Arterial Insufficiency Flashcards
Learn
plaque/artherosclerosis leads to
ischemia
ischemia is
reduced oxygenated blood flow to tissues or heart
ischemia/reduced blood flow effect on tissues
less oxy and nutrients so dead tissues/necrosis skin atrophy delayed healing wound infection arterial ulcers
goal of peripheral arterial disease
inc oxygenated blood flow to lower extremities
goal of peripheral venous disease
no oxy blood problem;get deoxy blood back to heart
rest pain
no gravity flow oxy blood to lower extremity; worse at night, supine position doesn’t promote gravity flow
rest pain cause
elevated legs, supine position
peripheral artery disease swelling?
no edema b/c no oxy blood to legs/foot
peripheral artery disease skin temp, color?
temp cool; color pallor no oxy, think dead body
PAD wound depth?
deep. no oxy so break down tissue leads to depth of injury
PAD pain?
painful b/c tissue nerve damage
PAD wound appearance
even edges round, PVD moist water runs not neat
PAD wound drainage
dry, little drainage, no oxy so no fluid build up
PAD expected BP changes
normal bp legs ^ arms. PAD bp legs less than brachial
3 causes blood vessel obstruction
atherosclerosis, glucose, platelets
proper pulse assessment
bilateral
PAD expected pulse of affected lower extremity
absent or +1 vs +2 normal
atherosclerosis of brain arteries leads to
stroke/cerebrovascular accident CVA
atherosclerosis of brain, kidney, heart, peripheral?
not peripheral
PAD pain location
distal to blockage/narrowing of arteries
hyperhomocysteinemia
deficit Vit B12, B6 and folic acid
hyperhomocysteinemia risk
thrombosis if elevated level
cramping/ischemic pain with exercise
intermittent claudication pain in calf
intermittent claudication remedy
rest, resolves within 10 minutes
rest pain
supine at night no gravity flow so low arterial pressure
lack oxy and nutrients: 3 symptoms of lower extremities
no hair growth, dry skin, brittle/thick nails
increased lactic acid level effect on circulation
decrease flow of oxy and blood in arteries
describe PAD pain
shooting, sharp, stabbing, burning
poikilothermia
body temp adjust to environment/ cool on palpitation, raynaud’s
paresthesia
abnormal sensation; numbness, tingling, pins and needles b/c low oxy
PAD leg elevation
pallor color
PAD leg dependent position (hanging off bed)
rubor
