The activity of the right external abdominal oblique muscle, in relation to respiration, in newborn babies from 25 to 34 weeks' gestation was studied, using surface electrodes. Babies without respiratory difficulties showed no activity associated with respiration in these muscles. Grunting babies with respiratory disease showed pronounced activity during expiration. This activity continued when the babies were endotracheally intubated; if the babies were ventilated it sometimes disturbed the tidal ventilation delivered by the machines. When the baby expired during a ventilator inflation, so that gas came up the endotracheal tube against the inflating pressure, the abdominal oblique muscles contracted in 98% of the breaths.
使用表面电极研究了妊娠25至34周的新生儿右腹外斜肌与呼吸相关的活动。没有呼吸困难的婴儿在这些肌肉中未表现出与呼吸相关的活动。患有呼吸系统疾病的呼噜声婴儿在呼气时表现出明显的活动。当婴儿进行气管插管时，这种活动仍会持续；如果对婴儿进行通气，有时会干扰机器输送的潮气量通气。当婴儿在呼吸机充气期间呼气，导致气体逆着充气压力从气管导管中冒出时，98%的呼吸中腹斜肌会收缩。
