Key Points Of First Aid For Hemostasis Of Trauma

When performing on-site first aid for trauma, timely and effective control of bleeding is one of the important links for successful rescue. The danger of bleeding is also related to the ruptured blood vessels. Generally speaking, arterial bleeding is the most dangerous because of its fast bleeding speed, which often appears as outward spray; venous blood only appears as blood constantly flowing out, and the blood is darker than arterial blood, so the danger is relatively small, but this is not absolute. For example, when the large veins in the neck rupture, negative pressure suction can easily cause air embolism and endanger life; the least dangerous is capillary bleeding, which appears as blood oozing out from the entire wound surface, and the amount of bleeding is very small, which will not cause serious consequences.
