Surgical management Thromboectomy Umbrella filter Ventilation- Act of breathing (moving air in and out of lungs) Respiration - Process of gas exchange at cellular level (in alveoli) Oxygenation and Tissue Perfusion Lungs: Oxygen intake Heart, blood vessels and RBCs: Oxygen delivery to cells/tissue Needs of body tissues for O 2 is balanced by intake & delivery systems Normal compensatory mechanisms : Mild O 2 need increased: increased depth and rate of respiration Greater need: increased depth and rate of respiration and increased BP and HR to deliver needed O2 MUSCULOSKELETAL: Osteoblasts Primary bone-producing cells Ossification and calcification Respond to parathyroid hormone Osteocytes Mature bone cells Key regulators of both bone formation and resorption Maintain bony matrix Osteoclasts “bone-chewing” cells bone resorption Remodeling: Repair bone injuries Three phases:

PTH -Secreted when blood calcium decreases Increases blood calcium by increasing: Bone resorption Kidney reabsorption Intestinal absorption through vitamin D Decreases blood phosphate by decreasing: Kidney reabsorption Calcitonin Released by the thyroid when blood calcium is high Inhibits release of calcium from bone Inhibits osteoclast activity Inhibits calcium and phosphate kidney reabsorption Soft tissue injuries: Contusion: muscle Muscle bruise; produced by blunt force Common sites thigh and arm Pain, swelling, and discoloration: ecchymosis Strains: muscle Stretching or partial tear injury to the muscle/tendon unit Common sites: back, cervical region of spine, elbows, shoulders Pain stiffness, swelling local tenderness (inflammatory response) Sprain: supporting ligaments Partial or complete tear or rupture of ligament Any joint may be sprained but ankle, knee, elbow most common Pain stiffness, swelling local tenderness (inflammatory response) --Treatment
