An IV bolus is a method of delivering a concentrated dose of medication or fluid directly into a vein over a short period of time, typically through an intravenous (IV) line.
This allows the substance to quickly enter the bloodstream and produce an immediate effect.
IV boluses are often used in medical situations where rapid administration of drugs or fluids is needed, such as to stabilize a patient experiencing shock, pain, or other acute conditions.
The bolus is typically given over a few minutes and is different from a continuous infusion, which delivers medication gradually over an extended period.
