Hyrum · Answer 1

The rate of infusion is 2.1L/19h or 2100mL/19h (as 1L = 100 mL).

To convert 19 hours to minutes we multiply as follows:

19 hours = (19 hours) x (60 minutes/1 hour) = 1140 minutes

So the rate of infusion becomes:

2100mL / 1140 min

In order to converted mL to drops (gtt) we multiply the rate of infusion with the drop factor to get the drip rate:

(2100mL/1140min) x (20 gtt/mL) = 36.8 gtt/min
