The present disclosure pertains to a system configured to enhance deep sleep in a subject during positive airway pressure therapy. A pressure generator is configured to generate a pressurized flow of breathable gas for delivery to an airway of the subject. Sensors are configured to generate output signals conveying information related to breathing of the subject. One or more hardware processors are configured to cause the pressure generator to generate the pressurized flow of breathable gas in accordance with a positive airway pressure therapy regime based on the information in the output signals; determine sleep stages of the subject based on the information in the output signals; and responsive to the sleep stages indicating the subject is in deep sleep, cause the pressure generator to adjust the pressurized flow of breathable gas to deliver a stimulus to the subject, the stimulus configured to enhance deep sleep in the subject.

A positive exhalation pressure device increases the pressure gradient in the airways, thereby increasing oxygen saturation levels and decreasing the severity of hypoxia. Various embodiments of the device may be inserted into the nasal and/or oral cavities, or configured as mask devices covering the nasal and/or oral cavities. In some embodiments, the resistance of the device may be varied.

A combination positive airway pressure (PAP) or continuous positive airway pressure (CPAP) and resuscitation system and related methods. The systems can be well-suited for use in providing CPAP therapy for a neonate or infant patient, with the ability to also provide resuscitation therapy at a peak inspiratory pressure (PIP) as needed or desired without switching to another system or switching the patient interface. The system can include an expiratory pressure device capable of regulating a positive end expiration pressure (PEEP) of the system, which preferably can also induce pressure oscillations relative to a mean PEEP.

An apparatus for oxygenation and/or CO2 clearance of a patient. The apparatus comprising: a flow source or a connection for a flow source for providing a gas flow, a gas flow modulator, a controller to control the gas flow. The controller is operable to: receive input relating to heart activity and/or trachea gas flow of the patient, and control the gas flow modulator to provide a varying gas flow with at least two oscillating components. One oscillating component has a frequency based on the heart activity and/or trachea flow of the patient. One oscillating component has a frequency to: promote bulk gas flow movement, or promote mixing.

A respiratory treatment device includes a housing, an inlet configured to receive air into the housing, an outlet configured to permit air to exit the housing, and a flow path defined between the inlet and the outlet. A restrictor member positioned along the flow path that is configured to move between a closed position, where the flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted. A vane in communication with the flow path rotatable in response to the flow of air along the flow path is configured to move the restrictor member between the closed position and the open position. A protrusion extends in to the housing to limit movement of the restrictor member from the closed position to the open position.

Various embodiments are described herein for a controller for controlling the operation of a breathing assistance device that provides breathing assistance to a user. The controller comprises a processor that generates a respiratory index value that is determined during a current monitoring time period to detect a respiratory failure, or predict the respiratory failure when at least one PSG signal is measured. The respiratory index value is compared to a threshold to determine if the control signal needs to be updated to reduce or eliminate respiratory failure that the user is currently experiencing or to prevent a predicted respiratory failure from occurring.

A respiratory therapy apparatus is operable to deliver multiple types of therapy to a patient. The apparatus includes a main housing and a nebulizer tray that selectively attaches to a bottom of the main housing. The apparatus also includes a filter housing unit having an antenna surrounding a pneumatic passage and a transponder chip coupled to the antenna. The main housing has also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

Systems for evaluating the respiratory function of an individual using forced oscillation technique (FOT) oscillometry include a blower controlled so as to apply FOT pressure oscillations on top of a low amplitude offset pressure. A controller continually adjusts the rotational speed of the blower to maintain a targeted time-varying pressure profile in the breathing air provided to the patient.

A processor acquires a first radiographic image and a second radiographic image obtained by irradiating a subject, into which a tracheal tube has been inserted, with radiation in different directions, derives a three-dimensional position of a distal end of the tracheal tube in the subject on the basis of a position of the distal end of the tracheal tube in each of the first radiographic image and the second radiographic image, derives a three-dimensional position of a bronchial bifurcation in the subject on the basis of a bronchial bifurcation position in each of the first radiographic image and the second radiographic image, and determines insertion of the tracheal tube into an esophagus on the basis of the three-dimensional position of the distal end of the tracheal tube and the three-dimensional position of the bronchial bifurcation.

Respiratory therapy apparatus includes an oscillating expiratory therapy device and pressure and flow sensors in the patient inlet connected to supply signals to a processor. The processor includes artificial intelligence software to correlate the output signals with prescribed values and control a feedback device that prompts the patient accordingly to adjust use of the device as necessary. The feedback device may be of a visual, audible or tangible kind. The processor may also automatically adjust a setting dial of the therapy device by means of an actuator.
