A therapeutic gas delivery system with at least one gas supply subsystem is disclosed. The at least one gas supply subsystem may include a gas source coupling configured to receive a therapeutic gas source and form a fluid flow connection with the therapeutic gas source, a therapeutic gas delivery system controller, and one or more display(s) configured to be in communication over a communication path with the therapeutic gas delivery system controller. The display may be configured to display a graphical, illustrative, or numerical indicator of one or more flow or system parameters.

Systems and methods are provided for intraoperative real-time clinical decision support. A system includes a processor, a non-transitory computer readable medium, storing executable instructions, and an output device. An interface is configured to receive a first set of patient data in real-time from at least one sensor monitoring vital signals of a patient during a surgical procedure and a second set of patient data in real-time from an anesthesia machine during the surgical procedure. An input interface receives an indicator representing at least an identity of a therapeutic to be administered to the patient. A machine learning model determines from the indicator, the first set of patient data, and the second set of patient data if an alert should be provided to a user. The output device provides the alert to the user if the machine learning model determines that the alert should be provided.

Some embodiments of an inhalation exposure system can deliver a gas, such as an aerosol, through a manifold to a set of exposure chambers in a controlled manner so as to achieve improved consistency for all of the test subjects.

Various systems, devices, NO.sub.2 absorbents, NO.sub.2 scavengers and NO.sub.2 recuperator for generating nitric oxide are disclosed herein. According to one embodiment, an apparatus for converting nitrogen dioxide to nitric oxide can include a receptacle including an inlet, an outlet, a surface-active material coated with an aqueous solution of ascorbic acid and an absorbent wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the surface-active material and the absorbent such that nitrogen dioxide in the gas flow is converted to nitric oxide.

A lighted air supply delivery assembly for use in delivering air to a patient is described herein. The lighted air supply delivery assembly includes an air/light connection tubing coupled between an oxygen concentrator and a patient oxygen delivery. The air/light connection tubing defines an airflow chamber for delivering a flow of oxygenated air from the oxygen concentrator to the patient oxygen delivery assembly, and includes one or more optical fibers positioned within the airflow chamber. A fiber-optic light engine coupled to the one or more optical fibers. A controller is coupled to the fiber-optic light engine and includes a processor programmed to execute algorithm steps of operating the fiber-optic light engine to display a light visible through the air/light connection tubing via the one or more optical fibers.

For the production of an assembly for a patient ventilation system, at least one conducting connection is first prepared between contact pins of a component receptacle of a connector for the insertion of at least one electronic component and sheath wires which are guided along a tube sheath of a breathing air tube portion of the assembly. This prepared conducting connection is overmolded to form an inner conduction carrier housing sleeve of the connector. The conducting connection is connected to the sheath wires and the inner conduction carrier housing sleeve is overmolded to form an outer connector housing of the connector in which the component receptacle is implemented. This results in an assembly manufacturing process that is suitable for mass production.

An assembly for a patient ventilation system has a respiratory air hose section for guiding ventilation air from a ventilation source to a patient. A connector, connected to the respiratory air hose section, is used to connect the respiratory air hose section to a further component of the patient ventilation system guiding ventilation air. An air guiding connector component of the connector forms an integral component with the respiratory air hose section. The connector has a sensor receptacle for inserting a temperature sensor into the air guiding connector component. The temperature sensor is used to measure a temperature of the ventilation air. A temperature sensor device to be plugged into the sensor receptacle of the assembly has a support body, the temperature sensor protruding beyond the support body, and a handle section to grasp a section of the support body facing away from the temperature sensor.

Various embodiments are described herein for a controller for controlling the operation of a breathing assistance device that provides breathing assistance to a user. The controller comprises a processor that generates a respiratory index value that is determined during a current monitoring time period to detect a respiratory failure, or predict the respiratory failure when at least one PSG signal is measured. The respiratory index value is compared to a threshold to determine if the control signal needs to be updated to reduce or eliminate respiratory failure that the user is currently experiencing or to prevent a predicted respiratory failure from occurring.

In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.

A vapour generating device includes an oven arranged to receive a substrate to be vapourized, an inlet, an outlet, an airflow passageway for providing a fluid connection between the inlet and the outlet via the oven through which generated vapour can flow from the oven to the outlet. A device controller and a humidity sensor for generating a measurement of a vapour produced by the substrate are provided. The controller is operable to control the operation of the device based on measurement data from the humidity sensor.
