What does homeostasis mean?
Proper equilibrium
What is intracellular fluid?
Fluid inside the cell 2/3
What is extracellular fluid?
Fluid outside of the cell 1/3
What does osmosis mean?
Movement of water through a semi permeable membrane that doesn’t allow solute to cross
What does diffusion do?
High to low
What does hydrostatic pressure mean?
Pressure of the blood against a vessel wall
What does active transport mean?
Using energy across a concentration grading
What does tonicty mean?
Measurement of concentration of IV solutions compared with osmolaity of body fluids
What does osmolaity?
Concentration of solutes in the body
What does hypo-osmolar mean?
What does hyper-osmolar mean?
What does iso-osmolar mean?
Cell swell ( too little water outside )
Suitable ( perfect )
Cell shrinks ( too much water outside )
What are some methods of fluid replacement ?

Colloids
What does crystalloids do?
what are the classifications ?
Is it short or long term maintenance ?
What are examples ? (3)
Treat dehydration and electrolyte imbalance
Isotonic
Hypotonic
Hypertonic
Short term
Dextrose 5, normal saline, lactated ringers
What is colloids?
Are they able to pass the membrane?
Meaning ?^(known as)
This causes the blood to?
What are examples (2)
Protein that increases osmolarity without dissolving in the solution
No
They are plasma expanders
Blood volume increases
Dextran 75, Albumin 5%
Notes
Blood and blood products
Plasma platelets
Cryoprecipitate
Maximum rate of infusion is 4 hours per unit
