peripheral artery disease
disease: peripheral vascular disease (arterial or venous); characterized by cold sensitivity & often people with CT disorders
Raynaud’s disease
disease: inflammation w/ thrombosis causing decreased blood supply to hands/feet
Buerger’s disease

chronic venous insufficiency (CVI)
s/s: leg edema, varicose veins, aching, cramps, itching, redness, skin ulcers on LEs
chronic venous insufficiency (CVI)
disease: inflammation and clotting of veins
thrombophlebitis & DVT

leukemia
when body can’t supply enough oxygen to body’s tissues, causes ____ or _____
hypovolemic shock and organ failure
