Abstract: The apparatus (102) forms part of a respiratory system, such as an endotracheal tube, and includes a sound conduit (108) adapted to direct an acoustic signal (A1) to an anatomical cavity of a user of the apparatus (102). A sound generator generates the acoustic signal and a microphone, which is coupling with the sound conduit (108), generates a measure of the acoustic signal (A1). A processor analyses data samples of the measure of the acoustic signal (A1) from the microphone by calculation of a cepstrum with the data samples of the measure of the acoustic signal (A1). The processor then determines the connection of a patient interface to the airpath based on the analysis.

Abstract: An apparatus for automated control of gas washout of a patient interface of a respiratory treatment apparatus comprising: a vent assembly having a variable size exhaust area defined by one or more overlapping apertures (90, 95), wherein in use the vent assembly vents expiratory gas from the patient interface; and an actuator to manipulate said one or more overlapping apertures of the vent assembly. The variable size exhaust area is configured to be set to a plurality of open positions, the plurality of open positions providing different opening area sizes for venting expiratory gas from the patient interface.

Abstract: 613721 613721 Systems, devices and methods of use adapted for treatment of respiratory disease or sleep disordered breathing include a patient interface (10) adapted to be secured to and sealed against a portion of a patient’s face, in use. A flow generator is adapted to be connected to the patient interface and to be secured by a portion of the patient’s body. The flow generator includes a blower (not shown) adapted to provide pressurised breathable gas to a patient through the patient interface. The blower is adapted to be at least partially vibrationally isolated from the patient’s body by at least one dampening system (not shown) or device. The dampening device or system is adapted to reduce the amount of transmitted vibration received by the patient. A PAP system includes a patient interface including sealing arrangement (30) adapted to form a seal with the patient’s nose and/or mouth and headgear (40) to support the sealing arrangement in position on the patient’s head. A blower is structured to generate a supply of pressurized air. The blower is supported by the patient interface on the patient’s head and in communication with the patient interface. The headgear forms one or more ducts (42) to communicate pressurized air from the blower to a breathing cavity defined by the sealing arrangement.

Abstract: Respiratory pressure treatment apparatus include automated methodologies for controlling changes to pressure in the presence of sleep disordered breathing events. In an example apparatus, various levels of expiratory pressure relief can provide different pressure reductions for patient comfort during expiration (333-A, 333-B, 333-C). The control parameters for these levels may be automatically modified based on the detection of an open airway. Similarly, in some embodiments, the levels may be automatically adjusted based on a detection of persistent obstruction. In still further embodiments, control parameters associated with a rise time of an early portion of an inspiratory pressure treatment may be automatically adjusted upon detection of flow limitation to permit a change to more aggressive waveforms from more comfortable waveforms for the treatment of sleep disordered breathing events. cli w x c x w 0 (Y)

Abstract: 594185 Disclosed is a method for detecting a respiratory treatment conduit obstruction. A sound sensor determines a measure of sound of a flow generator (110) within a respiratory treatment conduit and a processor analyses the measure of sound from the sound sensor. The processor then indicates a presence or absence of obstruction in the respiratory treatment conduit based on the analysing.

Abstract: A motor with shaft and an impeller mounted on the shaft is for a blower so that the impeller will rotate in close proximity to the volute casing. The motor is provided with a means, in the circuit board, typically a protruding sensor, that is used to sense movement of the shaft/impeller towards the volute casing and disable the motor.

Abstract: A mask assembly (30) is provided with a filter assembly (48) to filter gas exhaled by a patient during the administration of ventilatory therapy, e.g., CPAP or bi-level treatment, to reduce or eliminate the possibility of cross-infection to other patients or the physician in a clinical setting.

Abstract: A multiple-stage variable speed blower (100) for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers (114, 115) in the gas flow path that cooperatively pressurise gas to desired pressure and flow characteristics. The blower includes an external inlet (118), a first volute (112), a duct (116) for take air to the second impellor, and a second volute (113), the air exiting the blower via an external outlet (120). Thus, the multiple-stage blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.
