👉 The whole fluid, also known as total blood volume (TBV), is a comprehensive measure of the amount of blood in the circulatory system, encompassing all components including red blood cells (RBCs), white blood cells (WBCs), plasma, and platelets. It is crucial for maintaining adequate circulation, delivering oxygen and nutrients to tissues, and removing waste products. The whole fluid is typically expressed in milliliters (mL) or liters (L) and includes both the liquid portion of plasma and the cellular components. Changes in whole fluid volume can significantly impact blood pressure, cardiac output, and overall cardiovascular function, making it a key parameter in diagnosing and managing various medical conditions.
