Abstract/OtherAbstract:
|
We investigated the effect on arterial blood oxygenation of exposure to 0.2 ppm of ozone in purified air for 2 hours with intermittent light exercise and heat stress. Similar exposures to purified air alone provided control data. In 12 healthy volunteers, blood gases were measured before and during exposure via an indwelling brachial cannula. Six of these subjects and 6 other subjects underwent separate similar studies in which "arterialized" earlobe capillary blood was sampled. Arterial Po2 and alveolar-arterial Po2 differences varied significantly among different experimental conditions, but the variability was similar in the presence or absence of ozone. Small significant variations in body temperature were observed; these did not appear to be sufficient to affect blood gas measurements substantially. Over-all, we found no evidence for an adverse effect of the exposure to ozone on arterial oxygenation. |
