Identify and explain types of external bleeding for first aid ?

1. Arterial bleeding: Arterial bleeding occurs when an artery is damaged and blood is spurting out in a rapid, pulsating manner. This type of bleeding is bright red in color and can be life-threatening if not treated promptly.

2. Venous bleeding: Venous bleeding occurs when a vein is damaged and blood is flowing out steadily. This type of bleeding is dark red in color and is usually easier to control than arterial bleeding.

3. Capillary bleeding: Capillary bleeding occurs when the smallest blood vessels, called capillaries, are damaged. This type of bleeding is slow and oozing, and is typically seen in minor cuts and scrapes.

4. External bleeding from an open wound: This type of bleeding occurs when the skin is broken and blood is flowing out of the wound. It can be arterial, venous, or capillary depending on the size and location of the wound.

5. External bleeding from a puncture wound: Puncture wounds occur when a sharp object penetrates the skin and causes bleeding. This type of bleeding can be difficult to control as the object may still be lodged in the wound, preventing the blood from clotting properly.

It is important to apply direct pressure to the wound using a clean cloth or bandage to control external bleeding. Elevating the wound above the level of the heart can also help reduce blood flow. If bleeding is severe or does not stop after applying pressure, seek medical attention immediately.
