What is IV bolus and IV infusion?
This is the medical term for a dose of a particular substance, such as a medication. Technically, all IV treatments use a bolus of vitamins, nutrients or medications. But an IV bolus is a particular type of therapy. Unlike a standard drip IV where the fluid line is closed, an IV bolus has an open line.
What is meant by bolus infusion?
The injection of drug in a single large volume (a bolus), as in an IV infusion, in contrast to gradual administration.
Why IV infusion is preferred over IV bolus?
For some drugs, IV bolus injections can result in immediate high plasma drug concentrations and drug toxicity. An IV drug infusion slowly inputs the drug into the circulation and can provide stable drug concentrations in the plasma for extended time periods.
What is a bolus IV used for?
A bolus delivered directly to the veins through an intravenous drip allows a much faster delivery which quickly raises the concentration of the substance in the blood to an effective level. This is typically done at the beginning of a treatment or after a removal of medicine from blood (e.g. through dialysis).
What is bolus function?

Which is better IV or IM?
IV drug administration achieves high plasma concentrations rapidly in plasma and tissues. Muscles are very vascular structures, and IM absorption occurs by drug diffusion from interstitial fluid and capillary membranes into plasma, and so onset of action is longer than IV injection.
What is bolus in IV therapy session?
ENROLLED. The administration of a bolus dose of intravenous medication is the administration of the prepared medication directly into the bung of a cannula placed into the vein of the person.
