TYPES of FLUID

1. ISOTONIC Fluid – no movement of fluid.2. HYPOTONIC Fluid – fluid will enter the cell, the cell will shrink.3. HYPERTONIC Fluid – fluid will go out from the cell, the cell will shrink.

Tonicity of IV Fluids

Definition: The tonicity of an IV solution relates to how the red blood cells respond when the solution is added.

Isotonic Fluid moves equally between compartments

Cell volume remains the same

Fluid is moving equally into and out of the compartments

IV FLUIDS

Hypotonic

Fluid moves into the cells

Fluid moves into RBC causing cell rupture (hemolysis)

Fluid moves from the vascular space into the cells.The major problems with administering hypotonic IV solutions is the hemolyis and swelling of the cells in the brain that occurs

Hypertonic

Fluid is pulled out of the cells

Fluid moves out of the cell causing crenation (shrinking) of the RBC

Fluid is pulled out of the cells and into the vascular system, so increases intravascular volume.
