All hemorrhage control is ultimately direct pressure.
🕖 Reading Time, 3 minutes
A tourniquet puts direct pressure on an artery.
Wound packing puts direct pressure at the point of bleeding. As long as the pressure is higher than systolic blood pressure, the bleeding will stop. Sometimes that’s easier said than done. XSTAT makes wound packing a lot easier…
Kerlix Gauze packing can generate up to 197 mmHg at the bottom of the wound and 45 mmHg on the sides.
XSTAT can generate 156 mmHg and 123 mmHg, respectively.
Although it’s unclear XSTAT is better than gauze packing done by a well-trained packer, it’s essentially an expert wound packer in a tube, and it’s faster.
Wound packing is a trained skill.
