The pressure and volume changes associated with the first breath were measured in 17 healthy term babies, using oesophageal balloons and a reverse plethysmograph. 5 babies expanded their lungs with less than --20 cmH2O (--2 kPa). The characteristic opening pressure pattern previously described was seen in only one baby, whose initial volume change was an expiratory one. It is concluded that opening pressures greater than 10 cmH2O (0.96 kPa) are rarely seen in term healthy infants.
使用食管气囊和反向体积描记器,对17名足月健康婴儿进行了与第一次呼吸相关的压力和体积变化测量。5名婴儿在小于-20 cmH2O(-2 kPa)的压力下扩张肺部。之前描述的特征性开放压力模式仅在一名婴儿中出现,其最初的体积变化是呼气性的。得出的结论是,足月健康婴儿很少出现大于10 cmH2O(0.96 kPa)的开放压力。
