Abstract

Cuffless blood pressure (BP) measurement is an all-inclusive term for a method that aims to measure BP without using a cuff. In our previous article, we reported the development of a simple cuffless technique based on the haemodynamic expression, using only pulse rate (PR) and modified normalized pulse volume (mNPV) that can be measured using only a smartphone. The stressor used in our previous article was the cardiac-dominant pattern (mental arithmetic); however, here we have experimented with another stressor, namely, a vascular-dominant pattern in a cold pressor test, to verify this theory in 7 healthy young males and 6 healthy young females (N = 22). As a result, the mean arterial pressure accuracy was improved (r = 0.727) compared with that achieved in the previous study.
