Summary

This chapter traces the history of the development of time and volumetric capnography. Rapidly responding, point-of-care CO2 analyzers were originally developed for medical use in response to needs expressed by clinicians of the day as part of an effort to understand a problem or so that therapy could be more optimally delivered. Innovations in mainstream gas sensors of the late 1980s resulted in smaller, more robust mainstream carbon dioxide (CO2) sensors, including pulsed thick film infrared sources, and increased its robustness by the use of a coaxial optical design. In the early 1990s, volumetric capnography sensors appeared, which combined mainstream flow and CO2 into an integrated airway adapter, as well as combining mainstream flow and sidestream CO2 sensors. Technological advances in sidestream systems continue, with newer source designs and novel configurations with removable sample cells, as well as mainstream designs that incorporate digital signal processors and miniaturized optics.
