airway


 

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.
 

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

 
Wikipedia: airway

The airways are those parts of the respiratory system through which air flows, to get from the external environment to the alveoli.

The airway begins at the mouth or nose, and accesses the trachea via the pharynx. The trachea branches into the left and right main bronchi at the carina, situated at the level of the second thoracic vertebra. The bronchi branch into large bronchioles, one for each lobe of the lung. Within the lobes, the bronchi further subdivide some 20 times, ending in clusters of alveoli.

The epithelial surfaces of the airways contain cilia. Inhaled particles stick to mucus (secreted by goblet cells) which is continuously removed from the airways by these cilia. The airway epithelium 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 are present in the airways. These cells protect the airways from infection by engulfing inhaled particles and bacteria.

Certain conditions require tracheal intubation to secure the airway. Airway devices are used to assist intubation.
