Capnometer

A capnometer is a medical device that measures the amount of carbon dioxide (CO₂) in a person's breath in real-time. It helps healthcare providers monitor ventilation and identify how effectively a person is breathing. During exhalation, the device analyzes the CO₂ levels, providing information about respiratory status, ventilation efficiency, and metabolic activity. Capnometry is especially useful during anesthesia, emergency care, or in critical patients to ensure proper breathing and to detect issues such as airway obstructions or respiratory failure quickly and accurately.
