Does motion interfere with pulse oximeter accuracy?

Motion such as patient shivering, tremor, or other movements may affect the probe’s ability to detect an accurate signal. It may give an erroneous value if there is too much motion or prevent the device from obtaining a reading at all.  At present, there is no requirement by certifying bodies to test oximeter accuracy under controlled or standardized conditions of motion. Nonetheless, some manufacturers and labs do this testing routinely. The OpenOximetry.org Project is working to publish these data in our database while developing and advocating for standards for performance during motion.
