Figure 1

Evaluation of dead space volume (Vd) and end-tidal CO 2 concentration using volumetric capnography. The rectangle ABCD represents the same area as the CO2-volume-area under the capnographic curve (X) while BC represents a constant CO2 concentration that equals to end-tidal CO2. In this case, areas p and q are of the same size, and Vd according to Bohr represents the volume without CO2.
