Capnography Quiz

In a colormetric capnography device the litmus paper turns yellow when there is CO2 present in the exhaled air

Correct device placement must be confirmed utilizing all of the following: Chest rise and fall, Presence of lung sounds, Absence of epigastric sounds, ETCO2 colorimetric device and Pulse Oximetry.

When there is no circulation the colorimetric capnograph does not change color (inadequate CO2 present in the exhaled breath) since there is no gas exchange
