Huether & mccance (2017) chapter 5, chapter 24 (shock- p. 637-652), review ards. Barry et al. (2014) chapter 19, chapter 69, chapter 70 musculoskeletal fractures p. 1819-1939. 1 l of water= water 1 kg. Intracellular and extracellular are the two major fluid compartments in the body. Intracellular fluid is about 42 % body weight. Isotonic: fluids with the same osmolality as the cell interior. Hypotonic: solutions in which the solutes are less concentrated than they are in cells. Hypertonic: solutions are more concentrated than they are in the cells. In blood vessels, hydrostatic pressure is the blood pressure generated by the contraction of the heart. Oncotic pressure: (colloid osmotic pressure): is osmotic pressure exerted by colloids in solution. Protein is the main colloid contributing to cop. The amount and direction of movement are determined by the interaction of 1) capillary hydrostatic pressure, 2) plasma oncotic pressure, 3) interstitial hydrostatic pressure.
