What is a primary monitor of capnography during anesthesia?

The primary monitor of capnography during anesthesia focuses on assessing end-tidal CO2 levels. Capnography is the measurement of the concentration of carbon dioxide (CO2) in respiratory gases, specifically at the end of exhalation. This measurement is critical for evaluating a patient's ventilation status during anesthesia.

End-tidal CO2 levels provide real-time feedback on the patient’s respiratory function and can indicate how well carbon dioxide is being eliminated from the body. Maintaining adequate levels of end-tidal CO2 is essential for ensuring effective ventilation and oxygenation. A rise in end-tidal CO2 may suggest hypoventilation or respiratory depression, while a significant drop may indicate hyperventilation or a disconnection in the breathing circuit.

Monitoring capnography is a vital part of anesthesia management because it allows for timely interventions to correct any breathing issues, thus enhancing patient safety and ensuring optimal anesthetic delivery.
