Instructions for Use

Onyx II Model 9550 Finger Pulse Oximeter
®
0123

Indications for Use

The NONIN® Onyx
measuring and displaying functional oxygen saturation of arterial hemoglobin (%SpO
or poorly perfused. It is intended for spot-checking of adult and pediatric patients on fingers (other than the thumb) between
0.3 - 1.0 inch (0.8 – 2.5 cm) thick.
Caution: Federal law (USA) restricts this device to sale by or on the order of a licensed practitioner.
Contraindications
• Do not use the device in an MRI environment, in an explosive atmosphere, or on infant or neonatal patients.
• This device is not defibrillation proof per IEC 60601-1:1990 clause 17h.
Warnings
• This device is intended only as an adjunct in patient assessment. It must be used in conjunction with other methods of
assessing clinical signs and symptoms.
• The device must be able to measure the pulse properly to obtain an accurate SpO
hindering the pulse measurement before relying on the SpO
• Operation of this device below the minimum amplitude of 0.3% modulation may cause inaccurate results.
• General operation of the device may be affected by the use of an electrosurgical unit (ESU).
• The use of accessories other than those specified in these instructions may result in increased electromagnetic emission
and/or decreased immunity of this device.
• 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.
Cautions
• This device is designed to determine the percentage of arterial oxygen saturation of functional hemoglobin. Significant
levels of dysfunctional hemoglobin may affect measurement accuracy.
• This device has no audible alarms and is intended only for spot-checking.
• Inspect the sensor application site at least every 6 to 8 hours to ensure correct sensor alignment and skin integrity. Patient
sensitivity to sensors may vary due to medical status or skin condition.
• Fluctuating or very bright light, moisture, blood pressure cuffs, infusion lines, venous pulsations, insufficient pulse signals,
anemia, arterial catheters, nail polish, and/or artificial nails may degrade the device's performance.
• The device may not work when circulation is reduced. Warm or rub the finger, or re-position the device.
• This device's display will go blank after 30 seconds of no readings or poor readings.
• In some circumstances, the device may interpret motion as good pulse quality. Minimize patient motion as much as
possible.
• Cardiogreen and other intravascular dyes may affect the accuracy of the SpO
• Do not autoclave or immerse this device in liquid or use caustic or abrasive cleaning agents.
• A flexible circuit connects the two halves. Do not twist or pull the flexible circuit or overextend the device's spring.
• Do not hang the lanyard from the device's flexible circuit/strain relief.
• A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor or sensor.
• This equipment complies with IEC 60601-1-2:2001 for electromagnetic compatibility for medical electrical equipment and/
or systems. This standard is designed to provide reasonable protection against harmful interference in a typical medical
installation. However, because of the proliferation of radio-frequency transmitting equipment and other sources of
electrical noise in healthcare and other environments, it is possible that high levels of such interference due to close
proximity or strength of a source might disrupt the performance of this device. Medical electrical equipment needs special
precautions regarding EMC, and all equipment must be installed and put into service according to the EMC information
specified in this manual.
• Portable and mobile RF communications equipment can affect medical electrical equipment.
• Batteries may leak or explode if used or disposed of improperly. Remove batteries if the device will be stored for more
than 30 days. Do not use different types of batteries at the same time. Do not mix fully charged and partially charged
batteries at the same time. These actions may cause the batteries to leak.
• Follow local, state and national governing ordinances and recycling instructions regarding disposal or recycling of the
device and device components, including batteries.
• 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.
