To calculate GTT mL, you need to know the mL/hr (milliliters per hour) and the drop factor. The drop factor is the number of drops in one milliliter of fluid. The formula to calculate GTT mL is mL/hr multiplied by the drop factor, divided by 60 (minutes in an hour).
Let’s say you have a patient who needs an IV infusion at a rate of 130 mL/hr, and the drop factor is 20 gtt/ml. To calculate the GTT mL, you would multiply 130 mL/hr by 20 gtt/ml, which equals 2600. Then, you divide 2600 by 60 (minutes in an hour) to get the GTT mL per minute.
So, in this case, the GTT mL would be 2600/60, which equals 43 gtt/min.
It’s important to note that the drop factor may vary depending on the type of IV administration set being used. Common drop factors range from 10 to 60 gtt/ml. It’s crucial to always check the drop factor specified on the IV administration set to ensure accurate calculations.
Calculating GTT mL is essential in healthcare settings to determine the appropriate flow rate for IV infusions. It ensures that the medication or fluid is being administered at the prescribed rate, allowing for proper hydration or medication delivery to the patient.
In my personal experience as a healthcare professional, I have used this calculation numerous times when setting up IV infusions for patients. It’s crucial to double-check all the values, including the mL/hr and drop factor, to prevent errors and ensure patient safety.
