1. Chapter 8Calculation of Basic IV Drip Rates

2. Types of Intravenous Fluids • D5W = D5%W • D5S = D5 %0.9NS • D51/2NS = D5 %0.45NS • NS = 0.9%NS • ½NS = 0.45% NS

3. Intravenous Drip Factors • Microdrip = 60 gtt/mL • Macrodrip need to check package • 10 gtt/mL • 15 gtt/mL • 20 gtt/ml • To calculate IV drip rates, must know this information

4. Electric Infusion Pumps • Volume for infusion • Rate for infusion • Turn pump on

5. Intravenous Piggybacks on Electronic Infusion Pumps • Secondary volume • Secondary rate • Turn pump on

6. Calculating Basic IV Drip Rates • Number of milliliters to infuse x tubing factor = drops per minute or gtt/min number of minutes to infuse • When the order reads “hour,” convert to minutes by multiplying by 60 (60 minutes = 1 hour)

7. Calculating IV Drips for Infusion Pump • Total number of milliliters ordered = mL/hour Number of hours to run

8. Question Order: 1000 mL D5W at 120 mL/hour Available macrodrip 15 gtt/mL What is the drip factor in drops per minute? A. 30 B. 31 C. 32 D. 33

9. Answer A. 30 • 120 mL × 15 gtt/mL = 30 gtt/min 60 minutes

10. Determining Hours an IV Will Run • Number of milliliters ordered = Number of hours to run Number of milliliters per hour

11. Question How many hours will 500 mL of D5½NS run at 125 mL/hour? A. 3 B. 4 C. 5 D. 6

12. Answer B. 4 • Number of milliliters ordered = Number of hours to run Number of milliliters per hour • 500 mL = 4 hours 75 mL/hour

13. Choosing the Infusion Set • Microdrip • IV administered over a long period • Small amount of fluid to be infused • Macrodrops per minute too few • Macrodrip • Order specifies a large amount of fluid over a short time • Microdrips per minute are too many, and counting the drip rate becomes too difficult

14. Adding Medications to IVs • Check diluent and volume • Check dose and expiration date of reconstituted solution • Note whether IVPB should be refrigerated before use and remain at room temperature • Calculate the drip rate and record this information on IVPB label

15. Reconstitution Device

16. Enteral Nutrition • Used when patient cannot eat or cannot eat enough • Administered with a pump • Intermittent • Cyclic • Continuous
