Is Co2 Diffusion Limited

Oxygen, carbon dioxide and nitrous oxide are perfusion-limited.

Which gases are diffusion limited?

Because the rate of CO diffusion across the membrane is the principal factor limiting further blood transport of carbon monoxide away from the lungs, pulmonary exchange of carbon monoxide is referred to as “Diffusion-limited”.

Is CO2 transported by diffusion?

Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body.
