||Farmers have an above-average frequency of bronchitis and bronchial asthma attributable to the inhalation of specific organic dusts. As in other professions, filters of respiratory devices do not offer complete protection. This was demonstrated in 26 farmers suffering from occupational asthma, who were challenged by exposure to work-related dust, first without and then, about 20 weeks later, with the respiratory device. The increases in airway resistance and thoracic gas volume were statistically significant in both challenges, but 50-80% smaller when respiratory devices in the second challenge. This experiment shows that the use of a respirator in farmers suffering from occupational asthma reduces the development of bronchial obstruction but does not prevent it.
