Projecting Blood Pressure Measurements With Limited Pressurization

Abstract:

Methods for estimating blood pressure values, and related blood pressure measurement systems, account for patient specific attributes. A method of estimating a blood pressure value of a patient includes receiving feature vector data corresponding to a pressure variation of a blood pressure cuff. The feature vector data is derived from physiological signals of the patient measured over the pressure variation of the blood pressure cuff. A first blood pressure value of the patient is estimated using a first algorithm that employs the feature vector data as input data.
