Patient preparation for SpO2 monitoring
The following tips provide optimal SpO2 monitoring results but should never replace hospital-approved
practices or sensor manufacturer’s recommendations.
The accuracy of SpO2 monitoring depends largely on the strength and quality of the SpO2 signal.
If a finger is used as a monitoring site, remove any nail polish. Cut the finger nails of the patient, if
necessary.
The signal may vary due to the following conditions:
– Placement of a sensor that is too tight
– Patient experiences hypotension, severe vasoconstriction, severe anemia, or hypothermia
