  1. hemorrhaging (blood loss) volume loss HR x SV x PVR = BP O2 carrying capacity loss (RBC) heat loss (hypothermia) sympathetic response β adrenergic stimulation α adrenergic stimulation hypoxia skeletal muscle contraction/relaxation (shivering) peripheral vasoconstriction (increased PVR) tachycardia (increased HR) peripheral vasoconstriction (increased PVR) anaerobic cellular metabolism increased cellular respiration C6H12O6 + O2 CO2 + H2O + ATP HR x SV x PVR = BP (compensatory shock) only glycolysis (lactic acid build-up) increased CO2 production end-organ failure CO2 + H2O  H2CO3  HCO3- + H+ acidosis
