8

NS Normal Saline =

0.9% sodium chloride solution

9

Electrolytes (such as KCl {potasium chloride})

added to the IV fluid and are measured in milliequivalents (mEq) per liter (L)

10

Solution strength

is written as a number next to the letter of the solution component abbreviation
the number may be written as a subscript

11

infusion equipment

electronically regulated IV solutions
manually regulated IV solutions

12

electronically regulated infusion solutions

infusion device
special tubing
alarm
powered by direct current or rechargeable batteries

13

examples of electronically regulated infusion solutions

volumetric infusion controller (depend on gravity to maintain the desired flow rate as mL per hour or drops per minute)
infusion pump (does not depend on gravity and maintains the flow rate by displacing fluid)
syringe pump

14

manually regulated infusion solutions

primary IV tubing
secondary IV tubing

15

Primary IV tubing

IV solution bag
drip chamber
injection port(s)
roller clamp

16

secondary IV tubing (Piggyback)

Manual IV tubing sets are calibrated according to the drop factor (the number of drops per mL) as 10, 15, 20 macrodrops per mL (gtt/mL) and 60 microdrops per mL (microgtt/mL)
