| conductance | 1. A measure of conductivity; the ratio of the current flowing through a conductor to the difference in potential between the ends of the conductor; the conductance of a circuit is the reciprocal of its resistance. 2. The ease with which a fluid or gas enters and flows through a conduit, air passage, or respiratory tract; the flow per unit pressure difference. (05 Mar 2000) |

| cystic fibrosis transmembrane conductance regulator | Gene believed to be defective in cystic fibrosis. Gene encodes a chloride channel, homologous to a family of proteins that actively transport small solutes in an ATP dependent manner (ABC transporters). The regulator protein is a protein which is embedded in the cell membrane and acts as a channel for certain ions to be transported into or out of the cell. The disease cystic fibrosis is caused by a defect in the gene for this protein. (09 Oct 1997) |
| airway | 1. Any part of the respiratory tract through which air passes during breathing. 2. In anaesthesia or resuscitation, a device for correcting obstruction to breathing, especially an oropharyngeal and nasopharyngeal airway, endotracheal airway, or tracheotomy tube. (05 Mar 2000) |
| airway obstruction | Any hindrance to the passage of air into and out of the lungs. (12 Dec 1998) |
| airway pattern | Chest radiographic appearance of thickened bronchial walls, bronchiectasis, bronchiolitis, or acinar consolidation. (05 Mar 2000) |
| airway resistance | The opposition of the tracheobronchial tree to air flow: the mouth-to-alveoli pressure difference divided by the air flow. (12 Dec 1998) |
| anatomical airway | The volume of the conducting airways from the external environment (at the nose and mouth) down to the level at which inspired gas exchanges oxygen and carbon dioxide with pulmonary capillary blood; formerly presumed to extend down to the beginning of alveolar epithelium in the respiratory bronchioles, but more recent evidence indicates that effective gas exchange extends some distance up the thicker-walled conducting airways because of rapid longitudinal mixing. Compare: alveolar dead space, physiologic dead space. Synonym: anatomical airway. (05 Mar 2000) |
| respiratory airway | That part of the airway where interchange of gases occurs; it includes respiratory bronchioles, alveolar ducts, sacs, and alveoli. (05 Mar 2000) |
| conducting airway | The airway from the nasal cavity to a terminal bronchiole. (05 Mar 2000) |
| continuous positive airway pressure | A technique of respiratory therapy, in either spontaneously breathing or mechanically ventilated patients, in which airway pressure is maintained above atmospheric pressure throughout the respiratory cycle by pressurization of the ventilatory circuit. (05 Mar 2000) |
| upper airway | The portion of the respiratory tract that extends from the nares or mouth to and including the larynx. (05 Mar 2000) |
| lower airway | The portion of the respiratory tract that extends from the subglottis to and including the terminal bronchioles. (05 Mar 2000) |
| airway conductance |
the reciprocal of airway resistance: the air flow divided by the mouth-to-alveoli pressure difference.
