[Importance of ergooxytensiometry in the evaluation of dust exposure and of patients with lung silicosis].

After retrospective evaluation of numerous expertises of patients exposed to dust with and without silicosis the high value of the arterial partial oxygen pressure and of the ergooxytensiometry in the estimation of the cardiorespiratory functional breadth is explained. On an average in patients with silicosis III and silicotuberculosis, respectively, more frequently a respiratory insufficiency is found than in patients exposed to dust with lower stages of silicosis or without clue to the presence of a silicosis. In the individual case there is no firm relation between the x-ray-morphological findings and the result of the ergooxytensiometry. The roentgenological stage of silicosis does not allow a conclusion to the loss of function, on the contrary, the frequently existing bronchitis in patients exposed to dust plays an important part in the development of the disturbances of the pulmonary function.
