Max Dodge, board member of National Stop the Bleed Month, visits with Ginger about how Medic Mindset listeners can get involved with the Stop the Bleed campaign. She ended up talking to him about bleeding control for an hour.

Point of clarification from Max: “The pressure needed to occlude arterial flow is the same as the pressure exerted on the vessel during systole. However, more pressure is needed to ensure occlusion (say +10% like in transcutaneous pacing) and even more pressure is needed to translate force applied at the skin to force applied on the artery. 300mmHg is considered relatively safe for tissue (skin, muscle, nerves, etc in the compression area) and 500mmHg is considered relatively unsafe (likely to cause skin ulceration or nerve palsy). I think effective occlusion can occur at less than 300mmHg, but for reliability sake 300mmHg is a good goal.”

Paper referenced by Max: Tourniquets and occlusion: the pressure of design.
