Impedance pneumography is potentially a non-invasive method of measuring infant tidal volumes. In order to evaluate the accuracy of impedance pneumography, eight healthy infants (weighing from 709 to 3506 grams) were randomly chosen and studied. Simultaneous measurements of tidal volumes were made by calibrated spirometry and by transthoracic impedance pneumography. The results were statistically compared. Transthoracic impedance pneumography provided a reliable estimate of tidal and minute volumes in these newborn infants.
阻抗式肺量计有可能成为一种测量婴儿潮气量的非侵入性方法。为了评估阻抗式肺量计的准确性，随机挑选并研究了八名健康婴儿（体重从709克至3506克）。通过校准后的肺量计和经胸阻抗式肺量计同时测量潮气量。对结果进行统计学比较。经胸阻抗式肺量计能够可靠地估算这些新生儿的潮气量和分钟通气量。
