摘要： A system for identifying a body position of a user of a respiratory therapy system includes a sensor, a memory, and a control system. The sensor is configured to generate airflow data associated with the user. The memory stores machine-readable instructions. The control system includes one or more processors configured to execute the machine-readable instructions to receive the airflow data associated with the user during a sleep session. The control system is further configured to determine one or more features associated with the airflow data, and identify the body position of the user during a first portion of the sleep session based at least in part on the determined one or more features. The control system is further configured to cause an action to be performed based at least in part on the identified body position of the user.

摘要： A system includes a respiratory therapy system, a memory device, and a control system. The respiratory therapy system includes a respiratory therapy device supplying pressurized air, and a user interface coupled to the respiratory therapy device via a conduit to direct the pressurized air to an airway of a user. The memory device stores machine-readable instructions. The control system includes a processor(s) to execute the machine-readable instructions to: generate data, during a current sleep session, associated with a user of a respiratory therapy system; analyze the generated data to determine a value of a first metric that is associated with a sleep disordered breathing (SDB) condition; analyze the generated data to determine a value of a second metric that is associated with a health condition other than the SDB condition; and based at least in part on the determined value of the second metric, cause an action to be performed.

摘要： A method of an apparatus control pressure in the patient interface. A vent valve may be used with a respiratory device, where the vent valve may selectively block fluid communication between components, such as the flow generator, the patient interface, and/or the vent. An expiratory flow model may be used to determine an expiratory characteristic such as an expiratory flow rate or pressure in the patient interface where an indicative measure may not be available. The expiratory flow model may receive inputs based on a measure of the patient's respiration, such as the tidal volume, peak inspiratory flow rate or length of inspiration. The expiratory characteristic may be used by a controller to control a pressure in the patient interface to provide respiratory therapy to a patient at or close to a target pressure.

摘要： A respiratory valve, such as a positive end expiratory pressure valve, permits pressure control for respiratory apparatus such as a ventilator or positive airway pressure device. The valve may include a flexible gas passage cover. The cover may be configured with a first side surface to operatively block and open an aperture of the gas passage at a valve seat to respectively prevent and permit gas flow through the aperture defined by the valve seat. The cover may include a second side surface opposite the first surface. The second surface may include at least one drop section forming a reduction in thickness of the cover between the first surface and the second surface. The first surface may include a coating to reduce friction of a membrane material of the first surface. The rim of the valve seat may comprise a variation in height relative the flexible cover.

摘要： Methods and apparatus provide acoustic detection for automated devices such as respiratory treatment apparatus. In some embodiments of the technology, acoustic analysis of noise or sound pulses, such as a cepstrum analysis, based on signals of a sound sensor (104) permits detection of obstruction (O) such as within a patient interface, mask or respiratory conduit (108) or within patient respiratory system. Some embodiments further permit detection of accessories such as an identification thereof or a condition of use thereof, such as a leak. Still further embodiments of the technology permit the detection of a patient or user who is intended to use the automated device.

摘要： A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modeled based on the transformed data set.

摘要： A method, such as in a controller associated with a respiratory therapy device, determines whether high flow therapy is being used by a patient. The method may include determining whether a property of a flow of air being delivered by a respiratory therapy device along an air circuit to an unsealed patient interface contains a significant oscillation within a breathing rate frequency band. The method may also include generating, dependent on the determination, an indication of whether high flow therapy is being used by the patient.

摘要： An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration.

摘要： A respiratory therapy (RT) system including one or more acoustic generators (8500) to produce an inaudible acoustic signal. The acoustic generator(s), such as when coupled to a patient interface or air circuit of a respiratory therapy device, may provide inaudible acoustic signals indicative of one or more parameters, such as a flow rate or a pressure of the flow of air, or a type of or useable life of a component (e.g. patient interface). The system may have an acoustic receiver that may detect one or more acoustic signals from the acoustic generator, the RT system, the patient or the environment.

摘要： Apparatus to permit a delivery of a flow of breathable gas to a patient's airways. In one version, a coupler extension may include a seat portion to permit use of a mask with a nasal cannula. In some versions, the coupler extension is configured to conduct the flow of gas to prongs of a nasal cannula. The seat portion can receive and seal with a cushion of a respiratory mask and may have a sealing bevel to promote sealing between the cushion of the respiratory mask and a facial contact surface of a user. In some versions, a conduit adapted to communicate a flow of gas may comprise a slit valve formed by a portion of the wall material of the conduit. In some versions, a nasal interface may include naris pillows to seal with and conduct a flow of breathable gas into a nares of a user. Each naris pillow may include a nasal projection to conduct a further flow of gas. The nasal projection may extend within the naris beyond the seal of the naris pillow.
