External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
Symptoms classically affect a leg and typically develop over hours or days, [20] though they can develop suddenly or over a matter of weeks. [21] The legs are primarily affected, with 4–10% of DVT occurring in the arms. [11] Despite the signs and symptoms being highly variable, [5] the typical symptoms are pain, swelling, and redness.
Blue toe syndrome is a situation that may reflect atherothrombotic (clots resulting from the build-up of fats, cholesterol, and other substances in and on the artery walls) [1] microembolism, causing transient focal ischaemia, a temporary blockage of blood flow to the brain or spinal cord, [2] occasionally with minor apparent tissue loss, but without diffuse forefoot ischemia.

The U.S. Food and Drug Administration has cleared Cresilon's gel to quickly control bleeding, the privately held company said on Thursday, potentially giving emergency medical technicians and ...
Flexing the toes and feet and extending on tiptoes can all be very useful in detecting perforator vein incompetence. These movements unleash a muscle contraction which compresses deep veins. If a perforator valve is incompetent, then a reflux from the deep to the superficial through the perforator vein will be registered.
Putting pressure and/or dressing to a bleeding wound slows the process of blood loss, allowing for more time to get to an emergency medical setting. Soldiers use this skill during combat when someone has been injured because this process allows for blood loss to be decreased, giving the system time to start coagulation. [10]
Blocking the holes in the bone typically stops bone bleeding. This can be done by mechanically blocking the holes (tamponade effect), or by inducing a blood clot to form. In the past the easiest and most common way to stop bone bleeding was to apply bone wax, which is made from beeswax. The bone wax is smeared across the bleeding edge of the ...
