摘要
声学体积描记仪已被开发用于提供早产儿(1.5-3.0公斤)的常规全身体积测量。它在50赫兹附近工作，并由带限25赫兹的跨度噪声激励。激发、测量、分析和环境均由计算机控制，以提高体积测定的准确性、速度和客观性。性能测试产生的体积测量结果的平均误差(±SD)为0.77±0.66%，体积分别为2880和2130 cm3。10，在20至30分钟的时间内，对14名婴儿进行了一分钟的体积测量。平均密度为1.061±0.028 g cm - 3，体重为1294 ~ 2025 g。
Pre-term infant volume measurements by acoustic plethysmography
An acoustic plethysmograph has been developed to provide routine total body volume measurements of pre-term (1.5–3.0 kg) infants. It operates near 50 Hz and is excited by band-limited 25 Hz span noise. Excitation, measurement, analysis, and environment are computer controlled for greater accuracy, speed, and objectivity in volume determinations. Performance tests produced volume measurements with a mean per cent error (± SD) of 0.77 ± 0.66% for two phantoms with volumes of 2880 and 2130 cm3. Ten, one-minute volume measurements were obtained for 14 infants over a 20 to 30 min period. Their mean density was 1.061 ± 0.028 g cm−3 and their weight ranged from 1294 to 2025 g.
