Abstract
A hand-held non-invasive blood pressure measurement device allows a varying pressure to be applied to an artery while 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 user is guided or prompted to apply the varying pressure through audible and visual feedback.
