• Description:
  An investigation was conducted to establish the role of the cardiorespiratory, metabolic and gas exchange analysis during exercise, to evaluate ceramic workers with the diagnosis of silicosis, and to correlate the results with the degree of dyspnea, the radiological alterations and the pulmonary function tests at rest. Forty three ceramics workers were examined who had the diagnosis of silicosis based on the occupational history of silica (14808607) dust exposure and on the radiographic features. Subjects were then separated into three groups based on radiographic features. Dyspnea was the most frequent symptom, being reported by 26 (61%) of the subjects, with similar distribution and intensity in the three groups. Spirometry was altered in 14 subjects, also similarly distributed in the three groups. Arterial blood gases at rest and during exercise were similar to the three groups. The evaluation of the silicotic patients during an exercise test revealed a certain number of incorrect predictions of working capacity based on the resting data. The authors conclude that the functional analysis during exercise can complete or modify the clinical, radiological and pulmonary function test analysis in evaluating the impairment of patients with pneumoconioses.
