Infusion Calculators
Calculate IV drip rates, infusion times, and protocol-based titrations.
Clinical Overview
Continuous IV infusions require precise calculations for rate, concentration, and dose delivery. These tools support rapid bedside calculations for gravity drips and infusion pumps.
Common Use Cases
- •Setting gravity drip rates (gtt/min)
- •Calculating total infusion time
- •Titrating protocol-based infusions (e.g., Heparin)
- •Converting between dose rate and pump rate
Clinical Pearls
Common Drip Factors
Microdrip tubing is always 60 gtt/mL. Macrodrip tubing varies by manufacturer but is typically 10, 15, or 20 gtt/mL.
Heparin Protocols
Most weight-based heparin protocols use actual body weight, but some institutions cap the weight for dosing at 100-120 kg to prevent supratherapeutic dosing in morbidly obese patients.
