Reusable elastomeric air-purifying respirators: Physiologic impact on health care workers	2010-03-01		.txt	text/plain	3007	100	37	Furthermore, at the 2 work rates, the mean mixed inhalation/exhalation respirator dead space oxygen concentrations (17.85%, 17.81%, respectively) and respirator dead space carbon dioxide concentrations (2.50%, 2.47%, respectively) did not meet Occupational Health and Safety Administration ambient workplace standards (ie, ,19.5% is considered oxygen deficient; maximum 0.5% carbon dioxide as an 8-hour time weighted average), 22 although these standards apply to the workplace, not to respirators. Compared with controls (no respirator), significant decreases in the breathing rate at both work rates (P < .05) and increases in tidal volume at the lower work rate (P < .01) were noted with respirator use.	cache/cord-314206-caxz025z.txt	txt/cord-314206-caxz025z.txt
