  2. Respiratory quotient - Wikipedia

    en.wikipedia.org/wiki/Respiratory_quotient

    The respiratory quotient value indicates which macronutrients are being metabolized, as different energy pathways are used for fats, carbohydrates, and proteins. [1] If metabolism consists solely of lipids, the respiratory quotient is approximately 0.7, for proteins it is approximately 0.8, and for carbohydrates it is 1.0.

    Respiratory physiology is the biological function of metabolic gas exchange. The complementary category for the anatomical structure of respiratory systems is Category:Respiratory system. The complementary category for the anatomical structure of respiratory systems is Category:Respiratory system.

  4. FEV1/FVC ratio - Wikipedia

    en.wikipedia.org/wiki/FEV1/FVC_ratio

    In obstructive lung disease, the FEV1 is reduced due to an obstruction of air escaping from the lungs. Thus, the FEV1/FVC ratio will be reduced. [4] More specifically, according to the National Institute for Clinical Excellence, the diagnosis of COPD is made when the FEV 1 /FVC ratio is less than 0.7 or [8] the FEV 1 is less than 75% of predicted; [9] however, other authoritative bodies have ...

  5. Lung volumes and capacities - Wikipedia

    en.wikipedia.org/wiki/Lung_capacities

    Online calculators are available that can compute predicted lung volumes, and other spirometric parameters based on a patient's age, height, weight, and ethnic origin for many reference sources. British rower and three-time Olympic gold medalist Pete Reed is reported to hold the largest recorded lung capacity of 11.68 litres; [ 16 ] [ 17 ] [ 18 ...

    The distinction is the way in which each is measured. Respiratory Exchange Ratio is measured using indirect calorimetry, that is the amount of oxygen consumed and the amount of carbon dioxide produced. The respiratory quotient can be measured across a capillary bed of a particular organ or even a collection of cells in vitro.

    en.wikipedia.org/wiki/Indirect_calorimetry

    where RQ is the respiratory quotient (ratio of volume CO 2 produced to volume of O 2 consumed), is 21.13 kilojoules (5.05 kcal), the heat released per litre of oxygen by the oxidation of carbohydrate, and is 19.62 kilojoules (4.69 kcal), the value for fat. This gives the same result as the Weir formula at RQ = 1 (burning only carbohydrates ...

  9. Ventilation/perfusion ratio - Wikipedia

    en.wikipedia.org/wiki/Ventilation/perfusion_ratio

    In respiratory physiology, the ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the ventilation-perfusion coupling and thus the matching of two variables: V – ventilation – the air that reaches the alveoli; Q – perfusion – the blood that reaches the alveoli via the capillaries
