GTTS Per Minute Calculator

The GTTS (drops per minute) calculator is a valuable tool used primarily in healthcare, particularly for intravenous (IV) fluid administration. By considering the volume of fluid, the time over which it should be delivered, and the drop factor (typically specific to the IV tubing), the calculator determines the drip rate in drops per minute (gtts/min), ensuring accurate dosage and patient safety.

Formula

The calculation formula is:

\[ \text{GTTS per minute} = \frac{\text{Volume (mL)} \times \text{Drop Factor (gtts/mL)}}{\text{Time (minutes)}} \]

Example Calculation

If you need to deliver 500 mL over 120 minutes using tubing with a drop factor of 15 gtts/mL:

\[ \text{GTTS per minute} = \frac{500 \times 15}{120} = 62.5 \text{ gtts/min} \]

This calculator is essential in clinical settings to ensure accurate IV administration.
