Gtts Per Minute Calculator

Formula

The formula to calculate the Gtts Per Minute (GPM) is:

\[ GPM = \frac{V \cdot DF}{T} \]

Where:

\( GPM \) is the Gtts per minute.
\( V \) is the volume in milliliters (ml).
\( DF \) is the drop factor (gtts/ml).
\( T \) is the time in minutes (min).

What is Gtts Per Minute?

Gtts per minute, also known as drops per minute, is a measurement used in medical treatments, particularly in intravenous therapy, to calculate the drip rate of intravenous fluids or medication. It is crucial in ensuring the patient receives the correct dosage over the appropriate period. The calculation takes into account the volume of fluid, the time over which it should be administered, and the drop factor of the specific IV tubing.

Example Calculation

Consider an example where:

Volume (V): 500 ml
Drop Factor (DF): 20 gtts/ml
Time (T): 60 min

Using the formula to calculate the Gtts Per Minute:

\[ GPM = \frac{500 \cdot 20}{60} \approx 166.67 \text{ gtts/min} \]

This means that the Gtts per minute for this example is approximately 166.67 gtts/min.
