[Assessment of working capacity in a group of subjects affected with obstructive respiratory disease (author's transl)].

Ventilatory function was studied by the authors in 43 subjects affected with obstructive respiratory disease. The research was performed both at rest and during two exercise tests -- 60 and 100 watts, respectively. The subjects were divided into three groups on the basis of tidal volume (at 30 1 ventilation) / vital capacity ratio. It was found that during muscular effort subjects with major impairment of spirometric indexes hypoventilated, whereas the opposite occurred in patients with lesser impairment. Moreover, subjects hyperventilating during muscular work were found to have brandypnea, whereas the opposite occurred in hyperventilating patients. It is suggested that progressing and worsening of obstructive emphysema lead to a relative hypoventilation during muscular work, which is due to an "inability" to increase the frequency of breathing.

[Maximal mid-exiratory flow (MMEF) in the evolution of the respiratory functional patter of silicosis. (author's transl)].

A follow up study of VC, FEV and MMEF was performed by the authors in forty silicotic patients, mainly in order to find out if MMEF were more sensitive than VC and FEV 1 IN detecting respiratory function impairment in the follow up of silicosis. In patients with moderate bronchial obstruction, a statistically significant difference was found between themean values of MMEF measured in two different instances: such a finding suggests a greater MMEF reduction in the early stages of silicosis. In 22 subjects with moderate respiratory function impairment (VC and FEV1 less than or equal 40% predicted values), MMEF was found to be, percentually, more decreased than FEV1: the difference was statistically significant. It is therefore concluded that MMEF changes in the follow up examination of silicosis are more sensitive than other functional indexes.
