Abstract
The present invention is a method and apparatus for calculating blood pressure of an artery having a pulse. The method includes applying a varying pressure to the artery. Pressure waveforms are sensed to produce pressure waveform data. Waveform parameters are derived from the sensed pressure waveform data. Blood pressure is then determined using the derived parameters. The apparatus is a blood pressure monitoring device which includes pressure means for applying a varying pressure to the artery so that the artery exhibits pressure data, sensing means for sensing the pressure data, signal producing means connected to the sensing means for producing output signals corresponding to the sensed pressure data and processing means for receiving the output signals from the signal producing means, for deriving a plurality of parameters using sensed pressures and for determining a blood pressure value using the derived parameters.
