How do you stop an arterial bleed?
Correspondingly, how do you stop external bleeding?
Put pressure directly on an outer wound with a sterile bandage, clean cloth, or even a piece of clothing. If nothing else is available, use your hand. Direct pressure is best for external bleeding, except for an eye injury. Maintain pressure until the bleeding stops.
Also to know is, how serious is an arterial bleed?
Most life-threatening bleeding is arterial; however, severe venous bleeding is possible. Arterial blood is bright red and spurts out of a wound in time with the patient's pulse; in contrast, venous blood is darker and while it does not spurt, blood loss can be heavy.
If you inject into an artery you may bleed to death or lose a limb. You will know when you inject into an artery as when you pull the plunger back the blood is bright red and you feel a burning sensation. The blood can also appear frothy and the plunger can be forced back by the pressure of the blood.
