- Example: Calculate the IV flow rate for 1200 mL of NS to be infused in 6 hours. The infusion set is calibrated for a drop factor of 15 gtts/mL.
- (Volume (mL) / Time (min)) x Drop Factor (gtts/mL) = Y (Flow Rate in gtts/min)
- Convert 6 hours to minutes. - min ← hr ( x by 60 ) - 6 hr x 60 = 360 min (1200 mL / 360 min) x 15 gtts/mL = 50 gtts/min
