End tidal CO 2 monitoring is represented as a number and a graph on a monitor. The number is called capnometry, which is the partial pressure of CO 2 detected at the end of exhalation, ranging between 35 - 45 mm Hg or 4.0 – 5.7 kPa. The waveform is called capnograph and shows how much CO 2 is present ...
