Pathophysiology
Clinical meaning
Advanced peripheral vascular disease represents diffuse atherosclerosis with significant stenosis or occlusion of lower extremity arteries. Critical limb ischemia (CLI) occurs when rest blood flow cannot meet baseline metabolic needs, leading to ischemic rest pain, non-healing wounds, and tissue necrosis requiring revascularization to prevent amputation. Connect PVD Advanced to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
