Volume Capnography in the Intensive Care Unit: Physiological Principles, Measurements, and Calculations.

Summary of "Volume Capnography in the Intensive Care Unit: Physiological Principles, Measurements, and Calculations."

Volume capnography provides a non-invasive and continuous display of the fractional concentration or partial pressure of expired carbon dioxide versus exhaled volume. Derived measurements and calculations include the end-tidal, mean alveolar, and mixed expired PCO2, the volume of CO2 exhaled per breath and per minute, the airway, alveolar, and physiologic dead space volume, the physiologic dead space to tidal volume ratio, and expired minute ventilation, dead space ventilation, and alveolar ventilation. Thus, volume capnography provides a wealth of information about both respiratory and cardiovascular function, and it has many potential applications in critically ill patients. The effective use of volume capnography, however, requires a thorough understanding of its underlying physiological principles and the meaning and significance of derived measurements and calculations.
