Carbon monoxide breath analyser

A carbon monoxide breath analyser is an electronic device used in clinical settings to measure the concentration of carbon monoxide in a patient's exhaled breath. It is employed to assess ventilatory function, such as lung diffusing capacity, or to monitor exhaled CO levels for purposes including newborn jaundice screening and smoking cessation support.

Devices in this category are regulated as medical instruments that analyze exhaled gases and may also measure ambient CO levels. They are typically supplied as standalone electronic units requiring calibration and proper use by trained healthcare personnel, with regulatory oversight focused on their measurement accuracy and safety in clinical environments.
