How do you calculate isotonicity?
Calculations for preparation of isotonic solution:
multiply the quantity of each drug in the prescription by it's sodium chloride equivalent E , and subtract this value from the concentration of sodium chloride which is isotonic with body fluids (0.9 gm per 100 ml).How much NaCl to make 50 mL of isotonic solution?
50 x 0.009 = 0.45 g of sodium chloride in 50 mL of an isotonic sodium chloride solution • Step 3.What is isotonicity with example?
It may also pertain to a condition or property of a solution that has the same tonicity as the other solution with which it is compared. For example, blood serum is isotonic to a physiologic salt solution. Solutions that have the same tonicity will result in no net flow of water across the cell membrane.- Isotonic solution: A solution that has the same salt concentration as cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.
