heat loss(hypothermia)
increased cellular respirationC6H12O6 + O2 CO2 + H2O + ATP
skeletal muscle contraction/relaxation
(shivering)
peripheral vasoconstriction(increased PVR)
sympathetic response
HR x SV x PVR = BP
(compensatory shock)
increased CO2 production
CO2 + H2O H2CO3 HCO3- + H+ acidosis
α adrenergic stimulation
β adrenergic stimulationhypoxia
volume loss
HR x SV x PVR = BP
O2 carrying capacity loss
(RBC)
end-organ failure
peripheral vasoconstriction(increased PVR)
tachycardia(increased
HR)
