Methods for measuring blood pressure with automatic compensations

摘要

Disclosed is a method for measuring an arterial blood pressure of a subject comprising detecting a pulse-wave-related signal of the subject; extracting a feature from the signals; determining a factor that can affect the arterial blood pressure of the subject; and determining the arterial blood pressure based on the feature with an automatic compensation for the factors. The disclosed method reduces the error in measuring the blood pressure based on characteristics of the pulse-wave-related signals.
