The Port Clearance Test: Why It Is Important to Clinicians

Understanding proper chamber flushing volume for each port manufacturer and port chamber shape is of value to both clinicians and patients. Failing to follow adequate flushing volumes may lead to sludge buildup and further complications. By sampling the chamber flushing volume of ports of various shapes from different manufacturers, we were able to assess cumulative volume flushing rates using a mixture approximating the viscosity of blood. The data collected highlight the relationship between chamber shape, flushing volume, and flow rate and why it is important that manufacturers recommend adequate flushing volumes specific to each port.
