Venous Insufficieny Flashcards
Learh
Venous Pathophysiology
weak valves>low venous return>inc vein pressure
venous valves purpose
prevent deoxy blood backflow, keep moving to heart
thrombus formation
clump, clotting, coagulation cascade, stop bleeding
venous pressure: 3 symptoms
edema, venous ulcers, venous dermatitis
venous ulcers interventions
elevate, compression, exercise
brown skin color due to
iron seeping thru veins
venous ulcers: 3 characteristics
superficial, pink, uneven edges, above ankle
why venous ulcer superficial vs arterial ulcer
arterial necrosis, dead tissue, deeper wound
peripheral venous disease pulses
normal, no problem with oxy in tissues +2
venous insufficiency pain
ache, cramp, dull b/c water congestion vs artery sharp
venous peripheral disease skin appearance
edema, think, tough, brawny
how to promote venous circulation
exercise, intermittent compression therapy
calf function
act as pump for blood, contract push blood to heart
obese patient, postsurgical wear compression socks
always
VTE venous thromboembolism aka
DVT deep vein thrombosis
DVT description
blood clot in venous system usually lower extremity
Virchow’s triad 3 causes thrombosis formation
statis of blood, injury to vessel, hypercoagulation
injury to blood vessels include
smoking, trauma
coagulation purpose
platelets form together to clot and stop bleeding
pregnancy risk factor DVT
uterus presses against IVC, inc in clotting factors
atrial fibrillation risk factor DVT
artery not contracting regular, blood static>clot
Homan’s sign
calf pain on dorsiflexion of foot when raised
DVT clinical manifestations
unilateral pain, swell/warm extremity, inc calf size
clot care
bed rest, ambulate can dislodge clot, no compression
