A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors.

Systems, products, compounds and methods can be applied and/or used by a person to facilitate and promote the production of nitric oxide to be used by a person for health benefits. The systems, products, and devices include a nitric oxide nasal delivery system. The system can comprise one or more containers for compounds that when mixed are adapted to produce nitric oxide gas, at least one container with a nitrite compound and at least one container with an acid compound. Containers can be ruptured so that the compounds may be mixed and produce nitric oxide gas. The nitric oxide gas may then be delivered to a user via one or more of the nasal cavities and/or mouth.

A therapeutic gas source and cart and methods thereof for use with a therapeutic gas delivery system is disclosed. The therapeutic gas source may include a cylinder operable to contain a therapeutic gas that includes a body and a gas source valve body. In some examples, the gas source valve body has a valve and a coupling member.

A respiratory assistance apparatus includes a conduit connecting a flow generator and an outlet. The conduit includes a venture formation. The apparatus further includes an oxygen inlet in fluid communication or selective fluid communication with an oxygen outlet. The oxygen outlet is directed into the conduit and toward a mouth of the venture formation. The flow generator provides a flow path for air to enter the conduit when the flow generator is not operating.

There is provided a method of detecting a fault in a breathing system. The method comprises the steps of (a) taking a series of measurements of a first parameter of the breathing system; and (b) setting a fault boundary for the first parameter, the fault boundary being dependent on a plurality of the measurements of the first parameter. The method further includes at least one update procedure comprising the steps of (c) taking one or more further measurements of the first parameter; and (d) updating the fault boundary, the updated fault boundary being dependent on an updated set of measurements of the first parameter, the updated set of measurements of the first parameter including at least one of the further measurements of the first parameter.

A ventilation device for providing a gas mixture for a user including a compressor to output compressed air; a valve to receive the compressed air and medical gas and selectively output a gas flow of at least one of the medical gas and the compressed air; a patient interface configured to provide the output gas flow of the valve; and a controller to control the valve to deliver substantially only the medical gas to the patient interface during a first portion of the inspiratory period and deliver substantially only the compressed air to the patient interface during a second portion of the inspiratory period.

A device for improving cognitive and functional capabilities by means of hypoxic and hyperoxic gas mixtures. An air splitter (5) separates oxygen and nitrogen and feeds these gases to a mixer (4), whose mixing rate is determined by feed back from a bio feedback regulator and an oximeter. The oximeter is connected to a finger piece sensor or pulse meter, and/or an ear-piece sensor for receiving inpute from a patient. The gas mixer feeds an adjusted oxygen and nitrogen mixture to the patient by way of a mouthpiece connected to the mixer.
