ETCO2 stands for which phrase?

• A. End-tidal Carbon Dioxide
• B. Exhaled Total Carbon Dioxide
• C. End-tidal Carbon Monoxide
• D. Exhaled Carbon Dioxide

Answer: (A)

ETCO2 refers to the amount of carbon dioxide at the end of an exhaled breath—the end-tidal part—measured by capnography. This measurement is used to assess ventilation and airway status, such as confirming proper airway placement and monitoring the effectiveness of chest compressions during CPR. The correct phrase is End-tidal Carbon Dioxide. The other options aren’t standard terms: Exhaled Total Carbon Dioxide isn’t a recognized way to describe this monitoring, End-tidal Carbon Monoxide would refer to CO, not CO2, and Exhaled Carbon Dioxide is too general and doesn’t specify the end-tidal measurement.
