What does ETCO2 stand for?

• A. End-Tidal CO2
• B. End-Tidal Oxygen
• C. External Tracheal CO2
• D. Energy Transfer CO2

Answer: (A)

End-tidal CO2 is the concentration of carbon dioxide in the breath at the end of expiration, measured with capnography. This value reflects the CO2 level in alveolar gas and provides direct, real-time feedback on ventilation and airway patency. In anesthesia, monitoring ETCO2 helps confirm that ventilation is adequate, detect airway issues or disconnections, and assess how well CO2 is being eliminated. Normal adult values are typically about 35–45 mmHg, and the waveform shape gives additional clues about breathing pattern and pulmonary status. It’s not End-Tidal Oxygen, External Tracheal CO2, or Energy Transfer CO2.
