Which component is used to distribute inflation media to multiple lines during PCI?

• A. Manifold
• B. Hemostatic valve
• C. Guide catheter
• D. Inflation device

Answer: (A)

When inflating balloons during PCI, you may need to feed inflation media to several lines from a single source. A manifold is designed to split that inflation media into multiple outputs, allowing you to connect multiple catheters or lumens and inflate them either simultaneously or independently while maintaining a closed, controlled flow. This makes it easier to manage several devices without swapping connections each time. The other components don’t perform that distribution function. A hemostatic valve sits at the catheter hub to prevent blood loss and air entry but doesn’t split the inflation media to multiple lines. The guide catheter is simply the access conduit into the coronary anatomy, not a distribution device. The inflation device provides the pressurized fluid to a single line (or to a line through adapters) and isn’t inherently a multiport distributor.
