hospital or hospital-type environment by trained medical personnel. WARNING: Failure to cover the pulse oximetry sensor site with opaque material in high ambient light conditions may result in inaccurate measurements. Pulse oximetry readings and pulse signals can be affected by certain environmental conditions, pulse oximetry sensor application errors, and certain patient conditions. Refer to the appropriate sections of this manual for specific safety information. 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.
1-3
Introduction
WARNING: The monitoring system may retain trend data from multiple patients if transferred from one patient to another. WARNING: Any connections between this monitoring system and other devices must comply with applicable medical systems safety standards such as IEC 60601-1. Failure to do so could result in unsafe leakage current and grounding conditions. WARNING: Do not silence or decrease the volume of the audible alarm if patient safety could be compromised. WARNING: Do not preset different alarm limits for the same or similar equipment within a single area.
1.2.3 Cautions
1-4
Caution: The monitoring system may not operate properly if it is operated or stored at conditions outside the ranges stated in this manual, or if it is subjected to excessive shock or dropping. Caution: Do not spray, pour, or spill any liquid on the monitoring system, its accessories, connectors, switches, or openings in the chassis, since this may cause damage to the monitoring system. Never place fluids on the monitoring system. If fluid spills on the monitoring system, remove batteries, wipe dry immediately, and have it serviced to ensure no hazard exists. Caution: Accessory equipment connected to the monitoring system's data interface must be certified according to IEC 60950-1 for data-processing equipment. All combinations of equipment must be in compliance with IEC 60601-1:2005 Requirements for Medical Electrical Systems. Anyone who connects additional equipment to the signal input or signal output port configures a medical system and is therefore responsible
Operator’s Manual
Safety Information
for ensuring the system complies with the requirements of IEC 60601-1:2005 and IEC 60601-1-2:2007.
Caution: When connecting the monitoring system to any instrument, verify proper operation before clinical use. Both the monitoring system and the instrument connected to it must be connected to a grounded outlet. Caution: For best product performance and measurement accuracy, use only accessories supplied or recommended by Covidien. Use accessories according to the manufacturer's directions for use and institutional standards. Use only accessories that have passed the recommended biocompatibility testing in compliance with ISO 10993-1. The use of accessories, sensors, and cables other than those specified may result in inaccurate readings of the monitoring system and increased emission and/or decreased electromagnetic immunity of the monitoring system.
Operator’s Manual
Caution: Where the integrity of the external protective conductor in the installation or its arrangement is in doubt, the monitoring system operates from its battery. Caution: This monitoring system generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to other devices in the vicinity. Caution: Inspect the monitoring system and all accessories before use to ensure there are no signs of physical damage or improper function. Do not use if damaged. Caution: Follow local government ordinances and recycling instructions regarding disposal or recycling of device components, including its accessories.
