What is a "push-pause" technique in CVAD flushing designed to accomplish?

• A. To create turbulence and clear the line
• B. To ensure the line is permanently blocked
• C. To increase catheter size for better flow
• D. To minimize saline usage during flushing

Answer: (A)

The "push-pause" technique in flushing a Central Venous Access Device (CVAD) is specifically designed to create turbulence within the catheter and clear it of any potential debris or clogs. This method involves alternating between pushing saline into the catheter and pausing briefly, which allows for the fluid to create a dynamic flow pattern that effectively dislodges any accumulated particles or residual medications along the catheter walls. This technique is especially important in maintaining patency of the CVAD and ensuring that it functions properly for administration of therapies. Utilizing this technique enhances fluid movement through the catheter and promotes better cleaning than steady-state flushing would achieve. The turbulence generated aids in preventing complications such as occlusion, which can lead to thrombus formation or infection if not effectively managed.
