It’s one of the occasional issues we hear about BP monitors and automated BP technology, ours included. And while it’s one of the reasons that we blog about the 10 Steps to Accurate Manual Blood Pressure Measurement and the 10 Factors That Can Affect Blood Pressure Readings, sometimes it takes more guidance to diagnose if a monitor is mis-reading. Comparing BP measurements manually taken by an observer to those from a monitor is a common way of examining the accuracy of a monitor. Clinical standards1 that determine a monitor's accuracy provide detailed methods for making these comparisons.
