I don't doubt anything anymore, but that seems unlikely. What I wonder is if you catch a certain part of a deer's lung if it would still have partial use of that lung. For example, in this case if you caught the top lobe of the lung toward the back and the deer fell over maybe the way the deer was laying would create a seal over the wound and prevent the lung from filling with blood. It is possible that the deer could survive some time with partial use of one lung. This is all theory.

Any thoughts?
