1. Introduction to Fluid Volume Disorders A fluid volume disorder is a clinical state characterized by a significant deviation in the body’s total water content and the corresponding equilibrium of essential electrolytes. The human physiological system relies on a precise volume of fluid to maintain adequate blood pressure, ensure continuous cellular perfusion, and facilitate the … Read more
