Publication number: 20240024602Abstract: A breathing assistance apparatus for providing respiratory therapy such as bubble CPAP therapy comprises a flow generator, a gases flow pathway, a pressure regulator, a gases property sensor and a controller. The controller of the apparatus can be configured to detect the presence of bubbling in the pressure regulator based on the at least one waveform characteristic from a measured flow and/or pressure waveform.Type: ApplicationFiled: September 21, 2021Publication date: January 25, 2024Inventors: Malik Tivanka Rajiv Peiris, Simei Gomes Wysoski

Publication number: 20230130469Abstract: An automatic positive airway pressure (AutoPAP) therapy device can be configured such that the minimum and/or maximum pressures deliverable by the device can automatically change. The minimum and/or maximum pressures can change as a function of pressures delivered over the course of the current therapy session and/or over the course of prior therapy sessions. The minimum and/or maximum pressures can also change as a function of the presence, absence, type, severity, or length of sleep disordered breathing events (SDBE) detected by the device over the course of the current therapy session and/or over the course of prior therapy sessions.Type: ApplicationFiled: December 21, 2022Publication date: April 27, 2023Inventors: David Robin Whiting, Simei Gomes Wysoski

Patent number: 11617846Abstract: A multi-night titration (MNT) process to find an optimal single therapeutic pressure of a CPAP device. This single therapeutic pressure can then be used on an on-going basis by the patient after the titration period. The MNT process differs from current auto adjusting processes used for titration (or ongoing use) in that the MNT process does not respond locally by adjusting pressures to individual events. With existing devices, the continuous adjustment of supplied air pressure always responds to one or a small number of events and thus fails to compensate for a patient's adaptation thereto, resulting in the supply of a less than optimal therapeutic pressure to the patient. While auto adjusting processes often capture and respond well to short-term and transient conditions, the MNT process of the current disclosure seeks to capture long term trends and find the most suitable average single pressure for a patient.Type: GrantFiled: April 16, 2020Date of Patent: April 4, 2023Assignees: FISHER & PAYKEL HEALTHCARE LIMITED, NEW YORK UNIVERSITYInventors: David M. Rapoport, Indu Ayappa, Simei Gomes Wysoski, Sujeewa Wannigama, David Robin Whiting

Publication number: 20220347423Abstract: Described is a respiratory therapy system that comprises a respiratory therapy apparatus that is configured to provide a flow of breathable gas at, at least a first pressure and a second pressure to a patient. The respiratory therapy apparatus comprises a flow generator configured to provide the flow of breathable gas, a controller, coupled to a trigger sensor, to control respiratory therapy apparatus operations, a breathing conduit assembly that conveys the breathable gas to a patient via a patient interface, a trigger that produces a signal detectable by the trigger sensor. The controller is configured to control the flow generator to provide the flow of breathable gas at, at least the first pressure or the second pressure based on detection of the signal from the trigger.Type: ApplicationFiled: September 9, 2020Publication date: November 3, 2022Inventors: Sean Joel BABBAGE, Simei Gomes WYSOSKI, Sarah Emily LOWE, Andrew Paul Maxwell SALMON, Christopher Harding CAMPBELL, Hamish CHAN, Kevin Peter O'DONNELL

Publication number: 20220313155Abstract: A method and system of determining a sleep stage of a user involves receiving a respiratory flow signal of a user, obtaining at least one respiratory feature from at least part of the respiratory flow signal, and determining a sleep stage from the at least one respiratory feature.Type: ApplicationFiled: March 2, 2022Publication date: October 6, 2022Inventors: Simei Gomes Wysoski, David Robin Whiting
-
Publication number: 20220168536Abstract: Respiratory systems with a flow generator can provide bubble CPAP therapy by controlling the pressure of a flow of gas delivered to a patient. The controller of the respiratory system can control a motor speed of its flow generator so as to control the pressure of the flow of gas. The controller can also detect presence of bubbling and/or possible leaks in the gas pathway of the system. The respiratory system can include a high flow respiratory system.Type: ApplicationFiled: March 20, 2020Publication date: June 2, 2022Inventors: Peter Chi-Yang HSU, Simei Gomes WYSOSKI

Publication number: 20220031987Abstract: We provide a respiratory therapy system comprising: a flow generator; a humidifier; a respiratory conduit a patient interface coupled to the respiratory conduit to deliver a gases flow to a patient; a sensor configured to determine pressure or flow of the gases flow; a controller configured to control the flow generator to generate the gases flow; and the controller configured to: a) retrieve at least one first signal associated with or indicative of a gases flow and/or pressure in the respiratory conduit; b) determine a measure of at least one first parameter associated with gases flow perturbations and/or pressure perturbations for at least one portion of the retrieved at least one first signal; and c) determine the presence of liquid in the respiratory conduit based at least in part on the measure(s) of the at least one first parameter meeting a first threshold. The system can be used to reduce or alleviate condensation in a respiratory gas deliver conduit.Type: ApplicationFiled: December 13, 2019Publication date: February 3, 2022Inventor: Simei Gomes WYSOSKI

Publication number: 20210338951Abstract: Apparatuses and methods for detecting sleep apnea and classifying the events as obstructive sleep apnea (OSA) and/or central sleep apnea (CSA) are disclosed herein. The apparatuses can include respiratory treatment devices that have an auto adjusting algorithm that is able to classify a sleep apnea as CSA or OSA so that an appropriate pressure can be applied to the patient depending on the type of sleep apnea detected. The apparatuses and methods can use characteristics of at least one breath preceding the apnea event in classifying the event.Type: ApplicationFiled: May 21, 2021Publication date: November 4, 2021Inventors: David Robin WHITING, Amol Man MALLA, Simei Gomes WYSOSKI
