Lung volumes and capacities
| Term | Definition |
|---|---|
| Anatomic dead space volume (AD) | The volume of air that occupies the non-respiratory conducting airways |
| Expiratory reserve volume (ERV) | The volume of air that can be exhaled after a normal tidal exhalation. 15% of total lung volume |
| Forced expiratory volume (FEV) | Volume of air exhaled in a specified period of time: usually the 1st, 2nd, and 3rd second of a forced vital capacity maneuver |
| Forced vital capacity (FVC) | Volume of air expired from a forced maximal exhalation after a forced maximal inhalation |
| Functional residual capacity (FRC) | Volume of air in the lungs after a normal exhalation. FRC = ERV + RV. About 40% of total lung volume |
| Inspiratory capacity (IC) | Volume of air that can be inspired after a normal tidal exhalation. IC = TV + IRV. About 60% of total lung volume. |
| Inspiratory reserve volume (IRV) | Volume of air that can be inspired after a normal tidal inspiration. 50% of total lung volume |
| Minute volume ventilation (VE) | Volume of air expired in one minute. VE = TV x respiratory rate |
| Peak expiratory flow (PEF) | Max flow of air during the beginning of a forced maximal expiration |
| Residual volume (RV) | Volume of gas in the lungs after a maximal expiration. 25% of total lung volume |
| Tidal volume (TV) | Total volume inspired and expired w/ each breath during quiet breathing. 10% of total lung volume. |
| Total lung capacity (TLC) | Volume of air in the lungs after a maximal inspiration; sum of all lung volumes. TLC = RV + VC or TLC = FRC + IC |
| Vital capacity (VC) | Volume change that occurs between maximal inspiration and maximal expiration. VC = TV + IRV + ERV. 75% of total lung volume. |
