Registry build 21.09.26

The PRO NOX Relieve Nitrous Oxide/Oxygen Analgesic Gas Mixing and Delivery System is a portable pneumatically powered device designed to provide a 50/50% nitrous oxide and oxygen mixture. It provides two input connectors for connection with nitrous oxide and oxygen cylinders through pressure regulators. The device has only one control for turning ON or OFF the device. When it is turned ON, the output of N2O/O2 gas mixture will only be activated by an inspiratory effort by the patient. The out put of N2O/O2 gas mixture is pre-set at 50/50%. Neither the patient nor medical personnel are able to adjust, eliminating the risk of delivering a hypoxic mixture.
