Pulse Oximeter Module
Choosing the Appropriate Pulse Oximerer Sensor
Use the measurements provided in the user instructions accompanying the sensor to determine which
size of sensor should be used. Sensor size recommendations are based on digit height (thickness).
!
► Use only NONIN manufactured PureLight
TM
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 avoid the risk of confusing or misinterpreting patient data, verify that the patient
module is paired with the correct Nox T3 device.
► This pulse oximetry system might misinterpret motion as good pulse quality.
Minimize finger motion or change the type of sensor being used.
Attaching the Pulse Oximeter Module and Sensor
1. Attach the sensor to the pulse oximeter module. Press firmly to make sure the sensor is
securely connected. The pulse oximeter is automatically activated when an oximeter sensor is
connected.
2. Secure the wristband to the patient’s wrist
3. Insert the selected digit (refer to the sizing recommendations in the user instructions
accompanying the sensor) into the sensor. The patient’s digit must reach the end of the
sensor.
4. Direct the cable along the patient’s finger/toe, parallel to the arm/leg
5. Verify proper operation:
- The connection status LED flashes green when a connection is established
- It flashes amber if no connection is established.
The wristband can either be reused or discarded after each use, as desired. It may be cut to length to
accommodate a variety of patient arm sizes.
!
► Proper sensor placement is critical for good performance. If the sensor is not
positioned properly, light may bypass the tissue and result in SpO
2
inaccuracies.
► Do not fasten the pulse oximeter too tightly around the patient’s wrist. Inaccurate
readings and patient discomfort could result.
►Do not use a damaged sensor. If the sensor is damaged in any way, discontinue use
immediately and replace the sensor.

Precautions for Use of the Pulse Oximeter
!
► Oximeter readings may be affected by the use of an electrosurgical unit (ESU)
► This pulse oximetry system is designed to determine the percentage of arterial oxygen
saturation of functional hemoglobin. Significant levels of dysfunctional hemoglobin,
such as methemoglobin, might affect the accuracy of the measurement.
►To prevent improper performance and/or patient injury, verify sensor and pulse
oximeter compatibility before use.
►A functional tester cannot be used to access the accuracy of a pulse oximeter monitor
or probe.
► Factors that may degrade pulse oximeter performance include the following
- excessive ambient light
- excessive motion
- electrosurgical interference
- arterial catheter, blood pressure cuffs, infusion lines, etc.
- moisture in the sensor
- improperly applied sensor
- carboxyhemoglobin
