Method and device for calculating blood pressure based on arterial blood flow and arterial lumen measurements

摘要

The system for calculating blood pressure may include a sensor system and a control system. The control system may be capable of controlling at least two measurements by controlling one or more sensors of the sensor system, wherein at least two measurements are two or more different measurements of the subject's limb. Includes at least one measurement taken at each altitude. In some examples, the control system determines the blood flow difference based on at least two measurements, determines the hydrostatic pressure difference based on two or more different measurement altitudes of the at least two measurements, and the blood flow It may be possible to estimate the blood pressure based on one or more values of the hydrostatic pressure difference and the blood flow difference.
