Venous Diease Flashcards
How does respiration affect the lower extremities?
inhale=flow is reduced
exhale=flow occurs
How does respiration affect the upper extremities?
inhale=flow occurs
exhale=flow is reduced
How do muscle impact venous flow?
the contraction of arm/leg muscles squeezes veins and propels blood towards the heart

when fluid is displaced when pressure is applied
What is non pitting edema?
when tissue is so swollen the fluid does not move with pressure (much worse)
What is a deep venous thrombosis (DVT)?
blood clot within deep veins
causes increased venous pressure
stretches walls
damages valves
Where do DVTs most commonly occur?
calf or where IVs were placed in UE
What is Virchows Triad (causes of DVT)?

- Hypercoagulability (hormone therapy, chemo)
What are the signs and symptoms of acute DVT?
- swelling
- pain
- erythema (redness)
- warmth
What does acute DVT look like?
-hypo echoic appearance
-spongy
-dilated vessel
-thrombus poorly attached
-abnormal doppler
-vein not compressible
