Respiratory Aid Device
A system is described for stimulating the chest wall of a subject to reduce breathlessness. The system includes a respiration sensor (3) operable to generate an output signal dependent on respiration of the subject; a stimulation device (7) operable to stimulate the chest wall of the subject; and a controller (5) arranged to monitor the output signal and to activate operation of the stimulation device dependent on the output signal. The system provides in-phase stimulation of intercostal muscles during respiration. The stimulation device may apply a mechanical vibration to the patient's chest wall. The controller controls the frequency of the applied vibration.
