PERIPHERAL VASCULAR ASESSMENT Flashcards
(18 cards)
thick walled structures that carry blood from the heart to the tissues
arteries
Arterial Pulses (Arms)
Radial, Brachial, Ulnar
Arterial Pulses (Legs)
Popliteal, Femoral, Dorsalis Pedis, Posterior Tibial
Thin walled structure that permits rapid and efficient transport of nutrients to the cells and removal of metabolic wastes
Capillaries
has one way bicuspid valves that prevent blood from seeping backward
vein
carry 90% of the venous return from the lower extremities
deep veins of the legs
includes great saphenous veins, small saphenous veins and communicating veins; one way valves
superficial veins
normal for capillary refill time
<2
common in men and smokers
bueger’s disease
inability of fascia to expand.
s/sx: pallor, paresthesia, paralysis, pain, pulselessness, poikilothemia
compartment syndrome
autoimmune disorder wherein there is excess in collagen formation
scleroderma
test done prior ABG (arterial blood gas)
allen test
emerges to into the uper thigh from beneath the inguinal ligament 1/3 of the distance from the pubis to the anterior superior illiac spine
common femoral artery
passes through a deep proportion of the popliteal space lateral to midplane
popliteal artery
congenitally absent in 10% individuals
dorsalis pedis
used to assess the adequacy of the arterial supply to the leg. It is performed in two stages. With the patient supine, elevate both legs to an angle of 45 degrees and hold for one to two minutes. Observe the color of the feet. Pallor indicates ischaemia. It occurs when the peripheral arterial pressure is inadequate to overcome the effects of gravity.
Bueger’s Test
often used in the diagnosis of deep venous thrombosis of the leg. A positive indication lf pain at dorsiflexion of the foot) is thought to be associated with the presence of thrombosis.
Homans Sign
measurement of blood flow in the leg arteries; compares the systolic BP in the arm with the ankle; determines the extent of peripheral arterial disease.
