In medical gas management, what is DISS used for?

DISS, or Diameter Index Safety System, is a critical component in medical gas management, specifically designed to prevent the incorrect connection of medical gas cylinders and pipeline systems. This system employs a unique diameter and threading pattern for each type of gas, which ensures that connections are only made with the appropriate gas type. The primary function of DISS is to enhance safety by reducing the potential for accidental mixing of gases—such as oxygen, nitrous oxide, and medical air—during gas delivery to patients.

In environments such as hospitals, where multiple gases are utilized, the DISS helps maintain a safe operating environment by ensuring that each gas supply is distinctly identifiable and cannot be inadvertently connected to equipment designed for another gas. This not only safeguards patient health but also supports adherence to regulatory standards for gas management in healthcare settings.
