Publication number: 20240075227Abstract: A positive airway pressure apparatus is automatically adjusting. Pressure increases in response to apnea events when the apparatus is in one or more responsive states. Pressure does not increase in response to apnea events when the apparatus is in a non-responsive state. The apparatus switches between responsive and nonresponsive states depending upon any of a number of different criteria that help differentiate between open airway apnea events and closed airway apnea events.Type: ApplicationFiled: July 13, 2023Publication date: March 7, 2024Inventors: David Robin Whiting, Andrew Gordon Gerred, Fiona Elizabeth Cresswell

Publication number: 20220031984Abstract: An apparatus and method of controlling the delivery of therapeutic gas delivered to a patient undergoing positive airway pressure therapy is described. The method includes providing a flow of gas to a patient's airway at a pressure, obtaining information from the range of 0 to 25 Hz of the frequency domain of the flow, and adjusting the pressure based on the information. The apparatus includes a blower for providing a flow of gas to a patient's airway at a pressure, a sensor to measure a characteristic of the flow, a controller to obtain information from the range of 0 to 25 Hz of the frequency domain of the characteristic, and a pressure regulator for adjusting the pressure based on the information.Type: ApplicationFiled: September 23, 2021Publication date: February 3, 2022Inventors: Lewis George Gradon, David Robin Whiting, Andrew Gordon Gerred, Gregory Martyn Smith, Fiona Elizabeth Cresswell

DELIVERING VARIABLE POSITIVE AIRWAY PRESSURE DEPENDING ON AWAKE STATE AND SLEEP DISORDERED BREATHING
Publication number: 20210187218Abstract: Positive airway pressure (“PAP”) systems and methods are provided which supply a patient with a range of pressures for treatment when the patient is determined to be asleep, and an awake pressure for use when the patient is determined to be awake, the awake pressure configured for the comfort of the patient. The awake pressure is configured to be lower than the lower bound of the pressure range and can be a therapeutic or sub-therapeutic pressure. The PAP systems and methods disclosed herein advantageously allow for the pressure range to be tailored for effective treatment of sleep disordered breathing while allowing the awake pressure to be set for the comfort of the patient. This can advantageously increase both the efficacy of the treatment of SDB and patient compliance with the treatment.Type: ApplicationFiled: February 23, 2021Publication date: June 24, 2021Inventors: Andrew Gordon Gerred, David Robin Whiting -

Publication number: 20190175857Abstract: The present disclosure provides for non-invasive bi-level (BPAP) pressure control where the pressure of breathable gas supplied to the patient switches between an inspiration pressure during inspiration (IPAP) and another, usually lower, expiration pressure during expiration (EPAP). The present disclosure provides a system configured to prevent premature triggering to IPAP after a timed breath in spontaneous/timed mode (S/T mode) by preventing spontaneous triggering to IPAP after a timed breath until an expiration has been confirmed.Type: ApplicationFiled: December 7, 2018Publication date: June 13, 2019Inventors: David Robin WHITING, Andrew Gordon GERRED
