Document Summary
Chapter 69- shock, systemic inflammatory response syndrome (sirs), and multiple-organ. Syndrome characterized by decreased tissue perfusion and impaired cellular metabolism. Results in an imbalance between the supply and demand for oxygen and nutrients. When a cell is in a state of hypoperfusion the demand for oxygen and nutrients exceeds the supply. Classified as blow blood volume (cardio-genic and hypovolemic shock) or maldistribution of blood flow (septic, anaphylactic, and neurogenic shock) Can occur with a normal blood pressure and hypotension can occur without shock. Early intervention reduces mortality and early effects of o2 deprivation on the cells are reversible. Lab orders: cardiac enzymes, troponin levels, ecg, chest xray, echocardiography, abgs, electrolytes. Treatment: restore blood flow to the myocardium by restoring the balance between o2 supply and demand, stabilize airway and improve myocardial pump infusion, ^ systemic. Lab orders: serial measurements of hemoglobin and hematocrit level, urine specific gravity, serum electrolytes, blood gasses, lactic acid.
