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.

3. Shunt equation - Wikipedia

   en.wikipedia.org/wiki/Shunt_equation

   The Shunt equation (also known as the Berggren equation) quantifies the extent to which venous blood bypasses oxygenation in the capillaries of the lung.. “Shunt” and “dead space“ are terms used to describe conditions where either blood flow or ventilation do not interact with each other in the lung, as they should for efficient gas exchange to take place.

4. Alveolar gas equation - Wikipedia

   en.wikipedia.org/wiki/Alveolar_gas_equation

   The alveolar gas equation is the method for calculating partial pressure of alveolar oxygen (p A O 2).The equation is used in assessing if the lungs are properly transferring oxygen into the blood.

5. Dead space (physiology) - Wikipedia

   en.wikipedia.org/wiki/Dead_space_(physiology)

   Mechanical dead space or external dead space is volume in the passages of a breathing apparatus in which the breathing gas flows in both directions as the user breathes in and out, causing the last exhaled gas to be immediately inhaled on the next breath, increasing the necessary tidal volume and respiratory effort to get the same amount of ...

6. Indirect calorimetry - Wikipedia

   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 ...
