Abstract
A pulse oximetry sensor adapted to emit light from an emitter proximate to a patient's tissue and detect a portion of the emitted light on a detector proximate to the tissue. The pulse oximetry system is adapted to acquire position data for the emitter and for the detector with one or more position indicators. The pulse oximetry system is adapted to process the position data to obtain a change in position of the emitter and the detector; and to process pulse oximetry measurements using the change in position to obtain a motion-corrected pulse oximetry data.
