  • 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.

  • Patent number: 10286170
    Abstract: A cuff pressure stabilizer includes a substantially rigid protective housing and a balloon disposed therein. The balloon has a base low pressure of 10 cm H2O when it contains a base low-pressure volume of air. When the balloon contains a first medium-pressure volume of air, the balloon has a first medium pressure of 25 cm H2O, and less than 10% of an outer surface of the balloon touches an inner surface of the housing. When the balloon contains a second medium-pressure volume of air, the balloon has a second medium pressure of 40 cm H2O, and at least 20% of the outer surface of the balloon touches a portion of the inner surface of the housing. The second medium-pressure volume of air equals the base low-pressure volume of air plus a second incremental quantity of air that is between 10 cc and 60 cc. Other embodiments are also described.

  • Patent number: 10279133
    Abstract: The function of a respiration system, with a patient port (1) with connected inspiration branch (3) and expiration branch, is checked. A rebreathing line (9) connects the inspiration branch to the expiration branch. A reservoir (25) is connected to a reservoir port (27) in the rebreathing line. An actuatable control valve (29) is provided in the rebreathing line between the expiration branch and the reservoir port. A pressure sensor (33) is connected to the rebreathing line. A control unit (39) is connected to the control valve and to pressure sensor. The process includes closing the control valve for a preset inspiration time and opening it for a preset expiration time. The value sent by the pressure sensor is detected with the control valve opened during the expiration time and compared with a preset first threshold valve. An error message is generated when the value sent exceeds the first threshold value.
