Volume capnography is a promising
non-invasive, inexpensive, breath by breath measurement that has the
potential to become an indispensable bedside monitoring tool that can
guide the therapeutic process of mechanically ventilated critically ill
patients. The better understanding of the pathophysiology of the acutely
injured lung on the one hand and the increasing knowledge about the
kinetics of CO2-exchange on the other has created a growing
interest in this technology. Volume capnography provides information
about the changes in the lung’s condition and might therefore allow for
improved monitoring of complex ventilatory interventions such as lung
recruitment and PEEP titration. In addition, the bedside assessment of VD
helps to identify patients at risk with uneven modes of ventilation and
to evaluate their response to different ventilatory strategies. Further
studies will help define the true role of volumetric capnography in
clinical decision making.1
