Abstract
A method for measuring a patient's blood pressure involves using a patient-applied cuff operably connected to an electronically controlled blood pressure monitor that includes a pump. The method includes controlling pressure in the cuff by inflating the cuff to a suprasystolic pressure, and step-wise deflating of the cuff to acquire blood-pressure data from the patient. The improvement includes using pulse-width modulation data to enhance control of cuff pressure.
