Reusable elastomeric air-purifying respirators: Physiologic impact on health care workers	2010-03-01		.txt	text/plain	2995	140	46	Compared with controls, the EAPR resulted in significant decreases in breathing rate at both work rates and significantly increased tidal volume at the 1.7-mph work rate; otherwise, there were no statistically significant differences in measured physiological variables (Tables 1 and 2) There were no significant differences in mean mixed inhalation/exhalation respirator dead space carbon dioxide concentrations at 1.7 mph and 2.5 mph (P 5 .61) or respirator dead space oxygen concentrations at 1.7 mph or 2.5 mph (P 5 .80) ( Table 2 ). The study data indicate that the use of an EAPR by healthy HCWs, over 1 hour at work rates associated with the health care environment, was associated with statistically significant decreases in the breathing rate at 1.7 mph (P 5 .02) and 2.5 mph (P 5 .03) that was compensated by a significant increase in the tidal volume at 1.7 mph (P 5 .009) and nonsignificant increase at 2.5 mph (P 5 .14) compared with controls (Table 3) .	./cache/cord-314206-caxz025z.txt	./txt/cord-314206-caxz025z.txt
