Abstract: An aspect of the disclosure pertains to a blood pressure measurement device and methods of obtaining pulse information from a blood pressure measurement. An inflatable bladder defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage, where the inflatable bladder is inflated to a pressure greater than a maximum amplitude pressure from oscillometric data in a pressure profile. The inflatable bladder may be deflated and then re-inflated to a target pressure and held at the target pressure to generate pulse information, or the inflatable bladder may be deflated to the target pressure and held at the target pressure to generate the pulse information.

Abstract: An aspect of the disclosure pertains to a blood pressure measurement device and methods of controlling an inflation rate in a blood pressure measurement. An inflatable bladder of the blood pressure measurement device defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage. A pressure sensor of the blood pressure measurement device is configured to obtain blood pressure measurements, and a pump of the blood pressure measurement device is configured to inflate the inflatable bladder and control an inflation rate by controlling at least one of a duty cycle, a voltage, or a drive frequency.
