measurement and display of carbon dioxide (CO2) on a digitial or
analogue monitor. Maximum inspiratory and expiratory CO2
concentrations during a respiratory cycle are displayed.
graphic display of instantaneous CO2 concentration (FCO2)
versus time or expired volume during a respiratory cycle (CO2
waveform or capnogram)
waveforms which can be of two types: FCO2 can be plotted against
expired volume (SBTCO2 curve /volume capnogram/ CO2
expirogram) or against time (time capnogram) during a respiratory cycle.
pressure of CO2 in the alveoli.
pressure of CO2 in arterial blood.
pressure of CO2 at the end of expiration.
to end-tidal CO2 tension/pressure difference or gradient.
pressure of CO2 in mixed venous blood.
