Warnings

• Do not use in an explosive atmosphere or in the presence of flammable anesthetics or gasses.
• Do not use this device in an MR environment.
• This device is not defibrillation proof per IEC 60601-1.
• 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.
• Inspect the sensor application site at least every 4 hours to ensure correct sensor alignment and skin integrity. Patient sensitivity to the sensor may vary due to medical status or skin condition.
• Oximeter readings of this device may be affected by the use of an electrosurgical unit (ESU).
• To avoid patient injury, use only with Non-in-branded PureLight® pulse oximeter sensors. These sensors are manufactured to meet the accuracy specifications for Nonin Pulse Oximeters. Using other manufacturers’ sensors can result in improper pulse oximeter performance.
• To prevent improper performance and/or patient injury, verify compatibility of the monitor, sensor(s), and accessories before use.
• No modifications to this device are allowed as it may affect device performance.
• Do not use a damaged sensor. If the sensor is damaged in any way, discontinue use immediately and replace the sensor.
• As with all medical equipment, carefully route patient cabling to reduce the possibility of entanglement, strangulation, or injury to the patient.
• 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.
• The use of accessories, sensors, and cables other than those specified in the Parts and Accessories List may result in increased electromagnetic emission and/or decreased immunity of this device.
• This device must be able to measure the pulse properly to obtain an accurate SpO2 measurement. Verify that nothing is hindering the pulse measurement before relying on the SpO2 measurement.
• Operation of this device below the minimum amplitude of 0.3% modulation may cause inaccurate results.
• Discontinue use of adhesive tape strips if the patient exhibits an allergic reaction to the adhesive material.
• Avoid excessive pressure to the sensor application site as this may cause damage to the skin beneath the sensor.
• The device turns off after approximately 10 minutes when at critically low battery capacity.
• Before changing the batteries, make sure the device is off and the sensor is not applied to a digit.
• Portable RF communications equipment such as cell phones or radios (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the ME system, including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result.

Cautions

• Before use, carefully read the Instructions for Use provided with the sensors.
• When mounting the monitor to a mobile pole, mounting the monitor higher than 1.5 meters (5 feet) or mounting more than 2 kilograms (4.5 pounds) of equipment onto the pole may result in tipping, damage to the equipment, or injury.
• This device is not an apnea monitor.
• Verify that all visible indicators illuminate during the startup (initialization) sequence. If any indicator is not lit, do not use the device. Contact Nonin Technical Service for assistance.
• The presence of a defibrillator may interfere with the performance of this device.
• This device may not work on all patients. If you are unable to achieve stable readings, discontinue use.
• This device has motion tolerant software that minimizes the likelihood of motion artifact being misinterpreted as good pulse quality. In some circumstances, however, the device may still interpret motion as good pulse quality. Minimize patient motion as much as possible.
• Ear Clip and Reflectance sensors are not recommended for pediatric or neonatal use. The accuracy of these sensors has not been established for pediatric or neonatal use.
• Do not autoclave or immerse the device or sensors in liquid. Do not expose the device or components to excessive moisture or liquids.
• Do not use caustic or abrasive cleaning agents on the device or the sensors.
• The oximeter sensor might not work on cold extremities due to reduced circulation. Warm or rub the finger to increase circulation, or reposition the sensor.
• Always replace the batteries with fully charged batteries. Do not use fully charged and partially charged batteries at the same time as this may cause the batteries to leak.
• Use only Nonin-specified battery types with this device.
• Do not remove any covers other than the battery cover when replacing batteries. There are no user-serviceable parts inside other than the replaceable batteries.
• Follow local, state and national governing ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries.
• Batteries may leak or explode if used or disposed of improperly.
• Remove the batteries if the device will be stored for more than 1 month.
• This equipment complies with IEC 60601-1-2 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.
