UMD: Measuring instruments designed for direct evaluation and display of the carbon dioxide content either in a patient's exhaled gas, in body cavities, and/or in body tissues. Capnometers are used to check the correct placement of endotracheal tubes, to assess the pulmonary function or the adequacy of perfusion during cardiopulmonary resuscitation, and in diagnostics and checking the status of critically ill patients; they can also detect ventilator failure.
