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: A mechanical insufflation-exsufflation device including an air source to provide positive airway pressure (PAP); a patient interface; at least one sensor to sense air pressure and flow at the patient interface; and a controller to control the air source to deliver at least one mechanically assisted cough to the patient in response to at least one of a target breathing flow and a target inhalation time period being sensed by the at least one sensor, and when the at least one of a target breathing flow and a target inhalation time period is not sensed, the controller is configured to control the air source to deliver each in a series of high-level PAP provided over a duration being followed by a low-level PAP provided over a duration, the series of high-level PAP increasing in pressure level and duration from a prior one in the series of high-level PAP.

IPC: A61M16/00
Abstract: A ventilation apparatus has a breathing gas delivery system for delivering breathing gas to a user of the apparatus as ventilation therapy, with a controllable pressure and flow. The breathing pressure and flow are monitored to derive a respiration variability. A state of relaxation of the user is derived during provision of breathing assistance based on at least the respiration variability. Settings of the ventilation apparatus are then adapted dependence on the estimated state of relaxation for assisting the user in habituating to the breathing assistance, and hence habituating to breathing therapy.

Abstract: An embodiment provides techniques for distinguishing between breathing events based on sensor data obtained from one or more wearable sensors. In one example, sensor data is obtained that includes one or more of a sensor signal and descriptive metadata of the sensor signal. Processing is applied to distinguish between a cough and another breathing event based on the sensor data, and an indication of a cough is provided.

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.
