Answer to Question #16106 in Physical Chemistry for Beverly

Question

10. You have received an order for 3 L of 0.9% NaCl to be infused by an infusion set rated at 60 gtt/mL set at 60 gtt/min. How long will it take to infuse the 3 L of fluid?

Answer 1

3 L of fluid = 3000 mL
The formula for drops per minute is:

volume
to be infused x drip factor

------------------------------------------------
time in
minutes

Thus, 60 gtt/min = (3000 mL * 60 gtt/mL) / t
t = (3000 mL * 60
gtt/mL) / 60 gtt/min = 3000 min = 50 hrs
