Abstract: A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

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.
