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.

Systems and methods for nitric oxide (NO) generation systems are provided. In some embodiments, an NO generation system comprises at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas. The electrodes have elongated surfaces such that a plasma produced is carried by the flow of the reactant gas and glides along the elongated surfaces from a first end towards a second end of the electrode pair. A controller is configured to regulate the amount of NO in the product gas by the at least one pair of electrodes using one or more parameters as an input to the controller. The one or more parameters include information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which the product gas flows.

A mechanical insufflation-exsufflation device including an air source to provide positive airway pressure (PAP); a patient interface; at least one sensor to sense air pressure and flow at the patient interface; and a controller to control the air source to deliver at least one mechanically assisted cough to the patient in response to at least one of a target breathing flow and a target inhalation time period being sensed by the at least one sensor, and when the at least one of a target breathing flow and a target inhalation time period is not sensed, the controller is configured to control the air source to deliver each in a series of high-level PAP provided over a duration being followed by a low-level PAP provided over a duration, the series of high-level PAP increasing in pressure level and duration from a prior one in the series of high-level PAP.

A CPAP device for delivering pressurized, humidified breathable gas for a patient includes a flow generator configured to pressurize a flow of breathable gas. The flow generator includes an air outlet and a removable water container configured to humidify the pressurized breathable gas received from the flow generator. The water container includes an air inlet and an air outlet. The CPAP device further includes a first elastomeric face seal configured to sealingly abut against a substantially flat portion of the water container surrounding the water container air inlet, the first elastomeric face seal being located at an intermediate position between the flow generator air outlet and the water container air inlet when the water container is placed into position to pneumatically communicate with the flow generator. In addition, the CPAP device includes a second elastomeric face seal, a portion of which is configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.

A communication system for operation of respiratory pressure therapy devices for treating respiratory disorders of a plurality of patients includes one or more servers configured to communicate with the plurality of respiratory pressure therapy devices. The server(s) are configured to receive communications relating to respiratory therapy delivered to a patient via at least one respiratory pressure therapy device of the plurality of respiratory pressure therapy devices. The server(s) are configured to transmit one or more responsive communications for control of the at least one respiratory pressure device according to a selected action to improve the respiratory therapy. The selected action includes transmitting, from the server(s), a control command to the at least one respiratory pressure therapy device. The responsive communication(s) are generated in response to a compliance prediction that is a score indicating a probability that the patient will be compliant with a predetermined compliance rule.

Apparatus for treating a respiratory disorder in a patient comprises a pressure generator configured to deliver a flow of air at positive pressure to an airway of the patient through a patient interface, a sensor configured to generate a respiratory flow rate signal of the patient, and a controller. The controller may be configured to control the generator to deliver ventilation therapy having a base pressure and a pressure support through the patient interface, detect an apnea from the signal representative of respiratory flow rate of the patient, control the generator to deliver one or more probe breaths to the patient during the apnea, determine patency of the patient's airway from a waveform of the respiratory flow rate signal in response to one of the one or more probe breaths and adjust a set point for pressure of the ventilation therapy in response to the apnea.

Modular ventilatory support systems and methods are disclosed in which a user may transition the system between a stationary configuration, an extended range configuration, and a stand-alone configuration. The modular components of the system include a compressor unit, a ventilator which may dock with the compressor unit, and a patient interface which may be connected to either the compressor unit or the ventilator unit. By rearranging these modular components into different configurations, mobility and duration of use may be optimized to fit the present needs. In the stationary configuration, mobility is most restricted, but duration of use is maximized. In the extended range configuration, mobility is enhanced, with duration of use limited by the battery power of the ventilator. In the stand-alone configuration, mobility is maximized, with duration of use limited by battery power of the ventilator and the quantity of an external gas supply.

A breathing mask comprises a mask body, a mask bead, at least one mask wing, and at least one filter element. The mask bead is connected to the mask body, and the mask wing is connected to the mask body and/or the mask bead. The mask bead is formed at least in sections for contact on the skin of a user and presses against the skin of the user during use of the breathing mask in such a way that the breathing mask terminates essentially respiratory gas-tight. The mask bead includes a receptacle opening, which is configured to receive at least nose and mouth of the user during use of the breathing mask. The filter element is connected to the mask wing and is configured in such a way that respiratory gas can flow through it at least in some areas.

A filler device includes a distal housing comprising a distal inner port and a distal outer port; a proximal housing comprising a proximal inner port and a proximal outer port, the proximal housing being sealingly affixed to the distal housing to form an inspiratory pathway between the distal inner port and the proximal inner port and to form an expiratory pathway between the distal outer port and the proximal outer port that is fluidly sealed from the inspiratory pathway, the inspiratory pathway being laterally adjacent the expiratory pathway; and a first filter in the inspiratory pathway or in the expiratory pathway to filter gases flowing through the inspiratory pathway or the expiratory pathway.
