Which system is associated with pipeline supply and which is associated with cylinders?

• A. PISS for pipeline, KISS for cylinders
• B. KISS for pipeline, PISS for cylinders
• C. DISS for cylinders, PISS for pipeline
• D. PISS for both

Answer: (B)

The correct answer indicates that the KISS system is associated with pipeline supply, while the PISS system is related to cylinders.

The KISS (Keep It Simple and Safe) system is designed specifically for the connection of medical gas pipelines to anesthesia machines. It ensures that each type of gas pipeline has a unique connection point, which helps to prevent the incorrect connection of different gases, thus ensuring patient safety in the operating room.

On the other hand, the PISS (Pin Index Safety System) is used for oxygen and nitrous oxide cylinders. This system utilizes a specific arrangement of pins and holes that allows only the correct gas cylinder to be connected to the corresponding yoke on the anesthesia machine. This prevents the exchange of gases that could lead to dangerous clinical situations.

This distinction reinforces how safety measures are built into the systems for both pipeline and cylinder gas supplies, minimizing the risk of errors during anesthesia delivery.
