Apparent central apnoea (absent breathing movements) detected by monitoring movement of the thoracic wall was compared with simultaneous detection by abdominal wall movement. Eighteen infants provided one or more 24 hour recording of heart rate (electrocardiography), thoracic respiration (transthoracic impedance), and abdominal wall movement (pressure sensitive capsule distortion). Detection of true apnoea, recognition of artefact, and measurement of the duration of true apnoea were all improved when two channels of respiratory monitoring were used in combination. We recommend that any study purporting to observe breathing patterns by indirect recording of respiratory movement will be more reliable if more than one channel of respiratory movements is recorded simultaneously. Further, in infants no estimation of duration of central apnoea can be made on the basis of either a transthoracic impedance record alone or an abdominal wall movement sensor alone. Comparison of findings among studies using different single channel recordings are unlikely to be meaningful.
通过监测胸壁运动检测到的明显中枢性呼吸暂停（呼吸运动缺失）与同时通过腹壁运动检测的结果进行了比较。18名婴儿提供了一份或多份24小时的心率（心电图）、胸式呼吸（经胸阻抗）和腹壁运动（压敏胶囊变形）记录。当将两个呼吸监测通道结合使用时，真正呼吸暂停的检测、伪差的识别以及真正呼吸暂停持续时间的测量均得到了改善。我们建议，如果同时记录多个呼吸运动通道，那么任何旨在通过间接记录呼吸运动来观察呼吸模式的研究将更加可靠。此外，对于婴儿，仅基于经胸阻抗记录或仅基于腹壁运动传感器都无法对中枢性呼吸暂停的持续时间进行估计。使用不同单通道记录的研究之间的结果比较不太可能有意义。
