Metabolism-related respiratory parameters of Chinese young adults while sleeping: A pilot study on continuous monitoring during the night

We selected 20 young healthy Chinese adults (10 males and 10 females during their menstrual period, body mass index: 19.4–24.0 kg/m2) and continuously monitored their respiratory parameters during sleep (from 11:00 p.m. to 6:30 a.m. the next day). All data were recorded at 1-minute intervals, resulting in a total of 9,000 minutes of data analyzed. Results showed that nine parameters significantly decreased over sleep time. These parameters were oxygen uptake, CO2 emission rate, ventilation volume, respiratory rate, respiratory heat loss, body heat, metabolic rate, pulse rate, and core temperature. However, approximately 3.8 hours after falling asleep, the nine parameters tended to stabilize. Dynamic changes in respiratory parameters during sleep may lead to the unreliability of using averages to represent the entire night’s respiratory parameters. Considering the difficulty of data acquisition and the parameter requirements of the sleep human model, we have provided all respiratory parameters measured over time, only presented at 10-minute intervals.

本研究招募了20名健康年轻中国成年人（其中男性10名、月经周期内女性10名，体质量指数范围为19.4~24.0 kg/m²），并对其睡眠期间（当日23:00至次日6:30）的呼吸参数进行连续监测。所有数据以1分钟为间隔进行记录，最终累计可分析时长总计9000分钟。分析结果显示，9项参数在睡眠过程中呈显著下降趋势，具体包括摄氧量、二氧化碳排出率、通气量、呼吸频率、呼吸散热量、体热、代谢率、脉搏率及核心体温。但在入睡约3.8小时后，这9项参数趋于平稳。睡眠期间呼吸参数的动态变化，可能导致使用平均值表征整夜呼吸参数的结果不可靠。考虑到数据采集难度及睡眠人体模型的参数需求，本数据集提供了所有随时间采集的呼吸参数，仅以10分钟为间隔进行呈现。
