The relation between percent change in blood volume and cardiac output (CO) after volume preload with 1.5 L lactated Ringer’s solution (〇), 0.5 L hydroxyethylstarch solution, 6% (●), and 1.0 L hydroxyethylstarch solution, 6% (×) in parturients at term. [15]. Exponential increase in CO was observed after volume preloading
