Note. denoted a vascular information parameter which might be altered with age and the development of cardiovascular diseases. For the healthy subjects, it was set as 0.031 mm·Hg⁻¹ [9]. , . could be determined at the beginning of monitoring by calibration using an additional cuff-type BP monitor device (see Subsection 3.2). were the corresponding function coefficients. was the subscript, and for their calibration method, see Subsection 3.2.
