Abstract
A method for detecting motion artifacts in data obtained from a blood pressure monitoring transducer is provided which prevents erroneous data related to such artifacts from interfering with the accuracy of the blood pressure measurement by way of continuously monitoring the pressure control source which maintains the transducer hold down pressure, and temporarily delaying data acquisition in the event the hold down pressure changes in excess of a predetermined limit.
