The Insight eNO System has five main components – a compact desktop monitor, an accurate eNO sensor, disposable breath tubes, smart patient cards, and a dedicated printer. In addition, it comes with quality control kits and carbon dioxide filters. The Insight eNO System’s biosensor is a novel, porous matrix embedded with a protein that selectively binds to nitric oxide. When a patient exhales into the device, nitric oxide in the patient’s breath sample binds with a highly selective heme-protein inside the matrix. An optical measurement of this binding gives a highly accurate nitric oxide measurement in less than a minute.
