Diameter Index Safety System



A set of engineering standards preventing users of compressed gases from linking pressurized gas holding tanks to the wrong hoses or tubing. The standards designate specific-sized connectors for each different medical gas. The system is designed to prevent delivering room air or nitrogen to a patient in need of oxygen therapy.


Whenever gases, e.g., anesthetics, nebulized medications, or oxygen, are administered to patients, the identity of the source gas, and the required flow rates or concentrations should be verified and monitored.
