Overview

Explanation

Normal Saline is to be infused. You would need to know how much volume you needed in order to solve. The volume is 1200 ml over 6 hour. The hour is converted to minutes by taking the 6 hours and multiplying by 60. The total minutes is set at 360. There is a simple formula below for calculating the drop factor. The final answer should have gtt/min within.

ML

—– x gtt

Min

1200 mL/360 min (6 hr x 60 min) x 15 gtt factor/1 = 50 gtt/min
