NURS 3444 Lecture 6: Fluid and Electrolyte Imbalance
Document Summary
Capillaries hydrostatic pressure increases filtration by pushing fluid and solute out of the capillaries, while capillary oncotic pressure (also known as colloid osmotic pressure) pulls fluid into the capillaries and/or prevents fluid from leaving. Capillaries oncotic pressure (also known as colloid osmotic pressure)increases filtration by pushing fluid and solute out of the capillaries, while capillary hydrostatic pressure pulls fluid into the capillaries and/or prevents fluid from leaving. Flows through skin, insensible fluid loss through skin. Normal water balance (goal = equilibrium in 24 hours) Might be higher than with an adult because sporadic breathing. Total body water in different age groups. Younger = has higher chance of insensible loss. Brain and skin = higher interstitial fluid. Newborn age is defined as 30 days (1 month) max. High metabolic rate = requires generous fluid intake. The major body fluid compartments at various ages.
