Clinical Aspects of Capnography

  • Ll. Blanch
Conference paper

Abstract

Capnography permits recognition of CO2 concentration changes in the patient’s airway during the respiratory cycle. The capnogram represents total CO2 eliminated by the lungs, given that no gas exchange occurs in the airways. Expired gas contains CO2 from three sequential compartments: phase I contains gas from apparatus and anatomic dead space, phase II represents increasing CO2 concentration resulting from progressive emptying of alveoli, and phase III represents essentially alveolar gas. The highest point is the end-tidal PCO2 [1–4].
