ABSTRACT OF THE DISCLOSURE Improved method and apparatus for indicating blood pressure and the like in a varied-pressure cuff system wherein blood vessel pulsation signals are supplied to signal processing means for determining the blood pressure. The blood pressure pulsations are monitored to detect artifacts and the signal processing means inhibited if an artifact is detected. Upon detection of an artifact the pressure applied by the cuff is automatically adjusted to repeat the pressure at which the artifact is detected, thereby to seek artifact-free values. The pressure- repetition may be a discrete pressure or a limited pressure range. Further, a maximum number of limited-pressure repetitions may be established, after which the entire pressure range must be repeated.
