Abstract
Minor, but statistically significant, differences in oxygen saturation measured by pulse oximetry were noted between N95 filtering facepiece respirators with and without an exhalation valve and one model of an clastomeric air-purifying respirator worn by healthcare workers over one hour at two low work rates. Pulse oximetry detemtinations at the earlobe were significantly greater than concurrently obtained fingertip oximetry values, but the absolute differences were small and would presumably not be of practical significance. The use of respiratory protective equipment by healthy healthcare workers over a one hour period is not likely to result in any clinically significant oxygen desaturations.
