Abstract
The gas exchange properties of the lung have long been known to theoretically support the non-invasive measurement of cardiac output and lung volume [1]. Methods based on carbon dioxide (CO2) elimination kinetics are among the first and most extensively studied [2]. From a clinical perspective, they are also the most attractive not only because of the particular physiologic and physical-biochemical characteristics of CO2, but also because of its universal availability. Furthermore, CO2-based methods are perfectly adaptable to clinical simplified measurement devices and modern intensive care unit (ICU) equipment such as mechanical ventilators or anesthesia machines. In this chapter, we will review characteristic features of CO2 kinetics and its measurement and present a novel capnodynamic method for the continuous and non-invasive measurement of end-expiratory lung volume and effective pulmonary blood flow.
