Infusion rates as above should be administered with either a Dial-A-Flow or infusion pump. The type of administration set does not matter.
Example: Administer a dopamine infusion to an 80kg (176lbs) individual using the standard dopamine concentration of 1600mg/mL at a rate of 5mg/kg/min. You should prepare this drip by adding 800mg of dopamine to a 500mL bag of 0.9% saline solution (normal saline). What rate should you set your Dial-A-Flow if you are using a 10gtt/mL administration set.
Answer: According to the chart the answer is 15.0mL/hr
Proof:
Step 1:
Calculating gtt/min
gtt/min =
(5mg/kg/min)(80kg)(500mL)(10gtt/mL)
= 2.5gtt/min
800,000
mg
Step 2:
Convert gtt/min into mL/hr
m/hr = (2.5gtt/min)(60min/1hr) = 15mL/hr Like
Magic, It Works!
