ON-DEMAND BLOOD PRESSURE MEASUREMENT DEVICES AND METHODS

原文（中国語）

Embodiments are directed to systems and methods for determining blood pressure (e.g., diastolic and systolic pressure) of a user. A pressure applied by a skin region of a user and an optical cardiac signal are simultaneously measured. The optical cardiac signal, which may correspond to a measured skin region blood volume, is analyzed to identify a series of pulse waves, which in some instances may be normalized. A series of values of a metric associated with the morphology of the pulse waves is determined. The metric values are associated with corresponding pressure values. The metric values and pressure values are used to determine diastolic pressure and systolic pressure.
