Abstract
An apparatus for producing information indicative of the mean blood pressure of a living creature through indirect measurement comprising an inflatable cuff, a pump connected to the cuff, a deflating valve connected to the cuff, measuring apparatus connected to the cuff adapted to measure cuff pressure and pressure oscillations occurring in the cuff caused by the heartbeat of the living creature and control apparatus connected to the pressure measuring apparatus, pump and deflating valve. Deflation of the cuff occurs in pressure increments, with processing being done at each given decrement to evaluate plural successive pulsations for purposes of artifact rejection and identification of a true pulsation.
