Card Set Information
What gases are diffusion limited?
What gases are perfusion limited?
Niitrous oxide (N
(more common pefusion than diffusion)
What causes O
to switch from perfusion to diffusion-mediated?
Diffusion capacity decreases
Fibrosis causes thickness to increase, so less oxygen can get through and the time to get through increases
Partial Pressure is maintained throughout capillary
If the molecular weight drops and solubility increases, what happens to Diffusion coefficient?
It will increase
**This means that the specific gas will be more readily absorbed
What does body size, gender and age do to diffusion capacity (D
Body size = increase
Gender = Male = increase
Age = decrease
What are the three methods of gases being used in the body?
