Participants increased their exercise work rate to achieve a PIFR of greater than 100 1/minute.
Ten subjects (eight men and two women) completed the study (Table 1) Mean PIFR at rest was 27.9 (SD 9.23) 1/minute and with exercise 119.9 (SD 20.04) 1/minute.
Calculated Fi[O.sub.2] is highest, for all delivered gas flow rates, when breathing at rest through the nose, and lowest when exercising to a PIFR of >90 1/minute.
Data at each measurement time point for each parameter (PIFR and [FIF.sub.25-75]) were confirmed for normality using the Kolmogorov-Smirnov and the Sharpiro-Wilk tests with the level of significance set at P=0.05.
FEF25-75%, PEFR and PIFR also decreased significantly in the workers exposed more than 10 years.
