The rate of oxygen diffusion affected by the pressure gradient of carbon dioxide is a false statement.
Why the rate of oxygen diffusion is affected by the pressure gradient of carbon dioxide is a false statement?
- Fick’s law gives us a number of factors that affect the rate of diffusion of a gas through a fluid:
- The partial pressure difference across the diffusion barrier
- The solubility of the gas
- The cross-sectional area of the fluid
- The distance molecules need to diffuse
- The molecular weight of the gas
- The temperature of the fluid – is not important within the lungs and can be assumed to be[tex]$37^{\circ} \mathrm{C}$[/tex]
- This difference between the rate of diffusion of the individual molecules is compensated for by the large difference in partial pressures of oxygen, creating a larger diffusion gradient than that of carbon dioxide.
- However, this means that in disease states which impair the ability of the lungs to adequately ventilate with oxygen, oxygen exchange is often compromised before that of carbon dioxide.
So, the rate of oxygen diffusion affected by the pressure gradient of carbon dioxide is a false statement.
