Simplifying Fick

WebThe diffusion coefficient of gases is important when comparing different gases in the lung. Let's take CO2 and O2. They are similar in molecular weight, but CO2 is about 20x more soluble than O2 in plasma, and therefore diffuses faster! This shows how the diffusion coefficient is important. WebNov 24, 2024 · Start learning for free. According to Fick’s law, the rate of gas transfer across a tissue plane or membrane (Vgas) is directly proportional to the difference in partial pressures of the gas on the two sides of the membrane (P1 – P2) and the membrane’s diffusing capacity (D M ). And the membrane’s diffusing capacity, D M, is dependent ...
