To help ensure successful monitoring of your patient’s SpO

:
• Apply the pulse oximeter sensor to a well-perfused site.
• Select a measurement site that has unrestricted blood flow.
• Follow all the instructions supplied with the pulse oximetry sensor to ensure the device is correctly applied.
The Pulse oximeter status bar displays the status of the pulse oximeter. Tap the Pulse oximeter tile to open the Pulse Oximetry screen and
view the status. Possible status messages and warnings are described below.
Message Cause/remedy
Low Signal Quality
Indicates poor signal quality (signal inadequacy) and low confidence in the pulse oximeter measurements
displayed. Measurements are drawn in gray on the pulse oximeter tile when signal quality is low.
Low Signal Quality may be caused by excess motion, low perfusion, a long/blocked light path,
or a damaged or incorrectly fitted sensor.
• Follow the sensor’s user instructions to check it is the correct type and that it has been correctly applied to
the patient.
• Reduce or eliminate motion at the monitoring site.
• Consider an adhesive sensor.
• Check that the sensor’s emitter and detector are properly aligned, particularly when using an adhesive
sensor.
• Consider a different measurement site.
• Check that blood flow to the measurement site is not restricted.
• See the pulse oximetry section for physiological conditions that may affect pulse oximetry measurement
accuracy and consider an alternative method if indicated.
• Remove excessive fingernail polish or artificial nails.
• Replace the sensor.
Patient Missing The pulse oximeter cannot detect a patient. Check that the sensor is properly fitted by following the user
instructions supplied with the sensor.
If pulse oximeter measurements do not correlate with clinical assessment and/or arterial blood gas measurements:
• check the pulse oximeter status, as described above,
• check the pulse oximeter sensor is fitted correctly, following the user instructions supplied with the sensor,
• review the pulse oximetry section for conditions that may affect pulse oximetry measurement accuracy and consider an alternative
method if indicated, and/or
• try a different measurement site.
If the Airvo 3 loses power and the battery is depleted, pulse oximetry functionality will be lost. It will be restored once power is restored to
Airvo 3.
A “Pulse Oximeter Sensor Off Patient” alarm will be raised if the pulse oximeter sensor cannot detect a patient signal. Either:
1. Tap the Alarm Reset button to acknowledge the alarm and continue without SpO
2
monitoring, or
2. Reposition the sensor to recover the patient signal.
SpO
2
monitoring will restart automatically when the patient signal is detected.
