CIRCULATORY FAILURE
• The main function of circulation is perfusion of organs

BP = CO x TPR

CIRCULATORY FAILURE
BP = CO x TPR CO decrease:
ülower volume in circulation – lower venous return üvasodilatation of venous system ülower pumping function of the heart

CIRCULATORY FAILURE
BP = CO x TPR TPR decrease:
ütoxic vasodilatation üDysbalance of autonomy nervous system – sympathetic part – decrease of sympathetic tone of vessels
