Circulation is the fourth priority in the MARCH protocol, focusing on controlling hemorrhage that was not stopped by tourniquets and preventing hypovolemic shock. Our circulation collection includes pressure dressings like the OLAES Modular Bandage, ETD Emergency Trauma Dressings, ESMARK bandages, compression bandages, elastic wraps, and hemostatic agents including QuikClot, CELOX, ChitoGauze, and Axiostat. These products work in concert to achieve hemostasis through mechanical pressure and chemical clotting acceleration. Essential for IFAKs, trauma kits, and professional medical bags, our circulation products are trusted by military operators, law enforcement, fire/EMS, and prepared civilians. All products are evidence-based and selected for proven performance in traumatic bleeding scenarios.
