For IV piggyback problems, use the standard calculation formula used for IVs: Milliliters F1F1F1S1?F1F1F10 TF/Minutes = gtt/minute. Therefore, 50 mL F1F1F1S1?F1F1F10 15 gtt/mL ÷ 30 minutes = 750/30 = 25 gtt/minute. You can also use the dimensional analysis formula: gtt/mL F1F1F1S1?F1F1F10 Total mL/Minutes: 15 gtt/1 mL F1F1F1S1?F1F1F10 50 mL/30 minutes; 15 gtt F1F1F1S1?F1F1F10 50/1 F1F1F1S1?F1F1F10 30 minutes = 750 gtt/30 minutes = 25 gtt/minute.
