Calculating fluid strength Index - the amount of formaldehyde gas measured in grams and dissolved n 100 ml. of water

Four factors: Strength of concentrated fluid (C) Volume in ounces of concentrated fluid (V) Strength of diluted fluid in the tank (C prime) Volume in ounces of diluted fluid (V prime) Hypertonic - Having the higher osmotic pressure of two solutions. Causes blood cells placed in it to shrivel. Hypertonic solutions should be used when embalming edematous case Hemolysis – the swelling and bursting of blood cells in a hypotonic salt solution Hypotonic - Having the lower osmotic pressure of two fluids / Cause blood cells placed in it to swell Hypotonic solutions should be used in embalming “normal cases”.

Remember: One gallon is 128 ounces. So two gallons is 256

Basic Formula C x V = C prime x V prime OR Strength of concentrated fluid (the index) Times volume of concentrated fluid (Number of ounces) Strength of diluted fluid (desired percentage) Times volume of diluted fluid (number of ounces)

Example How much of a 20 index fluid will it take to make two gallons of a 1 index (or 1 percent) injection solution? Solving for V. C x V = C prime x V prime 20 x V = 1 x 256 (one gallon is 128 ounces. So two gallons is 256) V= 256 divided by 20 V = 12.8 ounces C x V = C prime x V prime OR Strength of concentrated fluid (the index) Times volume of concentrated fluid (Number of ounces) Strength of diluted fluid (desired percentage) Times volume of diluted fluid (number of ounces) Strength of concentrated fluid (C) Volume in ounces of concentrated fluid (V) Strength of diluted fluid in the tank (C prime) Volume in ounces of diluted fluid (V prime)

Example If you use 16 oz. of 30 index fluid, how many gallons of a 2.5% solution would you have? C x V = C prime x V prime 30 x 16 = 2.5% x V prime 480 = 2.5V prime 480/2.5= 192 One gallon is 128 ounces One gallon and 64 ounces or 1.5 gallons C x V = C prime x V prime OR Strength of concentrated fluid (the index) Times volume of concentrated fluid (Number of ounces) Strength of diluted fluid (desired percentage) Times volume of diluted fluid (number of ounces) Strength of concentrated fluid (C) Volume in ounces of concentrated fluid (V) Strength of diluted fluid in the tank (C prime) Volume in ounces of diluted fluid (V prime)

Example What percentage dilute solution is created by adding 32 ounces of a 28 index fluid in enough water to make four gallons of solution? 32 x 28 = C prime x 512 896 = C prime/512 896/512= 1.75 percent / index C x V = C prime x V prime OR Strength of concentrated fluid (the index) Times volume of concentrated fluid (Number of ounces) Strength of diluted fluid (desired percentage) Times volume of diluted fluid (number of ounces) Strength of concentrated fluid (C) Volume in ounces of concentrated fluid (V) Strength of diluted fluid in the tank (C prime) Volume in ounces of diluted fluid (V prime) One gallon is 128 ounces. So two gallons is 256 ounces. Four gallons would be 512 ounces.
