the wound is letting off blood
They have cut or open artery and strong pressure must be used. A tourniquet is the choice.
Many things affect the color of blood when it hits air. The only way to determine what type it is to test it.
If it is spurting, an artery has been cut and there is no time to lose. The bleeding must be stopped very quickly or the patient will die.
Because theres obviously blood under the skin and when there is an open wound the blood flows out.
There is a lot of dark coloured blood. If it was an artery, the blood would be pulsing out, and bright red. Veins carry blood that needs oxygen back to the heart and lungs so oxygen can be replenished. This is why the blood is dark. Well oxygenated blood is bright red (in the arteries)
easy answer: the worst one. more complex answer: evaluate each wound for location, size and impact to life. the small wound over the carotid artery that is spurting blood 10 feet is worse than the big leg wound that is mostly clotted.
This would be arterial bleeding - bright red pertains to oxygen-rich blood and the squirting is because of the pressure from the heart. Venous blood will appear dark, and oxygenated blood from the arteries will appear bright red in color.
If there is a wound with poor blood circulation leches can help heal the wound. The leches are attached to the wound. Their bite, with it's blood thinning properties and sucking of the blood, can help supply blood to the wound aiding in its healing.
Bright red blood is a sign of highly oxygenated blood. Pain, fast pulse rate and rapid respirations are generally the cause. Bright red blood is also a sign that an artery has been severed. Blood is red because it contains a chromophore (colored compound) called heme. The electronic structure of heme is such that it can reversibly bind certain other molecules, one of which is oxygen. The oxy-heme complex is bright red. If the blood came from an artery, it was probably already bright red. If it came from a vein, the heme will be a sort of dark purplish-red, but as soon as it hits the oxygen in the atmosphere, it will bind and form the bright red oxy-heme complex, so regardless of where you cut yourself, the blood is going to be bright red. When you give blood at a blood bank, the blood is drawn from a vein, and flows into a bag which keeps the oxygen out. This blood will be the dark purplish-red color of the deoxygenated heme.
If an artery is cut while you have a fast heartbeat it will flow similar to that. However it does not look like what you see in the movies.
Oozing blood would be coming from the capillaries. Blood from the veins would be flowing freely out of the wound and blood from the arteries would be spurting out.The wound would be near a major artery.
