What does the term "end-tidal carbon dioxide" monitoring indicate?

End-tidal carbon dioxide monitoring specifically measures the concentration of carbon dioxide (CO2) in the exhaled air at the end of expiration. This measurement provides valuable insights into a patient’s ventilation status. By analyzing the levels of CO2, healthcare professionals can assess the effectiveness of a patient’s breathing; higher levels can indicate hypoventilation while lower levels may suggest hyperventilation. This non-invasive monitoring technique is vital during procedures that involve sedation or anesthesia, allowing for the continual assessment of respiratory function and ensuring that ventilation remains adequate throughout the procedure.

The focus on CO2 levels in the exhaled air distinguishes this measure from others, such as blood oxygen levels, heart rate variability, or depth of anesthesia, which do not directly relate to CO2 exhalation. Thus, monitoring end-tidal CO2 is crucial in managing patient safety and optimizing respiratory care.
