NUR 324 Lecture 8: Vascular Disorders and Problems with Peripheral Circulation
Document Summary
Anastomosis two thing sown back together (blood vessels) Angioplasty clean out arteries and vessels. Ankle-brachial index (abi) blood pressure of the leg (how well blood is purfusing) Rest pain with rest still have pain in calf. Rubor color of skin, influx of blood to an area. Intermittent claudication cramp in calf muscle while walking. Complications of vascular system: arterial disorders, venous disorders, cellulitis.

Role of circulation and microcirculation: arteries and arterioles, veins and venules, capillaries. Left-side of heart (cid:271)lood to all other (cid:271)od(cid:455) tissues right-side of heart. Function of vascular system: blood flow parameters: metabolic rate of organ/tissue, available oxygen, function of tissue, delivery/exchange of oxygen/carbon dioxide, vasodilation, vasoconstriction based on metabolic requirements, occurrence of ischemia, oxygen extraction differs by organ. Gerontological issues: stiffening of vessel walls normal part of aging, not usual to have sudden onset. Impaired blood flow (cid:271)lood does(cid:374)"t (cid:373)o(cid:448)e as eas(cid:455)
