End-tidal CO2 monitoring is a non-invasive way to monitor a patients carbon dioxide levels. The CO2 waveforms can help healthcare providers determine a possible diagnosis and come up with a treatment plan. For this technology to be useful the critical care nurse must have a clear understanding of the normal capnography waveform and what the alterations in this waveform represent.
Capnography measures ventilation through a metric known as end-tidal carbon dioxide EtCO2. EtCO2 is a measurement of the partial pressure of CO2 in gas expired at the end of exhalation when exhaled gas will most closely resemble the alveolar CO2 concentration. Author Jonathan L Benumof.

Both end-tidal CO2 monitors and pulse oximetry devices work closely together to help monitor the respiratory status of a patient. For instance a low-cardiac-output state generates a low end-tidal CO 2 because there is simply not enough flow across the pulmonary circulation.
