Mechanism of action
Liberal fluid strategies involve administering larger volumes of intravenous fluids perioperatively or in critical care settings to expand circulating blood volume and improve tissue perfusion. This approach aims to optimize cardiac preload and oxygen delivery to vital organs, though the optimal fluid volume remains clinically debated.
