A combination respiratory therapy management system creates a combined respiratory therapy prescription that can be executed by a combined respiratory therapy device to provide multiple coordinated respiratory therapies to a patient. The system can update the combined respiratory therapy prescription and implement the updates while the combined respiratory therapy device is in use. Some versions of the system provide additional features that allow the combined respiratory therapy prescriptions to be created, accessed, shared with other users, and performed by the combination respiratory therapy device in a customizable user-friendly and non-threatening way.

A therapeutic device for treating one or more conditions associated with a user's nasal cavities, sinuses, and/or ear canals includes a housing having an opening, an acoustic vibrator within the housing that is operable to provide an acoustic vibration to the user, a fan within the housing that is operable to provide a pressure to the user and a power supply that provides power to the acoustic vibrator and the fan. A mask is connected to the housing at the opening and includes a nasal interface appliable around the nose of the user, a nasal chamber in which the user's nostrils are located and an aperture through which the fan delivers the pressure.

An oscillating positive expiratory pressure system including an oscillating positive expiratory pressure device, an adapter coupled to the device, and a control module coupled to the adapter. The control module provides real time information about the use of the device, and provides feedback and storage of the information to improve the use thereof.

A system and method configured to control pressure during enhanced cough flow of a subject are provided. A pressure regulator is operated such that during an individual exhalation of the subject, the pressure regulator is toggled between a first mode in which a subject interface is closed such that substantially no gas is communicated with the airway of the subject there through and a second mode in which the subject interface is opened to cause a series of exsufflation events for the individual exhalation of the subject. The pressure relief valve is associated with the subject interface and configured to open and release gas out of the subject interface, responsive to pressure within the subject interface exceeding a predetermined threshold value so as to maintain the pressure within the subject interface within a predetermined pressure range during the enhanced cough flow.

Sleep apnea can be treated using positive airway pressure. Methods and systems for determining a level of airway obstruction allow beneficial adjustments to the level of expiratory positive airway pressure used to treat a subject.

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).

A pressure support methodology and system that utilizes at least two, and possibly all three, of information relating to (i) airway patency, i.e., the degree to which the patient's airway is open, (ii) the primary cause of the current sleep disordered breathing event, and (iii) the patient's response to previous pressure changes to automatically titrate pressure when presented with a sleep disordered breathing event. In another embodiment, pressure may be automatically titrated based solely on the primary cause of the sleep disordered breathing event.

An oscillating positive expiratory pressure apparatus having a housing defining a chamber, a chamber inlet, a chamber outlet, a deformable restrictor member positioned in an exhalation flow path between the chamber inlet and the chamber outlet, and an oscillation member disposed within the chamber. The deformable restrictor member and the oscillation member are moveable between an engaged position, where the oscillation member is in contact with the deformable restrictor member and an disengaged position, where the oscillation member is not in contact with the deformable restrictor member. The deformable restrictor member and the oscillation member move from the engaged position to the disengaged position in response to a first exhalation pressure at the chamber inlet, and move from the disengaged position to an engaged position in response to a second exhalation pressure at the chamber inlet.

A pressure indicator for a respiratory treatment device, the pressure indicator including an instrument for measuring pressures, a conduit configured to transmit a pressure within the respiratory treatment device to the instrument, and a pressure stabilizer orifice positioned within the conduit.

The present disclosure pertains to a method and system configured to in-exsufflate a subject by controlling the in-exsufflation pressure waveform. In some embodiments, the system comprises a pressure generator, a subject interface, one or more sensors, one or more processors, electronic storage, a user interface, and/or other components. The system is configured to assist the subject to loosen and/or expel secretions by inducing a percussive pressure waveform delivered to the subject during inhalation and/or exhalation. The system is configured to control the in-exsufflation therapy delivered to the subject without requiring regular manual setting and/or adjustment of pressures, pressure amplitudes, a frequency range, and/or other parameters of the percussive pressure waveform.
