AI - textbook Flashcards
explain elastic artery movement during systole / diastole
systole = expand as blood enter
diastole = returns to normal
pressure distribution from arterial system to arteriole
arterial = 90-100 mmHg
arterioles = 25-35 mmHg
pressure on venous side of capillary
15 mmHg
population thtat Buerger’s or thromboangiitis is seen in
young adults who smoke heavily
explain cholesterol deposition
biochemical changes and intimal cell injury
- body attempts to repair the intimal cells and ends up building up blood products that block the artery
amount of vessel stenosis related to intermittent claudication
50%
amount of vessel stenosis related to ischemic rest pain
70%
those with CAD experience a ______ likelihood of developing ______ than those without
higher
AI ulcer
explain the negatives of smoking
nicotine = vasoconstriction
increased CO in system
increased rate of clot formation
nicotine increases cholesterol deposition
increased oxygen mismatch between delivery and demand in tissue
tell me about the popliteal artery? where does it come from? where does it go, cotton eyed joe?
continuation of superficial femoral artery
popliteal fossa
location of posterior tibial artery
between tendons of flexor digitorum longus and flexor hallicus longus
superior to medial malleolus near posterior medial portion of tibia
location of dorsalis pedis
over second toe between extensor hallucis longus and extensor digitorum longus
how to hold doppler when assessing artery
45° to skin
how to conduct an ABI test
find brachial and posterior tib art
inflate cuff until swooshing on doppler isn’t heard (+20mmHg)
note the pressure at which the sound returns
a drop of ______ on a repeat ABI test indicates ________
0.15
peripheral arterial obstructive disease progression
