Representative examples of a volumetric capnogram for both patient groups. Volumetric capnogram of a post-cardiac surgery patient (a) and a patient with acute respiratory distress syndrome (b) with values of PACO2, PETCO2, PeCO2, and dead-space fraction (VD/VT). SII and SIII are the slopes of phases II and III, respectively, of the volumetric capnogram (see Additional file 1: Fig. S2). PaCO 2 partial pressure of carbon dioxide in arterial blood, PACO 2 partial pressure of carbon dioxide in alveolar air, PeCO 2 partial pressure of carbon dioxide in mixed expired air, PETCO 2 end-tidal partial pressure of carbon dioxide
