Capnography is used to monitor what aspect of anesthesia?

Explanation:
Capnography measures carbon dioxide in the exhaled gas and presents it as a real-time waveform, showing the end-tidal CO2 concentration. In anesthesia, this directly reflects ventilation status—how effectively CO2 is produced and eliminated by the lungs. The end-tidal CO2 value tells you if the patient is being ventilated adequately, helps confirm airway patency and correct tube placement, and alerts you to problems like hypoventilation, apnea, disconnection, or rebreathing. Oxygen saturation, blood pressure, and temperature are monitored by other devices, but capnography specifically provides immediate feedback on ventilation and CO2 elimination.
