A respiratory therapy apparatus includes a rocker mechanism (101, 110, 111, 112) that provides an oscillating resistance to expiration. The apparatus also includes an air entrainment arrangement (200) at its air inlet (3) having a ring orifice (214) connected via a gas inlet (4) to a source (119) of oxygen at elevated pressure. The oxygen emerging around the ring orifice (214) entrains ambient air and supplies this as a continuous flow of respiratory gas to the patient interface (2) to provide a positive airway pressure.

Disclosed are biofeedback methods and devices suitable for providing biofeedback useful for helping a user control an own breathing, for example, to help in inducing deep breathing, and such biofeedback devices further comprising a dispenser for dispensing an inhalable substance.

An oscillating positive expiratory pressure system including an oscillating positive expiratory pressure device having a chamber, an input component in communication with the chamber, wherein the input component is operative to sense a flow and/or pressure and generate an input signal correlated to the flow or pressure, a processor operative to receive the input signal from the input component and generate an output signal, and an output component operative to receive the output signal, and display an output.

A vibratory respiratory therapy device (100) has a valve element (11) on a rocker arm (12) that opens and closes an opening (10) during exhalation through the device and thereby generates sound. A mobile phone (20) with a microphone (21) picks up the sound generated and has a processor (22) that converts the sound signal into a sound energy signal in order to measure its frequency. The processor (22) computes a measure of pressure in the device (10) by multiplying the detected frequency by a fixed factor and adding a fixed constant to the product. The pressure data is used to monitor patient use of the device.

A breathing equipment training device and a method for breathing training using a breathing equipment training device. The breathing equipment training device includes a shell and a diaphragm. The shell includes a first opening and a second opening, the first opening configured to be inserted into a breathing opening in a mask to form a connection with the breathing opening of the mask, and the second opening configured to be exposed to ambient air. The diaphragm is positioned in an inner cavity of the shell about the second opening, and configured to impede airflow into the shell through the second opening.
