Abstract
A sensor may be adapted to reduce motion artifacts by mitigating the effects of the tissue moving within the sensor. A sensor is provided with an elastomeric sensor body adapted to accommodate patient motion. Further, a sensor is provided in which the sensor cable is arranged to mitigate its pressure on a patient'"'"'s tissue.
