| Abstract |
Mouth-occlusion pressure (P0.1) and ventilatory responses during carbon dioxide (CO2) rebreathing and exercise on a bicyle ergometer, were examined in 12 patients with silicosis and 8 healthy subjects. Similar values were observed for P0.1 at rest and P0.1 response to PCO2 during rebreathing in both groups. Patients had significantly higher values of P0.1 during the 30 W-ergometer exercise test, and these were comparable to the P0.1 of the healthy subjects during the 90W exercise test and with the maximum values obtained during CO2 rebreathing. Despite the elevated P0.1, the increased ventilatory responses during rebreathing and exercise were lower in patients than in healthy subjects. |
