If the bleeding is from a larger arterial vessel, the bleeding can be stopped by the acupressure method in emergency situations. The acupressure method is to press the proximal end of the artery, do not press for too long, and relax appropriately after a while to avoid tissue ischemia and necrosis. If available, go to the hospital for surgical vascular suture treatment as early as possible, which is the root of the treatment. Clinically, you can also use pressurized gauze compression or compression with a tourniquet to stop bleeding, both of which should be noted that if the time is too long, you must pay attention to proper relaxation to avoid causing tissue ischemia and hypoxia and causing necrosis. For large arterial bleeding, hemostasis is the first step that needs to be performed, because once the bleeding is too large, it can lead to shock and cause death in the patient.
