| Resumen |
Data obtained from tests to which 7 miners had been subjected: ECG and rheopulmonogram changes, energy metabolism, arterial pressure, lung capacity and respiration, analysis of alveolar air, gas exchange and energy expenditure. Changes were found in pulmonary circulation, indicating increased tension of the pulmonary vessels, hyperfunction of the right heart and probable hypervolaemia in the pulmonary circulation. Workers' respiration is increased and aggravates the load on the right heart and stress in the pulmonary circulation, which is more pronounced in winter. This excess pulmonary activity is probably caused by microclimatic and other conditions in deep mineworkings, and also reflects the workers' adaptation to the climate. |
