What is the function of the injection port in IV tubing?

The injection port in IV tubing serves the crucial function of allowing healthcare providers to introduce medications or fluids into the intravenous line without compromising the sterile environment. This is vital in maintaining the integrity of the IV system and preventing contamination that could occur if the line were opened to the outside environment. By using the injection port, providers can ensure that the medication is infused in a controlled manner while keeping the flow of the primary IV solution uninterrupted. This mechanism enhances patient safety and ensures that necessary medications can be delivered effectively.

In contrast, while air bubbles can become problematic in IV lines, the injection port is not designed specifically for their release; other methods are used to address that issue. Additionally, although connecting multiple IV lines is important in certain scenarios, that is handled through specific connectors and not through the injection port. Lastly, monitoring pressure in the IV system is typically accomplished through gauges or sensors rather than the injection port.
