Perfusion and diffusion limitations in middle ear gas exchange: the exchange of $CO_{2}$ as a test case Universiteit Antwerpen
A long standing debate on perfusion/diffusion limitations in the context of middle ear (ME) gas exchange was revisited using data obtained from previous iso-pressure gas-exchange measurements in different mammals. We tried to determine whether the exchange of CO2 in the ME is limited by perfusion or by diffusion by comparing the mass specific cardiac output (View the MathML source) and the mass specific initial CO2 flow rate into air-washed MEs ...
