With the use of a B-scan phase-locked tracking system, 108 observations of fetal breathing were performed on 97 normal antenatal patients at term. One hundred thirty-three recorded segments of fetal breathing movements were obtained. Breath-to-breath variability was analyzed in 79 segments and expressed as a coefficient of variability. The mean coefficient of variability was 28.6% +/- 13.2%, and a histogram plot revealed a normal distribution. All fetuses had normal antepartum testing and all Apgar scores and neonatal courses were normal. The potential application of human fetal breathing variability as a test for fetal health is discussed.
使用B超锁相跟踪系统，对97名足月正常产前孕妇进行了108次胎儿呼吸观察。获得了133段记录的胎儿呼吸运动。对79段呼吸间变异性进行了分析，并以变异系数表示。平均变异系数为28.6%±13.2%，直方图显示呈正态分布。所有胎儿产前检查均正常，所有阿氏评分及新生儿病程均正常。本文讨论了人类胎儿呼吸变异性作为胎儿健康检测方法的潜在应用。
