Document Summary
Always look at labs before giving any fluids. About 60% of the adult body is made up of fluids. Infants are at an increased risk for imbalances and are effected most by fluid shifts. Total body h2o decreases from birth to old age: intracellular : fluid inside the cell. ( k+ is most abundant) 2/3 of all fluid in the body is. Types of fluid intracellular: intravascular: capillary blood , 3l plasma 3l blood components ( rbc, fluid around the cell, transcellular: synovial fluid, intraocular fluid, digestive fluid, cerebrospinal fluid, extra cellular: three types of extra cellular fluid. Loss of extra cellular fluid into space that does not contribute to equalibrium. Third spacing can cause hypovolemia presented by : low blood pressure, decreased urine output, increased heart rate. Gaines: dietary intake of fluid, food, enteral feeding, parenteral fluids. Losses: sweating, kidney and urine output #1, evaporation, breathing, stool. They have reduced homeostatic mechanisims: cardiac, renal, respiratory fx.
