Doppler ultrasound is the gold standard for what system?
venous system
Venous filling time is a predictor for?
arterial insufficiency
medial mal and medial lower leg are common sites for?
venous insufficiency ulcers
what is the breakdown pressure for pressure ulcers
32mmHg
Bismouth is cytotoxic to which cells?
inflammatory cells - pts with venous insufficiency ulcers are prone to these responses
Semipermeable films should not be used on
highly exudatiing or infected wounds
semipermeable foams are permeable to
gas but not bacteria
semipermeable foams are good to use on
pressure ulcers or slough covered partial and full thickness wounds
Which dressing has the lowest infection rate?
hydrocolloids
hydrocolloids are most often used to treat?
pressure ulcers
hypergranualtion may be seen with which type of dressing
hydrocolloids
alginate dressings react with serum and wound exudate to form?
a hydrophilic gel
Tunica media modulates vessel diameter and is innervated by
the sympathetic nervous system
Thickening/hardening of arterial walls is
arteriosclerosis
Ankle Brachial index can diagnose
Peripheral Artery disease
An ABI of 1.1-1.3 is
vessel calcification
What is a normal ABI?
0.9-1.1
ABI of 0.7-0.9 is interpreted as
mild to moderate arterial insufficiency
ABI of 0.5-0.7 is interpreted as
moderate arterial insufficiency - intermittent claudication
ABI of <.5 is interpreted as
severe arterial insufficiency–rest pain
ABI <0.3 is interpreted as?
rest pain and gangrene
venous filling time of <5 seconds is interpreted as
venous insufficiency
venous filling time of 5-15 seconds is interpreted as
normal
venous filling time of >20 seconds is interpreted as
arterial insufficiency
