Editorial team. Bleeding is the loss of blood. Bleeding may be: Inside the body internally Outside the body externally Bleeding may occur: Inside the body when blood leaks from blood vessels or organs Outside the body when blood flows through a natural opening such as the ear, nose, mouth, vagina, or rectum Outside the body when blood moves through a break in the skin. Seek medical care right away for any abdominal, pelvic, groin, neck, or chest wound.
If organs are showing through the wound, do not try to push them back into place. Cover the injury with a moist cloth or bandage. Apply gentle pressure to stop the bleeding in these areas. You may have symptoms such as: Blood coming from an open wound Bruising Bleeding can also cause shock, which may include any of the following symptoms: Confusion or decreasing alertness Clammy skin Dizziness or light headedness after an injury Low blood pressure Paleness pallor Rapid pulse increased heart rate Shortness of breath Weakness Symptoms of internal bleeding may include those listed above for shock as well as the following: Abdominal pain and swelling Chest pain Skin color changes Blood coming from a natural opening in the body may also be a sign of internal bleeding.
These symptoms include: Blood in the stool appears black, maroon, or bright red Blood in the urine appears red, pink, or tea-colored Blood in the vomit looks bright red, or brown like coffee-grounds Vaginal bleeding heavier than usual or after menopause. Calm and reassure the person. The sight of blood can be very frightening. If the wound affects just the top layers of skin superficial , wash it with soap and warm water and pat dry. Bleeding from superficial wounds or scrapes abrasions is often described as oozing, because it is slow.
Lay the person down. This reduces the chances of fainting by increasing blood flow to the brain. When possible, raise up the part of the body that is bleeding. Remove any loose debris or dirt that you can see from a wound. DO NOT remove an object such as a knife, stick, or arrow that is stuck in the body.
Doing so may cause more damage and bleeding. Place pads and bandages around the object and tape the object in place. 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. When it has stopped, tightly wrap the wound dressing with adhesive tape or a piece of clean clothing.
Do not peek to see if the bleeding has stopped. If bleeding continues and seeps through the material being held on the wound, do not remove it. Select personalised ads. Apply market research to generate audience insights. Measure content performance. Develop and improve products.
List of Partners vendors. You can stop bleeding with just your hands, but it's significantly easier and better for the patient if you have gauze, too. We get small irritations and minor leaks all the time, and the body has to stop that leak to allow time for the injury to heal. Bleeding stops when the blood coming out of the wound clots coagulates. Clotting happens as platelets, tiny particles in the bloodstream, interact with proteins.
The proteins trigger the platelets to become fibrous and sticky—think spiderweb. Platelets stick together across an opening in the blood vessel the wound and plug the hole. The clot also provides a foundation for new tissue to grow. It's kind of like a microscopic scaffolding. Indeed, the whole process is similar to a construction project meeting a river. If you've ever walked along a stream or a canal, you may have noticed that debris and algae tend to collect in places where the water doesn't flow very fast.
In places where the river or stream runs quickly, nothing gathers. Bleeding is similar. In a wound from which blood is flowing freely, clots are unlikely to form. The rush of blood out of the hole doesn't allow the platelets any time to stick together. To help a clot form and bleeding to stop , we have to slow the flow down. This is done in four ways:. You may be looking at how we started this answer and thinking, "Why gauze?
