Fluid Balance and IV Therapy Flashcards
How much of the body is water?
60%
Fluids in the body are affected by
- Age
- Gender
- Body Fat
ICF
Intracellular Fluid
ECF
Extracellular fluid
How much internal water is ICF and ECF?
ICF= 2/3
ECF includes
- Intravascular fluid
- Interstiatial Fluid
- Transcellular Fluid
Diffusion
Movement of melecules from high to low concentraion
Diffusion is ___ transport
Passive
Osmosis
Movement of fluid from low to high solute concentration
Diffusion need no…
protein channels or ATP
Osmosis needs no… but does need…
Atp
protein channels
Both osmosis and Diffusions attempt to reach…
Equal distribution/Homeostasis
Active transport moves
Na and K with the use of ATP
Na moves ____ and K moves ____ cells
and how many of each?
3 Na moves out of cells
2 K moves into cells
ATP =
Adenosine Triphosphate
Hydrostatic/Oncotic Pressures moves…
fluid from the capillaries to the interstitum (tissue)
Hydrostatic pressure acts as a___
Moves fluid…
- pushing forces
Out of Capillaries
Oncotic pressures acts as a ___
Moves fluid…
- Pulling force
- From tissue into capillaries
Distribution of Water is cut into ___ spaces
3
First fluid spacing:
Normal distribution of fluid in ICF and ECF
Second fluid spacing:
Abnormal accumulation of interstitial fluid (Edema)
Third Spacing:
Example:
- FLuid accumulates in a pocket that is serving no purpose
- Ascitis: excess fluid in abdomen
Ascites can be caused by:
- Liver issues
- Intestinal Blockage
- Heart issues
Edema
Accumulation of interstitial fluid within tissues
