A Ballard/closed suction system comprises which components?

• A. Catheter and valve
• B. Catheter, sheath, and valve
• C. Catheter, tubing, and suction bottle
• D. Valve and cannula

Answer: (B)

A closed suction system is a self-contained unit designed to maintain a sterile, closed path for suctioning without disconnecting the ventilator circuit. The essential parts are the suction catheter, a protective sheath that surrounds the catheter to keep the channel closed and sterile, and a valve that seals the system when suction isn’t being applied. This combination lets you perform suctioning while preserving the integrity of the airway circuit and preventing contamination. Other external elements like tubing or collection bottles are part of the overall suction setup but do not define the Ballard closed suction assembly.
