Abstract
Blood pressure measuring system and method in which the pressure transducer connected to an occluding cuff is isolated from the pressure source provided for inflating the cuff and a reference pressure is maintained in the transducer during a calibration cycle at the outset of a blood pressure measurement. During the calibration cycle, the level of the output signal provided by the transducer is adjusted until a reference level is reached, and thereafter the transducer is reconnected to the pressure source for the blood pressure measurement.
