Why should a tourniquet be avoided on a CVAD?

• A. It enhances catheter visibility
• B. It increases the risk of clot formation
• C. It causes immediate dislodgement
• D. It simplifies the flushing process

Answer: (B)

A tourniquet should be avoided on a Central Venous Access Device (CVAD) primarily because it increases the risk of clot formation. When a tourniquet is applied, it restricts blood flow to the area, which can lead to stasis—a condition where blood flow is slowed or halted. This stasis can encourage the formation of clots in and around the catheter, potentially leading to complications such as thrombosis or occlusion of the CVAD. In managing CVADs, it is crucial to maintain adequate blood flow and minimize the risk of clots to ensure the device functions properly and patient safety is upheld. Understanding this principle helps healthcare professionals apply appropriate practices during central venous access and maintenance.
