End-tidal carbon dioxide (ETCO2) monitoring is a crucial tool in assessing the adequacy of ventilation and the patient's respiratory status during treatment. This non-invasive method measures the concentration of carbon dioxide in exhaled air, specifically at the end of expiration, which reflects the patient's metabolic and respiratory function.

Monitoring ETCO2 provides valuable information regarding the efficiency of gas exchange in the lungs. For instance, an increase in ETCO2 levels can indicate hypoventilation or respiratory failure, while a decrease may signify hyperventilation or other issues affecting gas exchange. By assessing these levels, healthcare providers can make informed decisions about patient management, including the need for airway interventions or changes in treatment protocols.

Understanding ETCO2 is critical in various emergency situations, as it allows for real-time monitoring of a patient's condition, ensuring appropriate responses to changes in their respiratory function.
