Capnography

  • Chapter
Pulmonary Function in Mechanically Ventilated Patients

Part of the book series: Update in Intensive Care and Emergency Medicine ((UICM,volume 13))

Abstract

Capnography is a technique for analyzing and visualizing CO2 concentration in the gas used in breathing. The measurement systems used give the digital value of CO2 concentration, expressed as a percentage or in mmHg, and a graphic representation in real time on an oscilloscope or monitor screen. CO2 concentration is usually plotted on the ordinate axis and time on the abscissa axis. This simple system is a sensitive indicator of metabolic changes and disturbances in tissue perfusion, and also reflect variations in pulmonary ventilation/perfusion relationship, as well as changes in lung mechanics in artificially ventilated patients.
