  12. 12. Electrolytes<br />
  13. 13. ELECTROLYTE BALANCE<br />
  14. 14. Contain different electrolytes because the cell membranes separating the two compartments have selective permeability.<br />Contain different solutes, concentration levels are about equal when balance is maintained. <br />
  15. 15.
  16. 16. FLUID MOVEMENT<br />A mechanism that regulates fluid and electrolyte balance.<br />Body fluids are in constant motion.<br />Nutrients , waste products, and other substances get into and out of cells, organs, and systems.<br />Influenced by membrane permeability and colloid osmotic and hydrostatic pressures. <br />

  21. 21. Osmosis<br />Movement of water across a semipemeable membrane from an area of low solute concentration (less concentrated) to an area of high solute concentration (more concentrated).<br />
  22. 22. Capillary filtration and reabsorption<br />Filtration – movement of substances from an area of high hydrostatic pressure to an area of lower hydrostatic pressure<br />Hydrostatic pressure – pressure at any level on water at rest due to weight of the water above it. <br />Pushes fluids and solutes through capillary wall pores and into the ISF.<br />Capillary Reabsorptionby the osmotic or pulling force of albumin (Colloid Osmotic/Oncotic Pressure) - pulling force of albumin in the capillaries, attracting water in from the interstitial space<br />

  25. 25. CORRECTING IMBALANCES<br />
  26. 26. Osmolarity<br />Concentration of a solution.<br />Expressed in milliosomols of solute per liter of solution (mOsm/L)<br />Same osomolarity as other body fluids about 300 mOsm/L<br />
  27. 27. Three Main Types of IV Solutions<br />Isotonic<br />Hypotonic<br />Hypertonic <br />
  28. 28. Isotonic Solutions(240-340mOsm)<br />Solution has the same solute concentration (or osmolality) as normal blood plasma (290mOsm) and other body fluids<br />Solution stays where it is infused, inside the blood vessel<br />Expands the intravascular compartment<br />Does not affect the size of the cells<br />Solution maintains body fluid balance<br />

  30. 30. Isotonic Solutions<br />
  31. 31. Isotonic Solutions<br />
  32. 32. Isotonic Solutions<br />Nursing considerations<br />Monitor patient for signs of fluid overload especially in patients with CHF and hypertension.<br />
  33. 33. Hypotonic Solutions<br />Solution has a lower osmolarity than serum (less than 240 mOsm/L)<br />Solution causes a fluid shift out of the blood vessels into the cells and interstitial spaces<br />Solution hydrates cells while reducing fluid in the circulatory system<br />Ex.: ½ NSS (0.45% NaCl)<br />
  34. 34. Hypotonic Solutions<br />
  35. 35.
  36. 36. Hypotonic Solutions<br />Nursing considerations<br />Administer cautiously<br />Solution can lower blood pressure<br />Do not give if these solutions if the patient is at risk for:<br />ICP from cerebrovascular accident<br />Head trauma<br />Neurosurgery<br />
  37. 37. Hypertonic solutions<br />Solution has an osmolarity higher than serum(>340mOsm/L)<br />Causes the solute concentration of the serum to increase pulling fluid from the cells and the interstitial compartment into the blood vessels<br />Reduces the risk of edema, stabilizes blood pressure, and regulates urine output<br />

  39. 39.
  40. 40. Hypertonic Solutions<br />
  41. 41. Hypertonic Solutions<br />Nursing considerations<br />Monitor your patient for circulatory overload<br />Solution can be irritating to the vein<br />
  42. 42. Two Main Groups of IV Solutions<br />Crystalloids<br />Colloids<br />
  43. 43. Crystalloids<br />Are isotonic and remain isotonic in the vasculature and are therefore effective volume expanders for a short period of time.<br />Ideal for patients who need fluid volume replacement<br />Ex.: Lactated Ringer’s (LR), Normal Saline (NS)<br />
  44. 44. Colloids<br />Used to increase vascular volume rapidly drawing fluid from the interstitial and intracellular compartments into the vascular compartment. <br />They work well in reducing edema (as in pulmonary or cerebral edema) while expanding the vascular compartment. <br />Examples: albumin, mannitol, dextran, hetastarch, gelafundin, Haesteril<br />
  45. 45. Colloids<br />Dextran<br />Polysaccharide fluid<br />Albumin<br />Natural plasma protein from donor plasma<br />Mannitol<br />Sugar alcohol substance<br />Hetastarch<br />Synthetic colloid made from starch<br />
