Document Summary
Imbalance between supply and demand of oxygenated blood (perfusion problem**) Arterial: ischemia, necrosis, popliteal and femoral, caroid artery, can cause tia/stroke. Vascular assessment: patches: pulse, appearance, temp, cap reill, hardness of skin, edema, sensaion. Organic: structural damage to vessels, plaque builds up to occlusion. Risk factors: smoking (makes platelets sick together), high bp, diabetes, increased lipids, age, lifestyle, stress afects ability to constrict. Plaque in artery can build up in heart and cause early demenia. Pain sensaion: may not feel stubbing of toe. Frost bite: may not noice unil its too late. Appearance of lower extremiies: mild/no edema, decreased/no hair on legs, decreased/no pulse, long cap reill, white/pale when elevated, red/blue when in dependent posiion. Progresses slowly, skin not normal, painful to walk. Muscle atrophy in legs, paient doesn"t want to walk. Delayed wound healing in legs, issue necrosis. Arterial ulcers must be treated: healing takes long because of reduced blood low.
