WebAug 29, 2024 · The rate of diffusion (or effusion) of a gas is inversely proportional to the square root of the mass of its particles. When a gas had particularly large particles (or is particularly dense), it will mix more slowly with other gases, and oozes more slowly from its containers. Clinical Significance Boyle’s Law Webby two major techniques: plethysmography (utilizing adult and infant body-boxes), and gas dilution or wash-out techniques. The most commonly used are helium (He) dilution (a closed-circuit method), and nitrogen (N 2) washout (in its modern form, an open-circuit method). Other gases can be employed, and, over the past decade,

Industry Guidelines

WebBody plethysmography uses Boyle's Law to determine lung volumes, whereas inert gas dilution and nitrogen washout use dilution properties of gases. After determination of FRC, expiratory reserve volume and inspiratory vital capacity are measured, which allows the calculation of the RV and TLC.

WebIf the TGV is greater than the predicted FRC, it indicates the presence of trapped gas (alveolar air trapping, blebs, pneumothorax, etc). Body plethysmography is also used to measure airway resistance and conductance, as well as lung compliance.
