During fluid resuscitation, the primary goal is to restore intravascular volume, particularly in cases of hemorrhagic shock or significant fluid loss. As fluids are infused into the circulatory system, the increased volume can lead to improved venous return to the heart. This subsequently enhances cardiac output, which is the amount of blood the heart pumps in a minute. With an increase in cardiac output, there is typically a corresponding increase in blood pressure.

This relationship is particularly significant in trauma care, where maintaining adequate blood pressure is critical for ensuring that vital organs receive sufficient blood flow and oxygen. The infusion of fluids raises the pressure within blood vessels, countering hypotension that may occur due to blood loss.

While it's essential to monitor a patient's response to fluid resuscitation closely, and individual responses can vary based on numerous factors (such as existing injuries or medical conditions), in the context of general resuscitation principles, it is accurate to state that the blood pressure tends to go up with effective fluid infusion.
