Abstract: The present disclosure provides to graphical user interfaces for controlling a flow therapy apparatus. The graphical user interface can provide a display of flow therapy treatment information and indicators of a patient's health. The graphical user interface can be configured to display the information associated with the patient on one or more user interface screens.

Abstract: A breathing assistance apparatus user interface is described which presents animated information related to the management of the apparatus. The user interface is provided on a display screen of the apparatus. The animated illustrations can correspond to operational modes, warnings, user instructions, fault conditions, status, menu options, and the like. The animations can include a sequence of images shown in rapid succession which depict moving icons or objects, scrolling text, flashing colors, or any combination of these or the like. The user interface can combine static information along with animations.

Abstract: The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.

Abstract: A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

Abstract: A breathing assistance system for delivering a stream of heated, humidified gases to a user, comprising a humidifier unit which holds and heats a volume of water, and which in use receives a flow of gases from a gases source via an inlet port, the flow of gases passing through the humidifier and exiting via an exit port, the system further having a temperature sensor which measures the temperature of the gases exiting the humidifier unit, an ambient temperature sensor which measures the temperature of gases before they enter the humidifier unit, and a flow sensor which measures the flow rate of the gases stream, the system also having a controller which receives data from the temperature and flow sensors, and which determines a control output in response, the control output adjusting the power to the humidifier unit to achieve a desired output at the humidifier unit exit port.

Abstract: An apparatus for delivering a flow of gas has a housing and a humidifier. The housing has a recess for a motor and/or sensor module, an outlet port for a flow of gas, and a removable elbow for a flow of gas. The humidifier has a heater, a chamber bay for receipt of a liquid chamber, and a lever and/or detent(s) for assisting with insertion and/or retention and/or removal of the liquid chamber in and/or from the chamber bay.
