    Abstract: A cuff pressure management device (10) for a tracheal breathing tube (54) with an inflatable cuff (90), comprises a volume displacement subsystem (36), a pressure transducer (44), a compliance determination circuit (34), and a cuff pressure controller (24). The volume displacement subsystem provides (i) a measured volume of pressurized gas to and from the cuff and (ii) a cuff gas volume signal. The pressure transducer provides a cuff gas pressure signal. The compliance determination circuit is configured to calculate cuff compliance and an estimated tracheal airway compliance based on the gas volume signal and the gas pressure signal. The cuff pressure controller is in controlling communication with the volume displacement subsystem and the compliance determination circuit to maintain cuff pressure based on the calculated cuff compliance.

    Abstract: A mechanical ventilation system comprises a mechanical ventilator configured to deliver ventilation to a patient. An electronic controller is programmed to control the mechanical ventilator to perform a mechanical insufflation-exsufflation (MI-E) therapy method including performing a MI-E cycle including: (i) during an insufflation cycle, delivering pressure to the patient at a positive insufflation gauge pressure; (ii) during an exsufflation cycle following step (i), delivering pressure to the patient at a negative exsufflation gauge pressure and detecting whether an upper airway collapse occurs; and (iii) reducing a magnitude of the negative exsufflation gauge pressure if an upper airway collapse is detected in step (ii).

    Abstract: The present disclosure pertains to a method and system configured for cough synchronization in a mechanical insufflation-exsufflation system. The system is configured to synchronize (712) the transition from an insufflation mode to an exsufflation mode to a patient initiated cough by detecting cough effort of the patient e.g. at the end of the insufflation phase. The detection of cough effort of the patient is based on one or more parameters associated with gas in the system. Upon detecting that the patient is initiating a cough, the system automatically switches the insufflation mode to the exsufflation mode to assist the patient to generate an effective cough.

    Abstract: A system and method to in-exsufflate a subject is described. The system provides an effective non-invasive alternative to invasive treatments such as a tracheostomy for ALS patients. The system detects airway collapse during exsufflation and adjusts in-exsufflation therapy settings to minimize airway collapse, thus maximizing the efficacy of the in-exsufflation therapy. In some embodiments, tidal volume, tidal flow rate, and/or other parameters are monitored during in-exsufflation. Exsufflation pressure is adjusted based on the monitored parameters to maintain an open airway during exhalation of the subject. Exsufflation pressure is adjusted based on a comparison of an actual exhalation tidal volume to a target exhalation tidal volume, an actual exhalation flow rate to a target exhalation flow rate, an actual inhalation tidal volume to a target inhalation volume, and/or other comparisons.

    Abstract: A mechanical ventilation system includes a mechanical ventilator configured to deliver ventilation to a patient. An electronic controller is programmed to control the mechanical ventilator to perform a lung volume recruitment (LVR) therapy method. The LVR therapy method includes at least one LVR cycle including: an inspiration phase in which air is delivered to an upper airway of the patient by the mechanical ventilator to ramp an airway pressure up to an LVR pressure of the LVR cycle, a hold phase in which the airway pressure is maintained by the mechanical ventilator at the LVR pressure or at a pressure above the LVR pressure for a hold time interval, and an expiration phase in which the airway pressure decreases to a positive end-expiratory pressure (PEEP) of the LVR cycle.

    Abstract: The present disclosure pertains to a system and method for controlling insufflation pressure during inexsufflation of a subject. The system inexsufflates the subject such that tidal flow and/or tidal volume are monitored during insufflation, and insufflation pressure is adjusted to maintain the flow rate of the pressurized flow of breathable gas until a target tidal volume is reached for the insufflation. When the target tidal volume has substantially been reached, the system is causes gas to be evacuated from the airway of the subject. This may provide for more precise, customized therapy for the subject than is provided by conventional inexsufflation systems in which inspiratory flow may not be monitored and/or controlled. In one embodiment, the system comprises one or more of a pressure generator, a subject interface, one or more sensors, a processor, a user interface, electronic storage, and/or other components.
