Abstract:
A method for determining blood pressure of an artery having a pulse, the method comprising:applying a pressure to the artery; sensing pressure produced by the artery to produce sensed pressure data representing a pressure waveform for at least one pulse; deriving a plurality of parameters related to waveform shape from the sensed pressure data including at least one of the following: (a) rise time of a selected portion of a waveform, (b) applied pressure corresponding to a starting point of a waveform, (c) applied pressure corresponding to an ending point of a waveform, (d) pressure of a waveform at a selected time, (e) a pressure corresponding to a selected point on a waveform, (f) a time value corresponding to a width of a selected portion of a waveform, (g) mean amplitude of a waveform, (h) mean of a curve generated from data taken from a plurality of waveforms; and determining a blood pressure value based upon the parameters.
