Trachea noise biofeedback device to help reduce bronchospasm in asthmatics

Journal of Biomedical Engineering

Abstract

Evidence suggests that conscious control of bronchial smooth muscle tone may be possible. The asthmatic wheeze is caused mainly by broncho-constriction and it is hypothesized that if wheeze were consciously reduced, some bronchodilation would occur. Described here is a biofeedback device which records asthmatic tracheal noise with a microphone, and generates both an audio and visual display of the degree of wheeze sound intensity. The subject attempts to reduce wheeze using the device. Wrong information is also generated within the device so that the placebo effect can be investigated.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
