Bleeding The most common cause of external bleeding is an injury. Any type of cut, scrape, or fall where blood is coming from an open wound is regarded as external bleeding. The type of blood vessels damaged in a cut determines the speed at which blood is dispersed from the injured area. External bleeding is divided into three types. Capillary bleeding is the most common type of external bleeding, which occurs when blood oozes from the capillary.
It is easiest form of external bleeding to control and is typically not serious. The second and more serious type of bleeding is venous bleeding, which transpires when a vein has been severed and blood flows steadily. Most veins collapse when cut, which aids in controlling this type of external bleeding until medical attention can be received. The most serious and last type of external bleeding is arterial bleeding. As the bloods pumps at a faster rate it is less likely to clot, as a result this leads to a large amount of blood loss. First Aid for bleeding begins by calming and reassuring the victim.
Next lay the victim down to reduce the chance of fainting by increasing the blood flow to the brain. Elevate the bleeding area when possible. Clean and remove loose dirt away from the wound. If an object such as a knife, stick, or arrow becomes embedded in the body, do not remove it.
Doing so may increase the amount of bleeding and cause more damage. Place gauze and bandages around the object and tape the object in place. Put pressure directly on an external wound with a sterile bandage, clean cloth, or even a piece of clothing. Direct pressure is best for external bleeding, except for an eye injury.
Maintain pressure until the bleeding stops. Do not peek at the wound to see if the bleeding has stopped. If bleeding continues and soaks through the material being held on the wound, do not remove it. Simply place another cloth over the first one. Be sure to seek medical attention.
Prevention from bleeding requires a person to use common sense and keep knives and sharp objects away from small children. Keeping your vaccinations up to date is another method of prevention. Generally, the tetanus immunization is renewed every 10 years. Another type of bleeding is a nose bleed. A nose bleed is a loss of blood from the mucous membranes that line the nose. Nosebleeds are common and occur most due to minor ir rations or colds.
Air moving through the nose can dry the mucous membrane and cause the nose to bleed when rubbed or blown. First aid for a nose bleed is to have the victim sit down and gently squeeze the middle of the nose with the thumb and finger. The victim should lean forward to avoid swallowing blood. Prevention for nosebleeds include keeping your home cool and using a vaporizer.
Nasal saline can also prevent nose bleeds from occurring.
