It has previously been shown that tidal volume and minute ventilation decrease in rats exposed to ozone . In this study, pre and post exposure thoracic breathing patterns were measured in Sprague-Dawley rats (n=9) exposed to 2 ppm O3 for three hours. The previous results of O3 exposure in rats were confirmed. In addition to confirming the results of the effects of O3 on tidal volume and minute ventilation, this study demonstrates a decrease in acceleration during the transition from deflation to inflation.
