I am having a hard time figuring out how to calculate a continuous infusion. I know how to calculate an intermittent infusion but am having a serious brain block about the continuous. I have an exam tomorrow. Can someone help me with an example?? Thanks!:bowingpur

Continuous infusion, I think, is total volume in mL divided by total time to be infused in hours.
For example, order: 1000mL NS to be infused over 24 hours = 41.6 = you would set the infusion pump at 42mL/hour
Hope this was helpful.

Can you give me an example of a calculation you are having difficulty with?
Example 1 - Saline lock Example 2 - Continuous IV
Primary rate 120 ml/hr Primary rate Example 2 is the same medication but is
D5-1/2 NS running at 75 ml/hr.
Primary VTBI 20 ml Primary VTBI
Secondary rate 20 ml/hr Secondary rate
Secondary VTBI 60 ml SecondaryVTBI
Order: Ceftriaxone 1 gm IV q 12 hours. Dilute in 50 ml D5W and infuse over 30 minutes.
Supplied: Ceftriaxone 1 gm powder in a vial. Reconstitute with 9.6 ml. sterile water for a final concentration of 100mg/ml for a final volume of 10 ml.

Okay, so what specifically are you having trouble with in this problem?
