Basics of Fluid therapy
A. Anatomy and Physiology of Body Fluid Compartments: Remember the “60-40-20” rule of body water. 1. Total body water: 60% (50-70%) of Total Body Weight Greater in lean individuals because fat contains little water Greatest percentage in newborns, then decreases with age 2. Intracellular fluid (ICF): 40% of Total Body…
