Which hemodynamic values are expected in cardiogenic shock?

In the context of cardiogenic shock, the hemodynamic values reflect the heart's inability to pump effectively, leading to inadequate circulation and tissue perfusion. This results in a low cardiac output (CO) because the heart is struggling to generate sufficient blood flow.

The central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP) are both elevated in cardiogenic shock due to the increased volume and pressure backing up into the heart and lungs as a result of poor cardiac function. High CVP indicates elevated pressure in the right atrium, suggesting that blood is not efficiently being moved forward; meanwhile, high PCWP indicates fluid overload in the pulmonary circulation, consistent with congestive heart failure scenarios often accompanying cardiogenic shock.

Systemic vascular resistance (SVR) is typically high in cardiogenic shock. The body compensates for the inadequate cardiac output by constricting blood vessels to maintain blood pressure, leading to increased afterload on the heart.

Thus, the correct values for a patient experiencing cardiogenic shock include low CO, elevated CVP and PCWP, and high SVR, accurately reflecting the pathophysiological changes occurring in this state.
