I had originally heard the theory that there was more tissue mass ventral-side of the lungs (vs. dorsal of the lungs) and thus proning would allow the patient to breathe easier without as much tissue mass resting on top. (Seems too simplistic to be true, no?)  The VQ mismatch theory is more interesting.  Proning has been anecdotally very helpful since early March iirc.
