What is a fluid bolus?

A fluid bolus is a technique used in medical settings to rapidly administer large amounts of fluid intravenously. This is typically done in emergency situations where a patient is severely dehydrated or has suffered significant blood loss. The fluid bolus is administered over a short period of time, usually 10 to 20 minutes, and can consist of saline solution, dextrose, or other intravenous fluids. The exact amount of fluid administered will vary depending on the patient and the situation, but can range from 500 milliliters to several liters. The fluid bolus is closely monitored to ensure that the patient's vital signs remain stable and there are no adverse reactions to the fluids being administered.
