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.
CAUTION • Injected dyes such as methylene blue, or intravascular dyshemoglobins such as methemoglobin and

electromagnetic interference can give unexpected intermittent readings when the sensor is not attached
to a patient. Especially bandage-type sensor designs are sensitive to minimal sensor movement that
might occur when the sensor is dangling.
