End tidal CO2 (EtCO2) monitor

End tidal CO2 (EtCO2) monitor
The photo shows a child being monitored with capnography: 29 is the end tidal CO2. The capnographic waveform appears in the screen adjacent to the number. The nasal prongs and the bladder that extends from the front of the mouth detect exhaled CO2.
