Abstract
A system and method for reducing the risk of fire in an oxygen delivery system. The system may include an oxygen delivery device with a controller in communication with a flow control valve to control a flow of oxygen through a tubing from an oxygen source to a patient interface. The controller may be programmed to close the flow control valve for a predetermined time period at a predetermined time interval to cause a periodic oxygen pause, the periodic oxygen pause to remove oxygen that may serve as an oxidizer when a fire is present inside at least one of the patient interface and the tubing.
