Osmolality amount of particles within a fluid contributing to a
fluid's concentration
- High osmolality: hypertonic solution
- balanced osmolality: isotonic solution
- Low osmolality: hypotonic solution
Hydrostatic pressure A force pressing outward against a surface
Osmotic pressure an inward pulling pressure towards a higher
concentration
Diffusion passive movement of particles down a concentration
gradient
Active Transport using energy to move electrolytes across cell
membrane
Fluid moves to the cell in the following 1. Vascular System
order: 2. Capillary Membrane
3. Interstitial Area
4. Cell Membrane
Osmolality Imbalance the blood is too concentrated/dilute
, Labs to Measure Osmolality Osmolality Specific- most accurate!!
Urine Specific Gravity-
Hgb & Hct- the higher the Hct, the higher the
osmolality
Sodium levels- water follows salt!! If sodium is
elevated, then osmolality is elevated
Types of IV Fluids
Hypertonic Solution - Concentrated and usually given when Blood
Osmolality is Low
- Combination of Dextrose & Saline together W/
Water makes these fluids hypertonic
- Help draw fluid back into the Vascular Space=
decreasing edema
- Low Blood Osmolality + Hypertonic Fluid = Isotonic
Blood
- D5 NaCl
- D5 LR
- D5 0.45% NaCl
Isotonic Solution - Used for dehydration
- Equal balance Particles and Water
- Normal Blood Osmolality + Isotonic Fluid = No
change in Isotonic Blood
-0.9% NaCl
- LR
