Comparison of Respiratory System Models: Gas Exchange and Control of Oxygen Levels

This session discusses the modeling and comparison of the respiratory system with the circulatory system, analyzing changes in temperature and pressure, mechanical and electrical models of the respiratory system, oxygen transfer to tissues through the circulatory system, and the control of blood oxygen levels.

  9. Charles’ or the Ideal gas Law Pressure is inversely proportional to volume and directly proportional to absolute temperature and quantity of gases. p * v = n * R * Twhere p = pressure in mm Hg; v =volume in ml; n = quantity of gas in moles; T = temperature in degree Kelvin; R = universal gas constant (62.37)Some standard abbreviations:STPD = Standard Temperature at 273 K, Pressure at 760 mmHg, Dry gas no water vaporBTPS = Body Temperature at 310 K, Pressure at 760 mmHg, Saturated H2O vapor at 47 mmHg

  10. Dalton’s LawThe total gas pressure of a gas mixture is equal to the sum of the partial pressures of the component gases:Total pressure P = PO2 + PN2+ PCO+ PH2O=159 + 597 + 0.3 + 3.7= 760 mm HgGas Composition = 20.9%+ 78.5% + 0.04% + 0.5% =100%
