妊娠相关的加速代谢和氧化应激可能改变呼出的挥发性化合物模式（“呼吸纹”）。电子鼻可以区分“呼吸纹”与不同disorders.Objective：这是第一个研究评估的“呼吸纹”在怀孕during pregnancy.Material and methods：130名妇女参加了我们的研究（78怀孕与52非怀孕）。呼吸样本进行处理的电子鼻和分析，使用主成分analysis.Results：孕妇和非孕妇之间的呼出气模式的显着差异（p = 0.001）。结论：妊娠引起的呼出气的变化，需要考虑当孕妇呼吸系统疾病进行呼气测试。
Context: Pregnancy-linked accelerated metabolism and oxidative stress may alter the exhaled volatile compound pattern ("breathprint"). Electronic noses can distinguish "breathprints" associated with different disorders.Objective: This is the first study assessing alterations in "breathprint" during gestation.Material and methods: 130 women participated in our study (78 pregnant vs. 52 non-pregnant). Breath samples were processed by an electronic nose and analyzed using principal component analysis.Results: Significant differences were found in exhaled breath pattern between pregnant and non-pregnant women (p = 0.001).Conclusion: Pregnancy-induced changes in exhaled gases need to be considered when pregnant women with respiratory disorders carry out breath tests.
