CAUTION
• Injected dyes such as methylene blue, or intravascular dyshemoglobins such as methemoglobin and
carboxyhemoglobin may lead to inaccurate measurements.
• Interference can be caused by:
– High levels of ambient light or strobe lights or flashing lights (such as fire alarm lamps). (Hint:
cover application site with opaque material.)
– Electromagnetic interference.
– Excessive patient movement and vibration.
