I have never seen a bleeding wound that did not yield to direct pressure, and that includes a virtual amputation of an arm, as well as quite a few open fractures. I can't even recall having to use a pressure point.
You are correct. QC makes direct pressure more effective. I have seen their data and thhe new version causes almost immediate clotting. BUt yes direct pressure is still the proven method.
JIm,
Sorry but can't give up my sources.
