Q
What is the equation for Fick’s Law?
A
Rate of diffusion= (SA x Concentration gradient)/ Diffusion path difference
2
Q
what is needed for the maximum rate of diffusion?
A
large SA + concentration gradient
minimum diffusion path difference
3
Q
what happens as the DPD increases?
A
Diffusion slows down very quickly
4
Q
What does peak flow measure?
A
The maximum rate air can be expelled from the lungs
5
Q
