WHAT IS SHOCK A physiologic state characterized by Inadequate tissue perfusion imbalance between the delivery of and requirements for oxygen and substrate Clinically manifested by Hemodynamic disturbances Organ dysfunction
WHAT IS SHOCK • A physiologic state characterized by • Inadequate tissue perfusion • imbalance between the delivery of and requirements for oxygen and substrate • Clinically manifested by • Hemodynamic disturbances • Organ dysfunction
CLASSES OF SHOCK THE HEMODYNAMIC EQUATION BP CO SVR (blood pressure) (cardiac output) (systemic vascular resistance) CO stroke volume(SV)x heart rate SV end diastolic volume(EDV)-end systolic volume(ESV) (preload) affected by afterload/inotropy/ EDV= venous return ESv
