While IV push delivers medication within seconds in emergencies and IV bolus takes minutes in less high-stakes situations, they both have something important in common. Both IV treatments deliver instantaneous results because they hit the bloodstream faster.
How do you give a bolus injection?

First, convert grams to milligrams: 2 g 2000 mg. Next, determine the concentration: 2000 mg per 500 ml = (2000/500) X (mg/ml) = 4 mg/ml. Since you’re using a 60 drop set, you multiply your VTBI by the drip factor. Then divide by the concentration of 4 mg/ml.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
