 Volume of trapped gas recovered from emphysematous lungs

Lung number(A) Volume recovered simultaneously from two spiracles (l)(B) Volume recovered from single upper lobe spiracle (l)(C) Volume recovered from single lower lobe spiracle (l)
*Not statistically significantly different.
Column A is the gas recovered via two spiracles simultaneously after full lung inflation and complete passive deflation via the bronchus. Columns B and C are the volumes of trapped gas recovered from single upper and lower lobe spiracles respectively after full lung inflation and complete passive deflation via the bronchus.
