Waveform capnography measures the partial pressure of carbon dioxide (CO2) detected at the end of exhalation. Known as end-tidal CO2, or EtCO2, this value provides important information about the health of patients—especially those in respiratory distress, cardiac arrest, or shock.

This measurement is displayed as a waveform that shows the respiratory rate and how much CO2 is present during each stage of respiration. Normal EtCO2 levels are 35 to 45 mm Hg, and the waveform generally has a rectangular shape. As the respiratory rate and tidal volume change, the waveform changes as well.
