摘要： Apparatus and methods provide operations for a respiratory disorder therapy by generating a flow or pressure therapy with supplementary oxygen. The method may be implemented by one or more processors that may set one or more therapy parameters associated with generating a flow of air to a patient interface via an air circuit. The one or more processors may set one or more supplementary oxygen parameters associated with introducing supplementary oxygen into the flow of air at the air circuit. The method may involve computing an oxygen performance metric associated with characteristic(s) of a patient and the air flow with the supplementary oxygen. The computing may include applying function(s) comprising the therapy parameter(s) and supplementary oxygen parameter(s). Output, such as a display indicator or automated therapy control change(s), may be generated using the computed oxygen performance metric. Changes to therapy parameter(s) may be made to optimise the metric.

摘要： A positive airway pressure (PAP) device for supplying a flow of breathable gas to a patient includes a flow generator configured to pressurize a flow of breathable gas and a humidifier configured to receive and humidify the pressurized flow of breathable gas from the flow generator. The PAP device also includes a power source. The flow generator, humidifier and power source are positioned so that heat generated by at least one of the flow generator and the power source is conveyed to water in the humidifier.

摘要： Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators. In some cases, instantaneous impedance or conductance may be used to assess re-connection of a patient circuit, detection of flow starvation, determine breath shape for triggering and cycling and to detect patient or circuit obstructions.

摘要： An oxygen concentrator 100 apparatus and a method thereof implement operations control to efficiently release oxygen enriched gas to reduce potential waste. The control methodology may include generating a profile such as a minimum inhalation flow profile of the user. The profile may be based on a size parameter of the user. The method may determine one or more control parameters characterizing a bolus of oxygen enriched gas based on the generated flow profile. The control methodology may then generate a bolus release control signal, such as for a supply valve, according to the determined one or more control parameters. The oxygen concentrator may then, with the control signal, release and deliver a bolus of oxygen enriched gas for a user such as for reducing waste.

摘要： Apparatus, such as a respiratory therapy device 4000, may generate a signal representing an estimate of a patient breathing pattern when using a flow therapy device with an un-sealed patient interface. The device may include a blower and may generate a flow of air at a controlled flow rate. The apparatus may include a controller. The generation may involve computing an estimate of the breathing pattern as a function of a device flow rate signal; a device pressure signal; a device conductance; a patient conductance; and a coupling parameter that characterizes a degree of coupling between the interface and the patients nares. An estimate of an exit pressure representative of a pressure of a flow of air generated by the therapy device just outside an orifice of the unsealed interface may also be computed. An estimate of a flushing flow rate from the estimated exit pressure may also be computed.

摘要： Methods and apparatus provide automated controls for a respiratory pressure therapy device, such as a servo-ventilator. For example, a controller of a respiratory pressure therapy device may control application of pressure support ventilation therapy to an airway of a patient. The controller may control the respiratory pressure therapy device to auto-titrate an expiratory positive airway pressure (EPAP) of a pressure support ventilation therapy so as to maintain airway patency of the patient. The EPAP may be bounded below by a floor pressure limit. The controller may control the respiratory pressure therapy device to repeatedly adjust the floor pressure limit depending on events of interest during the auto-titration of the EPAP. Such methodologies may improve treatment for patients such as those suffering from sleep disordered breathing-comorbid hyperarousal disorders.

摘要： Apparatus and methods provide control for generation of a flow of air to a patient's airways for different respiratory therapies. The pressure and a flow rate may be simultaneously controlled so as to provide a pressure therapy and a flow therapy. The system may include one or more flow generators, in which the control of the pressure and flow rate may include altering the output of one or more of the flow generators and/or an optional adjustable vent. The pressure and flow rate may each be held at a constant. One or both of the pressure and flow rate may also vary in accordance with a desired therapy. The air may be provided via a patient interface that includes a vent to atmosphere, which may be the adjustable vent. The vent may be actuated by a controller to implement the simultaneous control of pressure and flow rate of the air.

摘要： Methods and apparatus involve generation of an anti-infection therapy. The method/apparatus may include a controller controlling setting of a respiratory flow therapy device for the therapy. The controller may compute a target flow rate profile for a patient using a margin function, such that the target flow rate profile, according to the margin function, exceeds a minimum inspiratory flow rate profile of the patient's inspiration. The controller may control setting the respiratory flow therapy device to generate a flow of air to a patient interface according to the target flow rate profile, where the generation may be in synchrony with a sensed parameter that is indicative of a breathing cycle of the patient.

摘要： A mask assembly for delivering pressurized gas to a patient comprising a mask having an inspiratory port and an expiratory port located on generally opposite sides, wherein said ports are sized, oriented, positioned, and/or spaced apart a sufficient distance to allow a cross-flow of pressurized gas to flow through the mask assembly; an outlet limb connected to the expiratory port and having an aperture in pneumatic communication with the breathing chamber; the aperture size being variable between a first, open configuration and at least one second configuration that is different from the first. A ventilation system for delivering pressurized gas to a patient comprising a seal formed with the patient's airways and in pneumatic communication with a plenum chamber; an exchanger positioned at least partially within the plenum chamber, and in pneumatic communication with inspiratory and expiratory flow paths, to recover heat and/or moisture from gas exhaled by the patient.
