Initial Response to Trauma•Rapid loss of fluid, electrolytes and blood causing hypovolemia•Hypovolemia causes decreased perfusion of organs and cells resulting in anoxiaof organs and cells resulting in anoxia, organ ischemia and failure•Cells convert to anaerobic glycolysis and lactic acid accumulates.Response to StressHypovolemicShock Shock - Ebb PhaseEbb Phase•Decreased cardiac output•Decreased O consumptionDecreased O2consumption•Decreased blood pressure•Decreased body temperature•Decreased insulin:glucagon ratioVasopressinGould B.
