What should be performed if a patient is able during the removal of a CVAD?

The Valsalva maneuver is recommended during the removal of a central venous access device (CVAD) because it helps to prevent air from entering the bloodstream, a condition known as air embolism. When the patient is able to perform this maneuver, they are instructed to take a deep breath and bear down as if having a bowel movement, which increases intrathoracic pressure and can reduce the risk of air being drawn into the vascular system.

This technique is particularly useful during the crucial moment when the catheter is being removed, as it helps create a barrier to air entry. The patient’s active participation in this process is important and can enhance safety.

In contrast, while deep breathing exercises can be beneficial in various situations, they do not specifically address the risk of air embolism during the removal of a CVAD. Remaining silent during the procedure is neither required nor beneficial, as communication may be necessary for the healthcare team to ensure the patient's safety and comfort. Talking to staff, while it can serve as a means of distraction or coordination, does not offer the same protective mechanism against air embolism as the Valsalva maneuver does.
