What technique is recommended for flushing a CVAD to reduce the risk of clot formation?

• A. Continuous flush technique
• B. Gravity flush technique
• C. Push-pause technique
• D. Slow drip technique

Answer: (C)

The push-pause technique is recommended for flushing a CVAD to minimize the risk of clot formation due to its effective method of clearing the lumen of the device. This technique involves alternating between a rapid push of the flushing solution and brief pauses, creating turbulence within the catheter and preventing blood from stagnating. The turbulence helps to dislodge and break up any potential clots that may form within the catheter, ensuring that the lumen is properly cleared and reducing the risk of occlusion. This method is particularly advantageous in maintaining patency in CVADs as it ensures a thorough flush, preventing blood from pooling at the distal end of the catheter where clots are more likely to develop. It also allows for the administration of medications through the CVAD while ensuring that the line remains patent. In contrast, other techniques such as the continuous flush may not be as effective in achieving this level of clearance, as they do not incorporate the intermittent pressure application that enhances flow dynamics.
