Measuring SpO2

1
Select the correct patient category setting (adult/pediatric and neonatal), as this is used to optimize
the calculation of the SpO
2
During measurement, ensure that the application site:
has a pulsatile flow, ideally with a perfusion indicator value above 1.0.
has not changed in its thickness (for example, due to edema), causing an improper fit of the
sensor.
WARNING
Inspect the application site every two to three hours to ensure skin quality and correct optical
alignment. If the skin quality changes, move the sensor to another site. Change the application site
at least every four hours.
Injected dyes such as methylene blue, or intravascular dyshemoglobins such as methemoglobin
and carboxyhemoglobin may lead to inaccurate measurements.
Inaccurate measurements may result when the application site for the sensor is deeply pigmented
or deeply colored, for example, with nail polish, artificial nails, dye or pigmented cream.
Interference can be caused by:
High levels of ambient light (including IR warmers) or strobe lights or flashing lights (such as
fire alarm lamps). (Hint: cover application site with opaque material.)
Another SpO
performed on the same patient). Always cover both sensors with opaque material to reduce
cross-interference.
Electromagnetic interference, especially at perfusion indicator values below 1.0 and signal
quality indicator below medium.
Excessive patient movement and vibration.
