CO2 monitors are medical devices that measure the concentration of carbon dioxide (CO2) in a patient's exhaled air. They provide crucial data on respiratory status, ensuring effective breathing. Commonly used in critical care, anesthesia, and for patients with respiratory conditions, they consist of:

1. Sensor: Detects CO2 levels in the exhaled breath.
2. Display Screen: Shows real-time CO2 levels and respiratory health indicators.
3. Alarm System: Alerts healthcare providers if CO2 levels are outside safe ranges.
4. Control Panel: Allows adjustment of settings based on patient needs.

CO2 monitors are vital for assessing ventilation and detecting respiratory issues.
