ABSTRACT:
A non-invasive, non-intrusive, convenient and portable device for monitoring a user's arterial blood pressure is provided. The continuous blood pressure monitoring device includes a transducer mounted to detect arterial wall movement caused by blood flow through an artery of the user and means for measuring the output signals of the transducer and accurately converting these signals to systolic and diastolic blood pressure readings on a continuous basis. Calibration data is collected by periodically comparing transducer output signals and the simultaneous outputs of a separate diagnostically accurate blood pressure measuring device (such as a cuff sphygmomanometer), which is not coupled to the device during normal blood pressure monitoring. Blood pressure is computed from the measured transducer output signals and the calibration data.
