| Question | Answer |
| TV [ Tidal Volume ] | air exhaled = 500mL |
| ERV [ Expiratory reserve Volume ] | Largest additional volume of air that one can forcibly exhale after expiring tidal air = 1L -> 1.2L |
| IRV [ Inspiratory Reserve Volume ] | amount of air that can be forcibly inspired over and above typical inspiration = 3.3L |
| RV [ Residual Volume ] | amount of air you cannot forcibly expire = 1.2L |
| MV [ Minimal Volume ] | remains in lung tissue = 40% of RV |
| VC [ Vital Capacity ] | IRV + TV + ERV = VC |
| IC [ Inspiratory Capacity ] | IC = TV + IRV maximum amount of air a person can inspire after typical a typical expiration |
| FRC [ Functional Residual Capacity ] | FRC= ERV + RV amount of air left in the lungs at the end of a typical expiration without contracting expiratory muscles = 2.2L -> 2.4L |
| TLC [ Total Lung Capacity ] | total air a lung can hold = sum of all 4 lung volumes |
| AVV [ Alveolar Ventilation Volume ] | volume of inspired air that actually reaches the alveoli AVV = TV - Dead Space Volume |
| TMV [ Total Minute Volume ] | volume moved per minute = 500mL / cycle x 12 Breathes = 6L |
| FEV Test [ Forced Expiratory Volume Test] | determine the presence of obstruction by measuring the volume of air expired per second during forced expiration. |
| Boyles Law | The volume of a gas varies inversely with its pressure at a constant temperature [ P1V1 = P2V2] / PV = k |
| Dalton's Law - Partial Pressures | the partial pressure of a gas in a mixture of gases is directly related to the concentration of that gas in the mixture and to the total pressure of the mixture |
| Bohr Effect | Increase in Carbon Dioxide levels in blood will decrease blood Ph ( more acidic) = decreases the affinity of hemoglobin for oxygen |
| Haldane Effect | Deoxygenation of the blood ( makes it more basic ) increased its ability to carry carbon dioxide |
| Spirometer | Tool used to measure volume of air exchanged in breathing. |
| Spirogram | Graphic recording of change in pulmonary volumes observed during breathing |
