This study was designed to address the following objectives: 1) To record the respiratory rate in a population of newborns and infants. 2) To verify the existence of a rhythm in each population group, as well as the organization and maturing process of these rhythms. 3) To determine the possible influence of environmental factors on these rhythms. The study population consisted of the following groups and ages: A) 1 day (21 cases); B) 7 (15 cases); C) 15 (10 cases); D) 30 (17 cases); E) 60 (17 cases); F) 90 (18 cases). Respiratory rate was continuously monitored and recorded, as well as environmental light, noise and temperature. Rhythmometric analysis of the data was done by simple Cosinor test and analysis of variance. The zero amplitude test showed statistically significant differences in the circadian rhythm of groups E and F (p < 0.005). An ultradian rhythm of 3 hours was detected in groups D and F. Environmental factors also showed a circadian rhythm. The appearance of an ultradian rhythm suggest the maturation in a rhythm. To evaluate physiological parameters, reference to time series must be considered.
1）记录新生儿和婴儿群体的呼吸频率。2）验证每个群体中节律的存在，以及这些节律的组织和成熟过程。3）确定环境因素对这些节律的可能影响。研究对象包括以下组群和年龄：A）1天（21例）；B）7天（15例）；C）15天（10例）；D）30天（17例）；E）60天（17例）；F）90天（18例）。持续监测和记录呼吸频率，以及环境光线、噪音和温度。通过简单的余弦分析和方差分析对数据进行节律分析。零振幅检验显示E组和F组的昼夜节律存在统计学显著差异（p < 0.005）。在D组和F组中检测到3小时的超日节律。环境因素也呈现出昼夜节律。超日节律的出现表明节律的成熟。为了评估生理参数，必须考虑时间序列。
