IVF

Annotations:

• Diffusion: solutes move
• Osmosis: Water moves
• Osmolarity

1. Hypotonic

   Annotations:

   • Not for the hypotensive. Treats depleted ICF
   1. <270 mOsm/L

      Annotations:

      • Will Lower osmolarity of blood. Pulls fluids out of ECF n2 ICF
   2. Any Saline <0.9%. Any Dextrose < 5%
      1. Cell Rehydration
   3. Fluid pulled from ECF into ICF
2. Extra cellular fluid

   Annotations:

   • Outside the cells. Blood, lymph, bone and connective tissue water. Interstital/ transcellular fluids. (CSF,synovial fluid, pleural fluid
   1. Fluid outside cells
3. Intracellular Fluid
   1. Fluid within cells
4. Isotonic

   Annotations:

   • Wont cause a shift in either fluid compartment. Treating Hypotension.
   1. =270-300mOsm/l
   2. NS 0.9%. D5W. LR

      Annotations:

      • D5- has calories to decrease catabolism. Once calories are depleted the fluid becomes hypotonic. Could cause Cerebral edema. Caution with Head injurys
      • LR contains Na+,K+,Ca+, Cl-. Ca+ can cause incompatibilities LR can be helpful in treating metabolic acidosis. Monitor for overtreatment leading to alkolosis
   3. No fluid shift
5. Hypertonic

   Annotations:

   • Interstital Edema.
   1. >300 mOsm/L
   2. Dextrose Solutions > 5%. Saline solutions >0.9%

      Annotations:

      • Monitor for FVE
      1. Interstitial edema
   3. Fluid moves from ICF into ECF
6. Sterile h2o
   1. Never used as infusion, only dilution

      Annotations:

      • Could cause cells to explode, too hypotonic
