Where is the DISS typically used?

The DISS, or Diameter Index Safety System, is specifically designed to prevent the inadvertent connection of gas cylinders to the wrong equipment by using unique fittings for different gases. This system is commonly used on walls behind patient beds because it allows for the safe and proper delivery of medical gases, such as oxygen, nitrous oxide, and others, directly to patients. The DISS fittings are installed in situations where gases need to be connected to flow meters, regulators, or other equipment, ensuring that only the correct gas can be connected to each outlet.

This context is crucial in clinical settings where the risk of error must be minimized, and the health and safety of patients depend on the correct administration of medical gases. Thus, the use of DISS in such locations is vital for providing safe patient care.
