What is the primary purpose of using a pressure bag in IV therapy?

The primary purpose of using a pressure bag in IV therapy is to administer fluids rapidly or in emergencies. A pressure bag helps deliver intravenous fluids at a higher pressure than the usual gravity flow method, ensuring that fluids can be infused quickly when a patient needs immediate treatment, such as in cases of shock, trauma, or severe dehydration.

The use of a pressure bag effectively increases the flow rate of fluids, allowing healthcare providers to manage critical situations where time is of the essence. This capability is crucial when rapid fluid resuscitation is necessary to stabilize a patient's condition.
