If cardiac output increases what happens to BP and why?

If cardiac output increases, blood pressure (BP) typically increases as well, assuming vascular resistance remains constant. This is because blood pressure is determined by the product of cardiac output and systemic vascular resistance (BP = CO x SVR). An increase in cardiac output means more blood is being pumped into the circulatory system, leading to higher pressure in the arteries. However, if the blood vessels dilate significantly, it could mitigate the rise in BP.
