If a physician orders 1000 mL of a medicine through an IV and it delivers the medicine at 75 ml/hr and the drop factor is 15 gtt/ml (15 drops per mL). Calculate the flow rate.


Solutions

Expert Solution

Use the formula

IV flow rate (gtt/min) = Volume (ml)/time(hr) * drop factor (gtt/ml)

In the current case, volume/time = 75 ml/hr (given rate) and drop factor = 15 gtt/ml

Thus, the IV flow rate (gtt/min) = 75 ml/hr * 15 gtt/ml = 1125 gtt/hr

Using the fact that 1 hr = 60 min

Flow rate (gtt/min) = 1125/60 gtt/min = 18.75 gtt/min.
