Abstract:
An automated sphygmomanometer apparatus, comprising:an inflatable and deflatable pressure cuff; an inflating apparatus coupled to said cuff so as to selectively apply a medium under pressure to said cuff for inflating and pressurizing said cuff; a cuff pressure sensor coupled to said cuff so as to sense cuff pressure including any blood pressure oscillations therein; a deflating apparatus coupled to said cuff so as to selectively relieve pressure from said cuff; and a programmed control device responsive to cuff pressure determination of said cuff pressure sensor, said control device programmed to control said inflating apparatus to inflate said cuff and said deflating apparatus to deflate said cuff during respective blood pressure determinations of a patient at predetermined intervals and to store oscillometric envelope data representing points of an oscillometric envelope defined by measured blood pressure oscillations, said control device further programmed to, to check the signal quality of said oscillometric envelope data, calculate the patient's blood pressure from said oscillometric envelope data if the quality of the oscillometric envelope data is good, and to selectively display the calculated blood pressure in accordance with the signal quality of said oscillometric envelope data.
