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

Patent number: 11918739Abstract: A breathing gases supply apparatus 1 can comprise a blower 103/105 and breathing circuit for delivering breathing gases to a patient. The apparatus also can comprise a first controller 109, the controller 109 configured to receive input from at least one sensor 110-112 indicative of patient breathing, and a transmitter 201 configured to communicate with the controller 109 and transmit control signals to an electronic apparatus 203. The controller 109 can be configured to determine sleep in a patient based on the occurrence of a breathing pattern indicative of sleep, detected from the input received from the sensor 110-112 and upon determining sleep, operate the transmitter 201 to send a control signal to control an electronic apparatus 203.Type: GrantFiled: October 1, 2020Date of Patent: March 5, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: James Malcolm Thompson, Fiona Elizabeth Cresswell, Donald Roy Kuriger

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
