  13. 13. Packaging of IV Fluids Most packaged in soft plastic or vinyl bags. Container provides important information:  Label lists fluid type and expiration date.  Medication administration port.  Administration set port.

  15. 15. Do not use any IV fluids after their expiration date; any fluidsthat appear cloudy, discolored, or laced with particulate; or any fluid whose sealed packaging has been opened or tampered with.
  16. 16. IV Administration Sets Macrodrip—10 gtts = 1 ml, for giving large amounts of fluid. Microdrip—60 gtts = 1 ml, for restricting amounts of fluid. Blood tubing—has a filter to prevent clots from blood products from entering the body. Measured volume—delivers specific volumes of fluids.
  17. 17. IV Administration Sets (continued)  IV extension tubing—extends original tubing.  Electromechanical pump tubing —specific for each pump.  Miscellaneous—some sets have a dial that can set the flow rates.
