| Question | Answer |
| AV | Anatomic dead space The volume of air that occupies a non-respiratory section |
| TV | Tidal volume 10% of total lung volume Volume of air during quite inspiration/expiration |
| IRV | Inspiratory reserve volume 50% of total lung volume Maximum volume of air during inspiration after tidal volume |
| ERV | Expiratory reserve volume 15% of total lung volume Maximum volume of air during expiration after tidal volume |
| RV | Reserve volume 25% of total lung volume Gas remaining in lungs after a max expiration |
| VC | Vital capacity 75% of total lung volume Changes in volume between max inspiration/expiration VC = IRV+TV+ERV |
| FRC | Functional residual capacity 40% of total lung volume Volume of air in lungs after a normal exhalation FRC = ERV+RV |
| TLC | Total lung capacity 100% of total lung volume Volume of air after max inspiration TLC =RV+VC / TLC =FRC+IC |
| IC | Inspiratory capacity 60% of total lung volume The amount of air that can be taken in after a normal tidal exhalation IC =TV+IRV |
| FEV | Forced expiratory volume Specific time of exhalation during 1st, 2nd, 3rd FVC |
| FVC | Amount of air forced after a max expiration and max inspiration |
| VE | Minute volume ventilation Amount of air expired after 1 minute VE =TV x respiratory rate |
| PEF | Peak expiratory flow Max air forced at the beginning of a maneuver |
