摘要： Over-enthalpy conditions when using a respiratory and/or surgical humidifier system can be prevented. A heating element power in an inspiratory conduit can be limited based at least in part on one or more parameters of the gases flow, and/or on an ambient temperature. The limit on the heating element power in the inspiratory conduit can be achieved using a processor and/or protection circuit(s) located outside the processor. For example, the system can use the processor to determine and/or apply the limit as a level of protection and use the protection circuit(s) as another level of protection.

摘要： According to this disclosure there is provided a respiratory support apparatus configured to provide a gases flow to a patient, the respiratory support apparatus comprising: a flow generator configured to generate the gases flow; a humidifier configured to humidify the gases flow; and a controller. The apparatus is controlled by the controller to function in at least two modes, being a normal mode and a high-temperature mode. In the high-temperature mode the temperature of gases delivered to the patient is higher than the temperature of gases delivered to the patient when in the normal mode. In the high-temperature mode, the controller controls one or more parameters of the gases flow to be different to that in the normal mode, whilst providing higher temperatures. The apparatus is also operative in a cool-down mode in which one or more parameters of the gases flow are controlled. The apparatus includes safety features to ensure the temperature, dew-point, enthalpy, and/or energy of the gases flow do not exceed safe limits.

摘要： A method for delivering a substance into an airway of a user via a respiratory system comprises receiving the substance within a receptacle; receiving physiological data; determining one or more sleep-related parameters based on the physiological data; and modifying the delivery of the substance into the airway of the user based at least in part on the one or more sleep-related parameters. The respiratory system includes a respiratory device configured to supply pressurized air to the airway of the user via a conduit and a user interface. The respiratory device, the user interface, and the conduit form an air pathway. The respiratory device is configured to include or engage the receptacle such that an outlet of the receptacle is in direct or indirect fluid communication with the air pathway.

摘要： An apparatus (100) for humidifying a gas flow stream (110) is described. The apparatus comprises a plurality of humidification chambers (114, 116) connected in a sequence to allow the gas flow stream to flow sequentially through the plurality of humidification chambers. Each humidification chamber is configured to contain a liquid (124) over which the gas flow stream can flow. At least one humidification chamber comprises a nozzle (118) that forms the gas flow stream into a gas jet (120) that impinges on a surface (122) of the liquid (124) in each humidification chamber. The humidity level of the gas increases as the gas flow stream flows sequentially through the plurality of humidification chambers.
