Why is it important for a patient to perform the Valsalva maneuver when removing a short-term device?

• A. To facilitate catheter removal
• B. To reduce discomfort during removal
• C. To prevent an air embolism
• D. To promote faster healing

Answer: (C)

The importance of the Valsalva maneuver during the removal of a short-term central venous access device primarily lies in its role in preventing an air embolism. When a central venous catheter is withdrawn, there is a risk of air entering the vascular system, particularly if the pressure in the chest cavity changes abruptly. By performing the Valsalva maneuver, the patient increases intrathoracic pressure, which helps to occlude the veins and reduces the likelihood of ambient air being sucked into the bloodstream. This action creates a protective mechanism against the potentially life-threatening consequences of an air embolism, such as vascular obstruction and complications related to air bubbles traveling through the blood. Understanding this context highlights the significance of the Valsalva maneuver in clinical practice, ensuring the safety of the patient during the procedure.
