Web25 jul. 2024 · The area of the blood-gas barrier in the human lung is approximately 50–100 m 2, and the thickness is less than 0.3 µm in many places, so the dimensions of the barrier are well suited to diffusion. In addition, the rate of gas transfer is proportional to a diffusion constant, which depends on the properties of the tissue and the particular gas. WebGas Transfer in the Lung and Lung function Testing. THE FICK PRINCIPLE This says that: “The volume of gas which diffuses per unit time across a tissue sheet is 1. proportional to the area of the sheet, 2. inversely proportional to the thickness of the sheet 3. Proportional to the difference in partial pressure of the gas on the two sides 4.
