The physician orders, "One liter of D5 1/2 Normal Saline to infuse in 8 hours. The drop factor of the IV tubing is 15 gtt/ml. What is the flow rate (ml/hr)?
To calculate just the ML /hour of infusion is
Total volume in ml divided by the total time in hours is equal to ml per hour.
Given solution is D51/2 normal saline one liter
Time given is 8 hours
One liter=1000ml
So the total ml per hour is
1000/8=125ml/hour
Answer is 125ml/hour
To calculate gtts / min according to drop factor 15 gtts/ml
Total volume divided by total hour ×60 multiply with drop factor
125/1×60=2.08
2.08 multiply with iv drop factor
2.08×15= 31.2 gtts/min.
