In hypovolemic shock, which hemodynamic changes are expected?

Explanation:
In hypovolemic shock, the failing volume coming back to the heart reduces filling of the heart, so preload falls. With less filling, the heart pumps out less blood, leading to a drop in cardiac output. To compensate and maintain arterial pressure, the body increases systemic vascular resistance through sympathetic vasoconstriction, so SVR goes up. This pattern—low preload, low cardiac output, and high SVR—fits the scenario described.
