| Abstract: | The acceptable levels for added respiratory resistance of respiratory protective device ( RPD ) were determined in 56 healthy yo ing men under light physical loading conditions.The results showed that the maximal oral pressure swing (p) during a respiratory cycle and the extra respiratory work per unit ventilatiom(W/L) were highly correlated with both subjective and objective effects of added respiratory resistance.It is suggested that both P and W/L may be selected as an objective physiological index for breathing resistance standard,but p is applicable than W/L.Probit analysis indicates that 90% of a population breathing through RPD will experience no discomfort,if the p across the device (RPD) does not exceed 7.5cm H2O in light physical loading condition.The acceptable level suggested is relatively stringent as compared with those reported previously and is suited to light physical loading condition. |
