Calculation Formulas
Drops per Minute: (Volume × Drop Factor) ÷ (Time × 60)
mL per Hour: Volume ÷ Time
mL per Minute: (Volume ÷ Time) ÷ 60
Drop Interval: 60 ÷ Drops per Minute
Where:
• Volume = Total volume in mL
• Drop Factor = gtt/mL (varies by tubing)
• Time = Infusion time in hours
• 60 = Conversion factor (minutes per hour)
mL per Hour: Volume ÷ Time
mL per Minute: (Volume ÷ Time) ÷ 60
Drop Interval: 60 ÷ Drops per Minute
Where:
• Volume = Total volume in mL
• Drop Factor = gtt/mL (varies by tubing)
• Time = Infusion time in hours
• 60 = Conversion factor (minutes per hour)
Drop Factor Guide
| Tubing Type | Drop Factor | Common Use | Flow Characteristics |
|---|---|---|---|
| Macrodrip | 10-20 gtt/mL | Standard adult infusions | Faster flow, easier counting |
| Microdrip | 60 gtt/mL | Pediatric, critical care | Precise control, slower flow |
| Blood tubing | 10 gtt/mL | Blood transfusions | Prevents hemolysis |
| Pediatric | 60 gtt/mL | Neonatal, pediatric | Ultra-precise control |
