End-tidal CO2 monitoring

End-tidal CO2 (EtCO2) monitoring measures the amount of carbon dioxide (CO2) in a person’s breath at the end of exhalation. It provides real-time information about how well a person is ventilating, or exchanging gases in their lungs. This is useful in medical settings for patient care, anesthesia, and emergency situations, helping clinicians assess breathing effectiveness, detect respiratory problems early, and ensure proper ventilation during anesthesia or resuscitation. The device typically uses a sensor attached to a breathing circuit or mask to analyze the CO2 levels continuously.
