A capnograph measures carbon dioxide levels in inspired and expired air. This gives the anesthetist a good indicator of adequate respiration by estimating the partial pressure of the carbon dioxide in the bloodstream. As tissues produce and release carbon dioxide, it is carried to the lungs for elimination, and is then measured.
