本研究的目的是表征清醒的健康人在休息条件下的呼吸波动。具体来说，我们使用艾伦因子和色散分析来测试呼吸次数、呼吸周期和呼吸幅度的波动是否是分形的或随机的。结果可归纳如下。在所有三个参数的波动是分形的9个科目。有4名受试者，其中只有呼吸次数和振幅的波动是分形的，三名受试者，其中只有呼吸次数的波动是分形的，和两名受试者，其中只有呼吸次数和呼吸周期的波动是分形的。其余两名受试者的三个参数随机波动。这些数据表明，呼吸次数，呼吸周期和呼吸幅度的分形波动是由单独的过程控制。
The present study was designed to characterize respiratory fluctuations in awake, healthy humans under resting conditions. Specifically, we used Allan factor and dispersional analysis to test whether the fluctuations in breath number, respiratory period, and breath amplitude were fractal or random in nature. The results can be summarized as follows. Fluctuations in all three parameters were fractal in nine subjects. There were four subjects in whom only the fluctuations in breath number and amplitude were fractal, three subjects in whom only fluctuations in breath number were fractal, and two subjects in whom only fluctuations in breath number and respiratory period were fractal. Fluctuations in the three parameters occurred randomly in the remaining two subjects. The data suggest that fractal fluctuations in breath number, respiratory period, and breath amplitude are controlled by separate processes.
