How do you distinguish between arterial and venous insufficiency?
Although arterial and venous insufficiency share many of the same characteristics and symptoms, the two conditions are actually quite different. Venous insufficiency refers to a breakdown in the flow of blood in our veins, while arterial insufficiency stems from poor circulation in the arteries.
What is the difference between pressure ulcer and venous ulcer?
Venous skin ulcers are caused by poor circulation in the legs caused by damaged valves that prevent blood from flowing the wrong way, allowing blood to pool in the legs. Pressure ulcers, on the other hand, are caused by sustained pressure on an area of the body, which cuts off blood flow.
What does an arterial ulcer look like?
Arterial ulcers have a distinct “punched out” appearance and are typically circular with a red, yellow, or black coloration. They are usually extremely painful. Venous ulcers are often painless unless they are infected.
What is the difference between arterial bleeding and venous bleeding?
Arterial bleeding is when you bleed from an artery. Your arteries bring oxygen-rich blood away from your heart and to your body’s organs. Venous bleeding. In venous bleeding, blood flow comes from a vein.
What is the difference between peripheral arterial disease and peripheral venous disease?
The two diseases differ in several key ways. PAD means you have narrowed or blocked arteries — the vessels that carry oxygen-rich blood as it moves away from your heart to other parts of your body. PVD, on the other hand, refers to problems with veins — the vessels that bring your blood back to your heart.
Whats the difference between arterial and venous?
Typically, in a double circulation system, arteries of the systemic circulation carry blood away from the heart and veins carry blood towards the heart. The main difference between arterial and venous blood is that arterial blood is oxygenated whereas venous blood is deoxygenated.
Are arterial ulcers stasis ulcers?
Leg ulcers are skin lesions with full-thickness loss of epidermis and dermis on the lower extremities. Among a wide variety of etiologies for chronic leg ulcers, four common types are venous stasis ulcers, arterial ulcers, diabetic neuropathic ulcers, and pressure ulcers.
Are diabetic ulcers venous or arterial?
* Diabetic foot ulcers are often due to both arterial disease (involving the microcirculation as well as large vessels) and neuropathic disease.
Are arterial ulcers wet or dry?
Typically, the ulcer itself is small, round, and smooth, with a “punched out” appearance and well-defined borders. The wound may be shallow or deep. The wound base typically is pale, dry, necrotic, and without granulation tissue (see photograph of an arterial ulcer on the foot).
What is a arterial leg ulcer?
An arterial ulcer is an ulcer due to inadequate blood supply to the affected area (ischaemia). Arterial ulcers tend to occur on the lower legs and feet, and may be acute, recurrent or chronic. Ulcers may have multiple contributing factors; these ‘mixed ulcers’ constitute roughly 15% of all leg ulcers.
What is the main difference between arterial and venous blood quizlet?
Arteries are thicker due to a higher and more fluctuating blood pressure. Veins are thinner. Peripheral veins have valves to keep blood flowing in one direction toward the heart.
What is the best treatment for arterial ulcers?

What causes arterial ulcers?
