Fluid & Electrolytes Flashcards
Intravascular- fluid inside blood and lymph vessels
Interstitial- fluid between cells
Types of extra cellular fluid.
Fluid located within cells
Intracellular fluid
Stretch or pressure receptors located in the major arteries or veins.
Baroreceptors
The proportion of dissolved particles (solute) in a volume of liquid.
Osmolarity
Concentration of dissolved substances in a given weight of fluid rather than a given volume.
Osmolality
Chemical compounds that hold a charge and partially separate in a solution.
Electrolytes
8.9-10.1 mg/dl
Normal serum calcium.
135-145 mEq/L
Normal serum sodium levels
3.5-5.3 mEq/L
Normal serum potassium
1.4-1.75 mEq/L
Normal magnesium levels
2.5-4.0 mg/dl
Normal phosphorus levels
The movement of molecules from an area of higher concentration to a lower concentration.
Diffusion
The movement of liquid through a semi permeable membrane
Osmosis
The process by which ions are moved from an area of lower concentration to a higher concentration. (Requires ATP)
Active transport.
The transfer of water and dissolved substances through a semipermeable membrane from a region of high pressure to low pressure.
Filtration
The attraction of water by undissolved particles, helps keep fluid within blood vessels.
Osmotic pressure.
Fluid that has a concentration of solute that is less than that of blood plasma.
Hypotonic
Fluid that has a concentration of solute that is greater than that of blood plasma.
Hypertonic
Any substance that can donate free H+ ions to a solution.
Acid
Any substance that can take H+ from a solution.
Base
Substances that help prevent large changes in the PH if a substance.
Buffers
7.37-7.43
Normal PH
36-44mm Hg
Normal PaCO2
80-100 mmHg
Normal PaO2
22-26 mEq/L
Normal HCO3-
