Publication number: 20170216542Abstract: A controller or processor for a respiratory pressure treatment device determines an estimate of patient respiratory flow based on a measure of pressure associated with flow generated by a flow generator and a measure of frequency of the flow generator, such as a rotational velocity of a servo-controlled blower motor. The estimate can be made without data from a flow sensor. The measure of frequency may be converted to an expected pressure based on characteristics of the flow generator and subtracted from the measured pressure to determine the flow estimate. The flow estimate can be implemented in the provision of respiratory pressure treatment with the flow generator. For example, the flow estimate may be utilized to trigger expiratory pressure relief during a patient's expiration as detected with the estimated flow signal.Type: ApplicationFiled: April 11, 2017Publication date: August 3, 2017Applicant: ResMed LimitedInventors: Chinmayee Somaiya, Nicholas Ming Yun Yip, John David Oates, Adrian Barnes, Christopher Kingsley Blunsden

Patent number: 9707361Abstract: CPAP treatment apparatus (10), as one form of positive pressure ventilatory assistance, is disclosed. A turbine/blower (14), operated by a mechanically coupled electrical motor (16), receives air or breathable gas at an inlet (18) thereof, and supplies the breathable gas at a delivery pressure to a delivery tube/hose (20) having connection at the other end thereof with a nose mask (12). A microcontroller (38) has an operational “Mask-Fit” mode. An initial constant pressure level is applied by the blower (14) to the mask (12). If the functional mode is a Manual mode, then the mask-fit test pressure is the current ‘set’ pressure. If the functional mode is the Automatic Titration mode, the mask-fit test pressure is the 95th percentile pressure of the previous session, otherwise it is the base treatment pressure, e.g. 10-12 cm H2O. This constant pressure is applied for a period of time, typically 1-3 minutes.Type: GrantFiled: July 18, 2006Date of Patent: July 18, 2017Assignee: ResMed LimitedInventors: Gregory Newton Brewer, Gregory Alan Colla, Steven Paul Farrugia, Chinmayee Somaiya

Publication number: 20160158478Abstract: A modularized respiratory treatment apparatus provides various respiratory pressure treatments. The apparatus may be formed by discrete connectable modules such as a flow generator module, alarm module and/or humidifier module. Each module may include its own external casing or housing to independently retain or enclose the respective components that serve the function of the module. Different modules may be adapted with different components and functionalities and may be readily coupled using standardized gas and electrical connection configurations that have flow and communication paths that extend through the modules. When coupled, operation of the respiratory treatment apparatus may be controlled by detection of different modules, such as the alarm module that generates visual and/or audible alarms based on detected conditions, so as to selectively enable or disable different respiratory treatments.Type: ApplicationFiled: February 12, 2016Publication date: June 9, 2016Inventors: Mark Bertinetti, Zhuo Ran Tang, Craig Laing, Jing Wen Xie, Jianhua Zhu, Chinmayee Somaiya, Graham Stephen Cutcliffe, Sandra Robyn Curtis, Peter Milliken, Dimitri Marco Maurer

Publication number: 20150165145Abstract: CPAP treatment apparatus is disclosed having a controllable positive airway pressure device. A sensor generates a signal representative of patient respiratory flow that is provided to a controller. The controller is operable to determine the occurrence of an apnea from a reduction in respiratory airflow below a threshold determined from long term ventilation. When an apnea or hypopnea has occurred the calculation of the threshold is suspended until the end of that event.Type: ApplicationFiled: December 3, 2014Publication date: June 18, 2015Inventors: Matthew Alder, Steven Paul Farrugia, Chinmayee Somaiya

Publication number: 20140142457Abstract: In a respiratory apparatus for treatment of sleep apnea and other disorders associated with an obstruction of a patient's airway and which uses an airflow signal, an obstruction index is generated which detects the flattening of the inspiratory portion of the airflow. The flattening index serves as an obstruction index used to differentiate normal and obstructed breathing. The obstruction index is based upon comparison of values of airflow in different sectors of the inspiratory peak of the wave function and is particularly suitable for distinguishing M shaped or square shaped respiratory patters indicative of partially obstructed airways.Type: ApplicationFiled: November 18, 2013Publication date: May 22, 2014Applicant: RESMED LIMITEDInventors: Jeffrey Peter Armitstead, Chinmayee Somaiya

Patent number: 8365729Abstract: A CPAP apparatus is provided that determines the presence of a snore by the simplified method of using filtered expiratory noise as the measure of intrinsic device noise and comparing that to filtered inspiratory noise. The filtering time constants for inspiratory and expiratory noise are adjusted such that treatment pressure does not cause false snore detection.Type: GrantFiled: January 4, 2007Date of Patent: February 5, 2013Assignee: ResMed LimitedInventors: Matthew Alder, Steven Paul Farrugia, Chinmayee Somaiya, Kristian Thomsen

Publication number: 20100258123Abstract: Systems and/or methods for treating sleep-disordered breathing (SDB) are provided. In particular, systems and/or methods are provided that include software systems for use with auto-titrating devices (e.g. APAP devices) that reduce and/or eliminate the need to calibrate the auto-titrating devices. The software system also may reduce and/or eliminate the need for certain sensors used in such calibrations. Certain example embodiments compute snore based on noises measured during expiration and inspiration, and certain example embodiments set patient leak utilizing the vent flow level. Certain example embodiments change treatment pressure thresholds after measuring patient improvement by monitoring a variable correlated with actual delivery pressure in accordance with an example embodiment, and certain example embodiments provide pressure according to motor speed in accordance with an example embodiment.Type: ApplicationFiled: June 5, 2007Publication date: October 14, 2010Applicant: ResMed LimitedInventors: Chinmayee Somaiya, Steven Paul Farrugia, Matthew Alder, Kristian Thomsen
