Arterial blood pressure

Abstract

The measurement of blood pressure (BP) is a key component of hemodynamic monitoring in various fields of medicine, including intensive care medicine, emergency medicine, and anesthesiology. Thus, it is crucial to understand the different technologies available for BP monitoring. This includes understanding the underlying measurement principles of invasive and noninvasive techniques and knowing their advantages and limitations in different clinical settings. In this chapter, we give a brief overview of the history of technologies for BP measurement, and we describe the available technologies for BP monitoring used in intensive care medicine with regard to their measurement principles, advantages, limitations, and clinical applicability.
