What is the role of flushing in maintaining a CVAD?

• A. To provide medication through the catheter
• B. To clear occlusions and maintain catheter patency
• C. To measure blood flow
• D. To reduce insertion site pain

Answer: (B)

Flushing is an essential practice in maintaining a Central Venous Access Device (CVAD) and plays a crucial role in ensuring that the catheter remains patent. The primary purpose of flushing is to clear any potential occlusions that could arise from blood clotting or the buildup of medication residues within the catheter. By instilling a solution, usually saline, the healthcare professional ensures that blood flow remains unobstructed, which is vital for the effective delivery of medications and the withdrawal of blood samples.

Maintaining catheter patency is critical, as occlusions could lead to blockages that compromise treatment efficacy and may necessitate more invasive interventions to restore function. Therefore, the role of flushing directly correlates to the prevention of complications that can arise from catheter use, promoting patient safety and treatment success.
