Pulse oximetry measurements and status are shown as follows:
Pulse oximetry is
connected to the Airvo 3,
but the sensor is not
attached to a patient.

Warnings
Nonin:
The Nonin Xpod USB connector is designed to determine the percentage of arterial oxygen saturation of functional
haemoglobin. Factors that may degrade pulse oximetry performance or aff ect the accuracy of the measurement
include the following:
• Excessive ambient light
• Excessive motion
• Electrosurgical interference
• Elevated levels of dyshemoglobin
• Blood fl ow restrictors (arterial catheters, blood
pressure cuff s, infusion lines, etc.)
• Moisture in the sensor
• Improperly applied sensor
• Incorrect sensor type
• Poor pulse quality
Loss of monitoring can result if any objects hinder the pulse measurement. Ensure that no blood fl ow restrictors (e.g.,
blood pressure cuff ) hinder pulse measurements.
The oximeter sensor may not work on cold extremities due to reduced circulation. Warm or rub the fi nger to increase
circulation, or reposition the sensor.
Inaccurate readings can result due to residue (e.g. dried blood) in light path or degradation of optical characteristics of
sensor components. Refer to cleaning instructions supplied with the pulse oximetry accessories.
False high readings can result if SpO₂ is low due to dysfunctional hemoglobin (e.g. carboxyhemoglobin or
methemoglobin).
Read the instructions supplied with the pulse oximetry accessories for additional safety information (including any
potential risks or adverse eff ects from sensor materials), measurement site selection, detailed sensor setup, maximum
sensor application time at a single site before repositioning, cable lifetime, sensor lifetime, factors that can interfere
with measurement, troubleshooting and maintenance instructions.
Poor signal quality may
be causing inaccurate
measurements
(see section 7 for
troubleshooting).
