850 ml is to be administered to a person over 8 hours using a drop factor of 20 drops/ml what is the flow rate in gtts/min?
(vol mL/time min)]*drop factor = flow rate.
[(850/8*60)]*20 = flow rate
To determine the flow rate in gtt/min (drops per minute), you need to follow these steps:
Step 1: Calculate the total number of drops needed.
Total drops = Volume (ml) x Drop factor
In this case, the volume is 850 ml, and the drop factor is 20 drops/ml.
Total drops = 850 ml x 20 drops/ml
Total drops = 17,000 drops
Step 2: Calculate the total time in minutes.
The total time is given as 8 hours. Since 1 hour = 60 minutes, the total time in minutes is:
Total time = 8 hours x 60 minutes/hour
Total time = 480 minutes
Step 3: Determine the flow rate in gtt/min.
Flow rate (gtt/min) = Total drops / Total time
Flow rate = 17,000 drops / 480 minutes
Flow rate ≈ 35.42 gtt/min (rounded to two decimal places)
Therefore, the flow rate in gtt/min is approximately 35.42 gtt/min.
