All variables were manually recorded every 5 minutes. WebWhen CO2 diffuses out of the lungs into the exhaled air, a device called a capnometer measures the partial pressure or maximal concentration of CO2 at the end of exhalation and depicts it graphically as a capnogram. It provides information on ventilation, perfusion, and metabolism, which is important for airway management.
