IV Drip Rate Calculator 💧

Accurately determine the **IV Fluid Flow Rate** (mL/hr) and **Drip Rate** (drops/min or gtts/min) for gravitational infusions.

1. Enter Infusion Parameters

Total Volume to Infuse (mL)

The total **mL** in the **IV** bag.

Infusion Time (Hours)

Use decimals for minutes (e.g., 1.5 for 90 min).

Drop Factor (gtts/mL)

Found on the **IV** tubing packaging.

mL/hour

drops/minute (gtts/min)

⚠️ **ALWAYS** double-check manual drip rate against the **IV** pump setting or a second clinician for patient safety.

Two main calculations are required for **IV** administration:

Calculates the required rate in **mL** per hour.

Flow Rate (mL/hr) = Total Volume (mL) / Time (hours)

Calculates the required drops per minute, crucial for manual administration.

Drip Rate (drops/min) = (Total Volume (mL) x Drop Factor (gtts/mL)) / Time (minutes)
