The immobilized patient experiences a decreased circulating fluid, pooling of blood in lower extremities, and a drop in systolic blood pressure. Three factors contribute to thrombus formation, which include loss of integrity of vessel wall, abnormalities of blood flow, and changes in clotting fac-tors/increased platelet activity.
