ABSTRACT:
An oscillometric blood pressure measuring device (200) is disclosed for determining systolic, mean and diastolic blood pressures. The device (200) includes a cuff (202) adapted to be continuously deflated during a measuring cycle. Analog signals representative of pulsatile changes in cuff pressure are utilized to generate signals representative of pulse characteristics, including peak amplitude and pulse integral characteristics. Difference signals are then generated for the pulses, representative of the difference between peak amplitudes and pulse integrals, and a determination is made as to the systolic and diastolic blood pressure based on these difference signals and static cuff pressures.
