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
•decrease of filling pressure and by Frank- Starling principle decrease of CO
•Clinical symptoms:  vasomotor syncope
•Therapy: infusion of physiological solution

CIRCULATORY FAILURE
•        BP = CO  x TPR
•CO decrease:
üvasodilatation of venous system - sudden periphery vasodilatation
•Clinical symptom: vasovagal syncope

CIRCULATORY FAILURE
•        BP = CO  x TPR
•CO decrease:
•
ülower pumping function of the heart
•Started reflex reaction on periphery vessels and tissues
•Resultes: cardiogenic shock

CIRCULATORY FAILURE
•        BP = CO  x TPR
•TPR decrease:
ütoxic vasodilatation (by histamin-allergy)
üDysbalance of autonomy nervous system – sympathetic part – decrease  of sympathetic tone of
vessels
