Measurements of tidal flow, volume, and oesophageal pressure were recorded on a group of 8 severely preterm infants with periodic respiration. Analysis of the flow trace for evidence of cardiac artefact, and the tidal volume trace to identify at what point of the tidal cycle apnoea starts, indicated that upper airways obstruction was associated with about half these attacks. It is surmised that this is produced by glottic closure.
对一组8名患有周期性呼吸的重度早产儿进行了潮气量、潮流量和食管压力测量。分析流量曲线以寻找心脏伪差的证据，并分析潮气量曲线以确定呼吸暂停在潮气量周期的哪个点开始，结果表明，约一半的发作与上呼吸道阻塞有关。据推测，这是由声门关闭引起的。
