A system for stimulating body tissue may include a stimulation lead, sensors, and a control unit. The stimulation lead may include one or more energy sources. The control unit may include a processor and non-transitory computer readable medium, and an interface (e.g., touch screen interface) for receiving user inputs and communicating information to the user. The sensors may be configured to provide impedance measurements to the control unit. The control unit may calculate lung gas distributions and/or generate an image modeling lung gas distributions. Stimulation delivered by the stimulation may be adjusted based on the impedance measurements.

An oscillatory PEP therapy device (100) has valve (10) mounted at the end of a rocker arm (12) such that the valve is opened and closed during expiration through the device, thereby causing displacement of the rocker arm up and down. The housing (2) of the device (100) is transparent so that the camera (20) on a mobile phone (200) can be positioned to view displacement of the rocker arm (12) during use. The phone (200) is programmed to extract a signal indicative of the frequency of oscillation of the rocker arm (12) and this is displayed on the screen of the phone to provide feedback to the user.

Respiratory systems with a flow generator can provide bubble CPAP therapy by controlling the pressure of a flow of gas delivered to a patient. The controller of the respiratory system can control a motor speed of its flow generator so as to control the pressure of the flow of gas. The controller can also detect presence of bubbling and/or possible leaks in the gas pathway of the system. The respiratory system can include a high flow respiratory system.

A respiratory treatment device comprising at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, at least one chamber outlet configured to permit exhaled air to exit the at least one chamber, and an exhalation flow path defined between the chamber inlet and the at least one chamber outlet. A restrictor member positioned in the exhalation flow path is moveable between a closed position, where a flow of exhaled air along the exhalation flow path is restricted, and an open position, where the flow of exhaled air along the exhalation flow path is less restricted. A vane in fluid communication with the exhalation flow path is operatively connected to the restrictor member and is configured to reciprocate between a first position and a second position in response to the flow of exhaled air along the exhalation flow path.

Disclosed is a device for stimulating the tracheobronchial air of a patient suffering from an obstructive ventilatory disorder and able to modify the rheology of his tracheobronchial mucus, which includes a negative pressure generator, a physiological interface able to interface the device with the patient's respiratory apparatus, a connection pipe connecting the physiological interface to the negative pressure generator, and a control circuit capable of controlling the negative pressure generator, during the passive expiration phase, for the application of a succession of alternation of negative pressure and venting impulses with a determined frequency and a duty cycle determined during a first part of an expiration cycle and then a second frequency and a second duty cycle during a second part of the expiration cycle and to reiterate a defined number of expiration cycles.

Described herein is a respiratory care apparatus capable of performing multitude of therapy for secretion management and breath assistance therapy. The respiratory care apparatus comprises an electromechanical air router assembly (EARA) and an interfacing assembly. The EARA includes independent first and second pressure generating sources for assisted inhalation/insufflation and assisted exhalation/exsufflation process. The interfacing assembly includes a patient interface port and a patient interface tube. The interfacing assembly forms two pneumatically separate paths. The respiratory care apparatus is configured to generate alternate positive and negative pressure at the patient interface port for assisted inhalation/insufflation and assisted exhalation/exsufflation processes respectively. The assisted inhalation/insufflation and assisted exhalation/exsufflation processes are carried out independently through separate conduits/passages to reduce contamination and infection. Further, the respiratory care apparatus comprises a garment which oscillates due to alternate positive and negative pressure generation and provides therapy to the patient.

The invention provides a positive airway pressure therapy system comprising a positive pressure generation unit, adapted to generate a positive pressure airflow for provision to a subject, and an oscillatory pressure generation unit adapted to modulate the positive pressure airflow at a modulation frequency thereby imparting a frequency component to the positive pressure air flow. The oscillatory pressure generation unit is adapted to modulate the airflow during an exhalation phase of a breathing cycle of the subject.

A device is provided for controlling the nitric oxide levels within the lungs of a subject. The device comprises a detector for detecting the respiration cycle of the subject and a stimulator for applying an acoustic or vibratory stimulus to the subject. The stimulator is controlled in dependence on the detected respiration cycle. In particular, acoustic stimulation may be provided at the onset of inspiration. In this way, the nitric oxide flow can be controlled in a way to ensure that the paranasal nitric oxide is nearly fully inspired. This provides a higher nitric oxide concentration in the lung/alveoli.

A positive pressure ventilation (PPV) appliance module includes an adapter that couples to a port on an NIV mask and an appliance for performing a respiratory care procedure. The adapter is configured to form a PPV seal with the port of the PPV mask and also form a PPV seal with the appliance. The PPV appliance module allows clinicians to perform procedures through the NIV mask without disrupting the therapeutic pressure.

A method for guiding suction of an obstruction may comprise emitting sound waves from a sound generator into a tube, detecting returning acoustic reflections with at least one sound receiver, analyzing, using a processor, timings and amplitudes of the returning acoustic reflections to determine a location and size of an obstruction within the tube and a location of a tip of a suction catheter, and guiding the suction catheter to the obstruction.
