Fluid Movement Flashcards
Lesson 6
dilution attained as the embalming solution is mixed in embalming machine
primary dilution
determined by embalming analysis and prepared by embalmer
primary dilution
to determine strength of primary dilution
C x V = C’ x V’
strenght of concentrated fluid; index
C
amount of concentrated fluid; vol. of fluid
V
strength of diluted fluid; strength of solution (%)
C’
amount of diluted fluid; total vol.
V’
1 bottle =
16 oz.
ounces in a gallon
128
recommended strenght of injection fluid
1.5-2%
recommended injection fluid
1 gal. diluted fluid for every 50lbs.
weakening of embalming fluid by fluids in the body both vascular and interstitial
secondary dilution
conditions that cause secondary dilution to vary
edema; dehydration
will increase amount of secondary dilution
edema
will decrease amount of secondary dilution
dehydration
movement of embalming (arterial) solution from point of injection throughout the arterial system and into the capillaries
fluid distribution
movement of molecules/other particles from area of greater concentration to area of lesser concentration until a uniform concentration is reached; from intra to extravascular
fluid diffusion
positive intravascular pressure causing passage of embalming fluid through the capillary wall to mix with intersitial fluids; movement from intra-extravascular position
pressure filtration
passage of a solvent from a solution of lessert to one of greater solute concentration when 2 solutions are seperated by a semipermeable membrane
osmosis
process by which most embalming chemicals move from interstial fluids through the cell wall and into the cell
osmosis
solution having an equal concentration of dissolved solute to that it is compared
isotonic solution
solution having lesser concentration of dissolved solute than the solution to which it is compared
hypotonic solution
will move toward the more concentrated solution; would want in a dehydrated case to plump them up
hypotonic solution
solution having greater concentration of dissolved solute than solution to which it is compared
hypertonic solution
will not move; instead other solution will move toward it to create equilibrium; would want in edema case
hypertonic solution
seperation of substances in solution by the difference in their rates of difuffusion through a semipermeable membrane
dialysis
extravascular movement of preservative fluids by gravitational force to the dependent areas of body
gravitational filtratration
distention of superficial vessels; large vol. of blood drainage; reduction of intravascular blood discoloration, dye tracing, loss of elasticity of tissues (firmness), drying of tissues, tissue distention, bleaching of tips
signs of fluid distribution and diffusion
methods of improving fluid distribution
increase rate of flow; increase injection pressure; restrict the drainage; massage body; lower the arms
