Description: Disposable adult anesthesia circuits play an important role in the medical care sector. These circuits act as mediators between the anesthesia machine and the patient’s airways. Their main task includes providing oxygen to the patient, removing CO2 from the body, and controlling temperature and humidity. In addition, these circuits provide additional capabilities including sampling, pressure control, flow and volume monitoring. Because effective breathing and precise control are important, disposable anesthesia circuits enhance the quality of patient care and are critical tools in medical settings.
