Abstract

A system for calculating blood pressure may include a sensor system and a control system. The control system may be capable of controlling one or more sensors of the sensor system to take at least twomeasurements, the at least two measurements including at least one measurement taken at each of two or more different measurement elevations of a subject's limb. In some examples, the control systemmay be capable of determining a blood flow difference based on the at least two measurements, of determining a hydrostatic pressure difference based on the two or more different elevations of the at least two measurements and of estimating a blood pressure based on one or more values of blood flow, the hydrostatic pressure difference and the blood flow difference.

Description

[0001] priority [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 294,876, filed February 12, 2016, entitled "METHODS AND DEVICES FORCALCULATING BLOOD PRESSURE BASED ON MEASUREMENTS OF ARTERIAL BLOOD FLOW ANDARTERIAL LUMEN," and filed on June 17, 2016 Priority to U.S. Provisional Patent Application No. 15 / 186,228, entitled "METHODS AND DEVICES FOR CALCULATING BLOOD PRESSURE BASED ON MEASUREMENTSOF ARTERIAL BLOOD FLOW AND ARTERIAL LUMEN," filed on 11 May 2009, both of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to medical devices, including but not limited to personal medical devices such as wearable medical devices. Background technique [0004] Devices for measuring cardiovascular properties generally suffer from the problem that the measurement itself seriously interferes with the state of the subject, leading to erroneous results. For example, current cuff-based methods for o...
