[Bodyplethysmographic analysis in patients with silicosis (author's transl)].
Pulmonary airway resistance was measured in patients with silicosis and in normal subjects using a volume-constant bodyplethysmograph. Values of total resistance RT were compared with spirometric ventilation parameters, oxygen tension during steady-state-exercise and arterial blood pressure. The analysis shows a significant relationship between status of silicosis and the degree of resistance. Resistance values were found enhanced also in comparison with a decrease of vital capacity and FEV1 and with an increase of residual volume and arterial blood pressure.
