End-tidal carbon dioxide (ETco2) monitoring provides valuable information about CO2 production and clearance (ventilation). Also called capnometry or capnography, this noninvasive technique provides a breath-by-breath analysis and a continuous recording of ventilatory status.
Why is end tidal CO2 important?
In critical care, End Tidal CO2 monitoring is used to assess adequacy of circulation to the lungs, which provides clues about circulation to the rest of the body. Low EtCO2 with other signs of shock indicates poor systemic perfusion, which can be caused by hypovolemia, sepsis or dysrhythmias.
