The chapter “Introduction to Shock” reviews the definition, classification, epidemiology, pathophysiology, clinical manifestations, and therapeutic goals of shock. It examines the cardiovascular factors and mechanisms leading to impaired oxygen delivery and its effect on end organ perfusion and the pathogenesis of shock. This chapter reviews the compensatory mechanisms in shock that cause the signs and symptoms, along with organ manifestations, reported in patients with acute circulatory failure. This chapter also discusses the limitations and benefits of different monitoring modalities during shock management including central venous pressure, mixed venous oxygen saturation, and echocardiography. Finally, it considers therapeutic goals and treatments to restore perfusion and reverse the shock state.
