UMD: Devices designed to permit the passage of gases (e.g., air, oxygen) to the lungs while preventing obstruction of the patient's upper airway. These airways include a variety of devices according to the technique used to facilitate the passage of gases, the intended application, and the expected time of use. In emergency and/or for short-time use, esophageal obturation with one- or two-lumen tubes and oropharyngeal artificial airways are typically used. For a few days of intubation, nasopharyngeal artificial airways are the most commonly used devices, while for longer periods (up to three weeks) endotracheal tubes are the preferred devices. When long-term mechanical ventilation is needed, tracheostomy tubes are used. Artificial airways are available in a variety of configurations from newborn to adult sizes.
