Publication number: 20210330910Abstract: Systems or apparatus may be configured with method(s) for hyperarousal disorder such as for determining settings that control respiratory therapy for slowing a patients breathing. They may be configured to determine an interim target breathing rate less than a current spontaneous rate. They may be configured to derive target inspiratory time and expiratory times based on the interim target breathing rate. They may be configured to compute, with first function(s), a parameter set for generating a variable treatment pressure waveform based on target inspiratory/expiratory times. They may be configured to determine pressure settings by generating the waveform with the computed parameter set and second function(s). They may be configured to reduce the interim target breathing rate in response to a subsequent spontaneous breathing rate slowing down toward the interim target rate. They may be configured to generate feedback such as graphics/sound to provide information to promote slowing of breathing.Type: ApplicationFiled: February 15, 2019Publication date: October 28, 2021Applicant: ResMed Pty LtdInventors: Bodiyabaduge Dimithri Joseph PERERA, Dinesh RAMANAN, Gordon Joseph MALOUF, Liam HOLLEY, Neha BANODKAR

Publication number: 20200338299Abstract: Methods of an apparatus determine a quantity of a body of water in a humidifier such as by indirect measurement. The quantity of water may be determined by measuring one or more properties or characteristics, from which the quantity of water may be inferred. Characteristics of a flow of air, the humidifier, and/or the body of water may be measured. The characteristics may be, for example, pressure, flow rate, noise, vibration, temperature, electrical or mechanical. These may be measured by one or more sensors, which may be located in the humidifier, RPT device, air circuit or the patient interface. The methods described may have advantages, for example in being able to detect the quantity of water without requiring sensors to be present in a disposable component, and in some cases, without introduction of additional sensors.Type: ApplicationFiled: July 9, 2020Publication date: October 29, 2020Applicant: ResMed Pty LtdInventors: Andrew Roderick BATH, Matthew Rolf HARRINGTON, Liam HOLLEY, Ronald James HUBY, Richard Llewelyn JONES, Ian Malcolm SMITH

Publication number: 20200246564Abstract: 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.Type: ApplicationFiled: February 7, 2020Publication date: August 6, 2020Applicant: ResMed Pty LtdInventors: Liam HOLLEY, Paul Jan KLASEK, Robert Henry FRATER, Quangang YANG, Pallavi GOSAIN
