9.3 Description of measurements
Pulse oximetry measurements are displayed on the Pulse
Oximetry tile, the Pulse Oximetry screen and the Data and
Graphs screen. Measurements are updated every second.
Tap the Pulse Oximetry tile to open the Pulse Oximetry screen
and to open the Data and Graphs screen.
Tapping on the Pulse Oximetry screen provides a shortcut
to the pulse oximetry alarms and settings.
Caution
If any measurement seems questionable, check the patient's
vital signs by another method. Then check the pulse oximetry
accessories and Airvo 3 are set up, confi gured and working
correctly.
9.3.1 SpO

The Airvo 3 is calibrated to display functional oxygen saturation (SpO
measurements over a user selectable period (see Averaging Time in section 9.5 below). A long averaging period will generally produce
more stable values but the SpO

Stability of the SpO measurements displayed may provide a good

indication of a valid signal. Though stability is a relative term,
experience with the device and patient observations will help you
separate physiological eff ects from artifacts caused by a poorly-
placed sensor or excess patient motion.
Inconsistencies between SpO

blood gas analysis or clinical assessment may be caused by:
• poor signal quality,
• low perfusion,
• improperly-placed sensors or cables, and/or
• the patient's condition.
Connect sensor to Airvo 3
Connect the pulse oximeter USB connector cable to the USB port on the back of the
Airvo 3. Connect the pulse oximetry sensor cable into the USB connector cable. On fi rst
connection a selection popup screen will appear. Select the type of pulse oximter that
has been connected.
Warning
Carefully route cabling to reduce the possibility of patient entanglement or
strangulation.
Caution
The accuracy of the SpO₂ measurement may be aff ected if the total sensor cable length
(including extension cables) is greater than 3 meters.
Attach sensor to patient
Carefully select a pulse oximetry sensor based on the patient's age, weight and
intended sensor application site. More information can be found in the instructions
supplied with each sensor.
Warnings
Tissue damage may be caused by incorrect application of the sensor,
e.g. by wrapping the sensor too tightly. Follow the instructions supplied with the
sensor for correct application.
Use only compatible oximetry sensors and accessories for SpO
measurements. Verify compatibility before use to avoid incorrect operation of your
Airvo 3, inaccurate measurements and/or patient injury. See Appendix 3 for a list of
compatible accessories.
