A total body plethysmograph is descirbed which was used to study thoracic gas volume (TGV) in infants and young children from birth to 2 1/2 years, and was suitable for use even in very sick babies. Normal TGV values were obtained in 42 studies of 35 healthy infants and young children, and 16 children with abnormal lung volume are described. TGV correlated well with length, weight, chest circumference, and age in the healthy infants. A low TGV was found in children with respiratory difficulties after cardiac and thoracic surgery, in respiratory distress syndrome of the newborn, and in association with pulmonary infection and chest cage abnormalities. Abnormally high TGV was most frequently seen in infants with small airways disease.
本文描述了一种全身体积描记器,该仪器用于研究从出生到2岁半婴幼儿的胸腔气体容积(TGV),甚至适用于病情非常严重的婴儿。对35名健康婴幼儿进行了42次研究,获得了正常的TGV值,并描述了16名肺容积异常的儿童。在健康婴幼儿中,TGV与身长、体重、胸围和年龄密切相关。在心脏和胸部手术后出现呼吸困难的儿童、新生儿呼吸窘迫综合征以及伴有肺部感染和胸廓异常的儿童中发现TGV较低。TGV异常高最常见于患有小气道疾病的婴儿。
