Abstract

A method for monitoring pressure of blood in an artery may include contacting a non-invasive sensor of a pressure of blood monitoring device at an area above an artery of a finger, collecting with the sensor one or more pressure data readings, other than readings corresponding to an air pressure reading, from the area after the contacting and after a pressure is exerted at the area on the sensor; and analyzing with a computing device the one or more pressure data readings to generate at least one of a blood pressure reading and a heart pulse reading.
