WTF? The lungs don't work like a heart's chambers. The lungs are essentially two independent bags in a cavity. They are both connected to the same whole (the throat) and when the diaphragm expands (i.e., the bottom of the cavity) the expanded cavity size causes a drop in pressure, thus sucking air into the lungs. To exhale, the diaphragm contracts, causes the cavity's size to shrink, increasing pressure, and forcing the air out of the lungs.
See here for details.

The only why to stop the lungs from sucking in air or expelling it, is to close off the wind pipe, or destroy the chest cavity. As I stated above, unless it is a really big wound, it is doubtful that a stab to the chest will stop one from making noise.
