Compression bandage hemostasis, also known as compression hemostasis, is a fast way to stop bleeding both in life and in surgery, for example, in the case of subcutaneous skin tissue or superficial small arterial bleeding, simple finger compression or gauze compression can be used urgently, of course, the compression must be given the appropriate pressure, insufficient pressure will not play a role in hemostasis, mainly through compression to reduce the amount of bleeding, waiting for the body’s physiological clotting The main purpose is to reduce the amount of bleeding by compression and wait for the body’s physiological clotting to complete. In addition, emergency compression bandaging is often used to stop bleeding in case of accidental hemorrhage, for example, if the bleeding site is not visible, deep, or surrounded by important organ structures that cannot be directly pinched by hand to stop bleeding, gauze can be used as a substitute for compression to stop bleeding, which can be removed after several hours or days, and fist compression can be used to stop bleeding if finger pressure or gauze compression is not effective. Emergency pressure bandaging to stop bleeding is only a temporary measure, so it is still necessary to go to a professional hospital to find the site of bleeding and then to stop bleeding completely.
