An IV bolus is a method of intravenous therapy that delivers a concentrated dose of medication or fluid directly into a vein.
- It refers to a single dose of medication given over a short period.
- It is quicker than an IV drip but slower than an IV push.
An IV bolus can be used in critical situations where rapid treatment is necessary for non-emergency purposes, such as pain management or rehydration.
