airway


(DOD, NATO) A control area or portion thereof established in the form of a corridor marked with radio navigational aids.

A control area, or a portion thereof, established in the form of a corridor (ICAO). An airway is equipped with radio navigation aids. It is a path through navigable airspace designated by the appropriate authority within which air traffic services are provided.

1. the passage by which air enters and leaves the lungs.
2. a mechanical device used for securing unobstructed respiration during general anesthesia or other occasions in which the patient is not ventilating or exchanging gases properly. Includes an endotracheal tube and a tracheostomy tube.

  • artificial a. — endotracheal or tracheostomy tubes.
  • a. obstruction — in the unanesthetized animal is usually caused by vomitus or laryngeal spasm due to foreign material in the larynx. In the nonintubated anesthetized animal, it is caused by caudal displacement of the tongue and epiglottis, accumulation of mucus, saliva and blood in the pharynx or laryngeal spasm resulting from that accumulation. In the intubated animal, faulty placement or functioning of the endotracheal tube or kinking of it can cause obstruction of the airway. The signs of obstruction are deep, asphyxial respirations, struggling and great agitation in the conscious animal. Deeply anesthetized animals simply show a decline in respiratory efficiency.
  • a. reflexes — aid in the removal of secretions and foreign material. See also cough, sneeze.
  • a. resistance — the resistance to airflow through the respiratory tree and any addition to the airway, such as the endotracheal tube and connectors in a closed circuit anesthetic machine.

n

1. a clear passageway for air into and out of the lungs. 2. a device for securing unobstructed respiration during general anesthesia or in states of unconsciousness.

The pulmonary airway comprises those parts of the respiratory system through which air flows, conceptually beginning (on inhalation from the external environment) at the nose and mouth, and terminating in the alveoli. It is generally used synonymously with respiratory tract, to avoid sounding overly scientific.

From the mouth or nose, inhaled air passes through the pharynx into the trachea, where it separates into the left and right main bronchi at the carina, situated at the level of the second thoracic vertebra. The main bronchi then branch into large bronchioles, one for each lobe of the lung. Within the lobes, the bronchioles further subdivide some twenty times, ending in clusters of alveoli.

The epithelial surfaces of the airway contain cilia. Inhaled particles adhere to mucus secreted by goblet cells, which is continuously driven outwards by the cilia. The epithelium of the airway also secretes a watery fluid upon which the mucus can ride freely. The production of this fluid is impaired by the disease cystic fibrosis. Macrophages in the airways help promote prophylaxis and prevent infection and contamination, by engulfing bacteria and other inhaled particles.

Certain conditions require tracheal intubation (insertion of a tube) to secure the patency (openness) of the airway. Airway devices are used to assist in tracheal intubation.
