Question | Answer |
Tidal volume | Amt of air in a single inspiration or expiration |
Functional residual Capacity | Vol. of air that remains in the lungs @ the end of normal respiration |
Vital capacity | Max. amount of air expelled from lungs after max. inhalation |
Residual volume | Amount of air remaining in the lungs after max. expiration |
Total Lung Capacity | Max. volume of air in lungs after max. inspiration |
Forced Expiratory Volume | Volume that has been exhaled @ the end of the 1st second of forced expiration |
Forced vital capacity | Vol change of lungs between a full inspiration and a max. inspiration |
FEV1/FVC ratio | Proportion of a person's vital capacity that they are able to expire in 1st second of forced expiration |
Boyle's Law | Pressure is inversely proportional to the volume |
Pouiseuille's Law | States that the flow (Q) of fluid is related to a number of factors: the viscosity (n) of the fluid, the pressure gradient across the tubing (P), and the length (L) and diameter(r) of the tubing. |
Law of Laplace | P=2T/r |
Dalton's Law | Total pressure = sum of partial pressures |
Henry's Law | Solubility of a gas depends on partial pressure of gas in air & solubility coefficient of air in liquid |
Fick's Law | Amount of gas diffusing in unit time through the resistance of a barrier is inversely proportional to the thickness of barrier and is directly proportional to the thickness of the SA, diffusion constant and partial pressure diff. |
Graham's Law | The rate of diffusion is directly proportional to the solubility coefficient of the gas & inversely proportional to the square root of its molecular weight |
Minute ventilation | Vol. of gas inhaled or exhaled in a min |
VO2 max | Maximum amount of O2 that an individual can utilize during peak exercise |
Pulmonary ventilation | Vol. of air that moves in/out of lungs per minute |
Alveolar ventilation | Exchange of gas between alveoli and external environment |
Dead space | Space occupied by conducting airways (trachea, bronchi, bronchioles) |
Diffusion capacity | Used to see how well lungs are able to extract O2 from inhaled air |
