  2. Fraction of inspired oxygen - Wikipedia

    en.wikipedia.org/wiki/Fraction_of_Inspired_Oxygen

    Fraction of inspired oxygen (F I O 2), correctly denoted with a capital I, [1] is the molar or volumetric fraction of oxygen in the inhaled gas. Medical patients experiencing difficulty breathing are provided with oxygen-enriched air, which means a higher-than-atmospheric F I O 2. Natural air includes 21% oxygen, which is equivalent to F I O 2 ...

  3. Oxygen window - Wikipedia

    en.wikipedia.org/wiki/Oxygen_window

    Production of CO 2 is usually about the same as consumption of O 2 on a mole-for-mole basis, but there is little rise of P CO 2 because of its high effective solubility. Levels of O 2 and CO 2 in tissue can influence blood flow and thereby influence washout of dissolved inert gas, but the magnitude of the oxygen window has no direct effect on ...

  4. Fick principle - Wikipedia

    en.wikipedia.org/wiki/Fick_principle

    Determination of the oxygen consumption of the peripheral tissues is more complex. The calculation of the arterial and venous oxygen concentration of the blood is a straightforward process. Almost all oxygen in the blood is bound to hemoglobin molecules in the red blood cells. Measuring the content of hemoglobin in the blood and the percentage ...

  5. Winkler titration - Wikipedia

    en.wikipedia.org/wiki/Winkler_titration

    1 mole of O 2 → 2 moles of MnO(OH) 2 → 2 mole of I 2 → 4 mole of S 2 O 2− 3. Therefore, after determining the number of moles of iodine produced, we can work out the number of moles of oxygen molecules present in the original water sample. The oxygen content is usually presented in milligrams per liter (mg/L).

  6. Gas blending - Wikipedia

    en.wikipedia.org/wiki/Gas_blending

    The mole fraction is also called the amount fraction, and is the number of molecules of a constituent divided by the total number of all molecules in the mixture. For example, a 50% oxygen, 50% helium mixture will contain approximately the same number of molecules of oxygen and helium.

  9. Breathing gas - Wikipedia

    en.wikipedia.org/wiki/Breathing_gas

    A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
