  • Patent number: 10342939
    Abstract: Automated methods provide a ventilation sufficiency assessment to evaluate patient respiration. In some embodiments, a ventilation histogram maybe determined from a measure of patient respiratory flow. Based on the histogram or associated ventilation data, hypoventilation or hyperventilation occurrences may be detected. For example, a kurtosis index and/or skewness index may be calculated with the data associated with the ventilation histogram and may be evaluated as an indication of hypoventilation or hyperventilation. An assessment of the number of peaks and other features of the ventilation histogram, such as in the case of a bimodal ventilation histogram, may be implemented to detect an occurrence of ventilation insufficiency or sufficiency. The detection methodologies may be implemented by a specific purpose computer, a detection device that measures a respiratory airflow or a respiratory treatment apparatus that provides a respiratory treatment regime based on the detected ventilation sufficiency.

  • Patent number: 10315002
    Abstract: A method of providing a breath to a human patient. The patient has a patient connection connected, by a patient circuit, to a ventilator having a first ventilator connection and a different second ventilator connection. Each of the first and second ventilator connections are in fluid communication with the patient circuit. The method includes identifying, with the ventilator, initiation of an inspiratory phase of the breath, delivering a bolus of oxygen to the first ventilator connection before or during the inspiratory phase, and delivering breathing gases comprising air to the second ventilator connection during the inspiratory phase. The ventilator isolates the bolus of oxygen delivered to the first ventilator connection from the breathing gases delivered to the second ventilator connection.

  • Patent number: 10314989
    Abstract: Described here are positive airway pressure (PAP) systems and methods with various mechanisms for altering the air pressure based in part on the head position of the user. This can be achieved actively or passively. Passively, pressure is altered when head position is altered, as gravity acts to open or close venting elements. Actively, head position information can then be communicated to a controller of the system which may be disposed within the housing having the position sensor or within a separate housing. The controller varies the output pressure of the pressure source, e.g. a rotary compressor, based, at least in part, on the head position information provided.

  • Patent number: 10293126
    Abstract: The present disclosure pertains to a mechanical ventilator system configured to deliver a pressurized flow of breathable gas to the airway of a subject. The system is configured to generate the pressurized flow of breathable gas according to a volume control mode therapy regime that delivers a target tidal volume to the subject during inhalation. During an individual inhalation, the system is configured to determine and/or adjust an inspiratory pressure level of the pressurized flow of breathable gas of the volume control mode therapy regime. The inspiratory pressure level is adjusted such that during the inhalation the inspiratory pressure level is not reduced to impede respiratory effort by the subject responsive to the target tidal volume being exceeded during the inhalation. The system comprises one or more of a pressure generator, a subject interface, one or more sensors, one or more processors, a user interface, electronic storage, and/or other components.
