Abstract
In a system for measuring blood pressure and the like based on a sensed quantity representing the sum of pressure applied by a pressure cuff and a fluctuating component representative of the pulsatile pressure within the blood vessel method and apparatus for indicating blood pressure only if that pressure determined in a first preferred manner correlates substantially with a pressure determined in a secondary, different manner. More specifically, the sensed quantity is analyzed in a manner preferred for determining diastolic pressure and a manner preferred for determining systolic pressure, and the diastolic and systolic pressures or pressure ranges established by analyzing the sensed quantity in a secondary manner or manners. Examples of preferred and secondary techniques for diastolic and systolic pressure determinations are discussed.
