Introduction[edit | edit source]
Capnography is a non-invasive measurement during inspiration and expiration of the partial pressure of CO2 from the airway. It provides physiologic information on ventilation, perfusion, and metabolism, which is important for airway management.
End tidal CO2 or EtCO2 is the maximum partial pressure of CO2 obtained at the end of exhalation. While a capnometer reports numeric values as a result, a capnograph adds a graphic display of a waveform, which represents expired CO2 as a function to either volume or time and the created waveform is referred to as capnogram.
Indications for Use[edit | edit source]
This technique allows insight into the alveolar ventilation, perfusion and metabolism of breathing. On top of the use of validity for the measured level of EtCO2, it gives us two main advantages. Firstly, The appropriate tracing/mark on a pulse oximeter guarantees that the recorded oxygen saturation provided is valid. Secondly, the evaluation of the provided waveform gives key information about latent, underlying physiologic conditions and the ongoing processes of diseases.[1]
Capnometry is a non-invasive monitoring technique. It allows quick and reliable insight into aspects like: ventilation, circulation, and metabolism. In diagnosis, monitoring, and prediction of outcome capnometry is an important tool, especially in the pre-hospital setting.[2]
The Future of Capnography[edit | edit source]
Capnography and the measurement of PETCO2 will be augmented in the future by relatively new measurement methodology. Including the study of oxygen kinetics as a future direction. [3]
