Precautions For Use - Nonin Avant 4100 Operator's Manual

Precautions for Use

Contraindications
Do not use any part of this system in an MRI environment.
Explosion Hazard: Do not use this system in an explosive atmosphere or in the presence of
flammable anesthetics or gases.
Warnings
This system is intended only as an adjunct in patient assessment. It must be used in conjunc-
tion with other methods of assessing clinical signs and symptoms.
Oximeter readings may be affected by the use of an electrosurgical unit (ESU).
Use only NONIN-manufactured PureLight™ sensors. These sensors are manufactured to
meet the accuracy specifications for NONIN pulse oximeters. Using other manufacturers' sen-
sors can result in improper pulse oximeter performance.
Do not use a damaged sensor.
Do not use in or around water or any other liquid when the AC power adapter is used.
Use this pulse oximetry system with 300PS-XX AC power adapters, where XX represents the
power supply designation.
As with all medical equipment, carefully route cables and connections to reduce the possibility
of entanglement or strangulation.
All parts and accessories connected to the serial port of this system must be certified according
to IEC Standard EN 60950 or UL 1950 for data-processing equipment.
To avoid the risk of confusing or misinterpreting patient data, verify that the Model 4100 wrist-
worn patient module is paired with the correct display unit.
This pulse oximetry system is designed to determine the percentage of arterial oxygen satu-
ration of functional hemoglobin. Significant levels of dysfunctional hemoglobin, such as
methemoglobin, might affect the accuracy of the measurement.
The battery pack must be installed at all times while the device is operating—even when
operating on AC power. If it is necessary to operate the device without
batteries, audible alarms and memory functions may not be available. DO NOT use the
device without batteries when patient safety relies upon audible alarms.
Use the Avant 4000 system only within its designated range (approximately 30 feet—spherical
radius—from patient module to display). Moving outside this range may cause missing, lost,
and/or inaccurate data.
Loss of monitoring can result if any objects hinder the pulse measurement. Ensure that no
blood flow restrictors (e.g., blood pressure cuff) hinder pulse measurements.
This system may be interfered with by other equipment, even if that equipment complies
with CISPR emission requirements.
This device should not be used adjacent to or stacked with other equipment. If adjacent or
stacked use is necessary, the device should be observed carefully to verify normal operation.
In compliance with the European Directive on Waste Electrical and Electronic Equipment
(WEEE) 2002/96/EC, do not dispose of this product as unsorted municipal waste. This
device contains WEEE materials; please contact your distributor regarding take-back or
recycling of the device. If you are unsure how to reach your distributor, please call Nonin
for your distributor's contact information.
The use of accessories, sensors, and cables other than those listed in this manual may result
in increased emission and/or decreased immunity of this device.
