Question: how to do iv piggyback calculations?
Answer: Let's look at an example of an IV piggyback medication… You have macrodrip tubing with a drop factor of 10 gtts/mL. Calculate how many gtts/min to set as the IV flow rate. Use the formula, with 100 mL divided by 30 min, multiplied by 10 gtts/min, which equals 33.3, rounded to 33 gtts/min.
