Study Notes
IV Flow Rate Calculations
-
For a prescription of 1,500 mL of normal saline over 7 hours:
- Flow rate: 214 mL/hour
- Drops per minute: 54 drops/minute
- Calculation: 1,500 mL ÷ 7 hours = 214.3 mL/hour; 1,500 mL ÷ 420 minutes = 3.57 mL/min x 15 drops/mL = 53.55 drops/minute
-
For a prescription of 1,200 mL of 0.45% normal saline at 125 mL/hour:
- Drops per minute: 25 drops/minute
- Calculation: Infusion time: 1,200 mL ÷ 125 mL/hour = 9.6 hours; 9.6 hours x 60 = 576 minutes; Total drops: 1,200 mL x 12 drops/mL = 14,400 drops ÷ 576 minutes = 25 drops/minute
-
For a patient receiving 250 mL of D5W over 2 hours and 45 minutes:
- Drops per minute: 91 drops/minute
- mL per hour: 91 mL/hour
- Total infusion time in minutes: 165 minutes (2 hours = 120 minutes, plus 45 minutes); Total drops: 250 mL x 60 drops/mL = 15,000 drops ÷ 165 minutes = 90.90 drops/minute
- Time duration: 2 hours and 45 minutes added to 15:00 starts at 17:45
-
For a prescription of 250 mL of platelets over 2 hours and 30 minutes:
- Flow rate: 100 mL/hour
- Drops per minute: 17 drops/minute
- Total infusion time in hours: 2.5 hours; Calculation: 250 mL ÷ 2.5 hours = 100 mL/hour
- Total infusion time in minutes: 150 minutes; 250 mL ÷ 150 minutes = 1.66 mL/minute; Total drops: 1.66 mL/min x 10 drops/mL = 16.66 drops/minute, rounded to 17 drops/minute
-
For a prescription of 1.25 liters of D5LRS over 18 hours:
- Calculation pending for flow rate in mL/hour.
- Drop factor: 20 drops/mL will be used for further calculations.
