| alveolar air | The gas in the pulmonary alveoli, where O2-CO2 exchange with pulmonary capillary blood occurs. Synonym: alveolar air. (05 Mar 2000) |
|---|---|
| ambient air quality | The condition of the air in the surrounding environment. (05 Dec 1998) |
| blood-air barrier | The barrier between capillary blood and alveolar air comprising the alveolar epithelium and capillary endothelium with their adherent basement membranes and epithelial cell cytoplasm. Gaseous exchange occurs across this membrane. (12 Dec 1998) |
| vitiated air | Air containing a reduced percentage of oxygen. (05 Mar 2000) |
| reserve air | The extra volume of air that can be expired with maximum effort beyond the level reached at the end of a normal, quiet expiration. Common abbreviation is erv. (12 Dec 1998) |
| residual air | The volume of air remaining in the lungs at the end of a maximal expiration. Common abbreviation is rv. (12 Dec 1998) |
| minimal air | The volume of gas that remains in the lungs and cannot be expelled after they have been removed from the body, or after the chest has been opened. (05 Mar 2000) |
| combustion air | The air fed to a fire to provide oxygen for combustion of fuel. It may be preheated before injection into a furnace. (05 Dec 1998) |

| complementary air | The maximum volume of air that can be inspired after reaching the end of a normal, quiet expiration. It is the sum of the tidal volume and the inspiratory reserve volume. Common abbreviation is ic. (12 Dec 1998) |
| supplemental air | The extra volume of air that can be expired with maximum effort beyond the level reached at the end of a normal, quiet expiration. Common abbreviation is erv. (12 Dec 1998) |

| laminar air flow unit | An air-filtering system used at some transplant facilities to remove particulate matter and fungi from the air. (16 Dec 1997) |
| functional residual air | The volume of air remaining in the lungs at the end of a normal, quiet expiration. It is the sum of the residual volume and the expiratory reserve volume. Common abbreviation is frc. (12 Dec 1998) |
