Abstract

Purpose: Clinical management decisions often rely on a patient’s SpO₂ level and desaturation rate. Limitations include that measurements depend on the averaging time (AVT) used, which is particularly relevant to sleep medicine, but has yet received little attention.
Methods: Cross-sectional review of studies reporting pulse oximeter saturation (SpO₂) measurements published in 5 leading sleep medicine journals. All papers published between 2017 and 2023 reporting SpO₂ measurements were screened regarding the AVT used.
Results: Of 193 papers identified, 151 were included; of these, only 9 studies mentioned the AVT, 4 of these were published in one journal. The AVT ranged from zero (beat-to-beat-mode) to 10s, with 3s being used most often (33.3%), followed by 2s (22.2%).
Conclusion: The AVT is only rarely mentioned in sleep medicine papers, despite its influence on sleep study results. Reported AVTs were heterogenous. Further research is warranted to set up guidelines for using or reporting the AVT.

Keywords: pulse oximetry, averaging time, oxygen saturation, desaturation, SpO₂, sleep medicine

脉搏氧饱和度测量的平均时间--五大睡眠医学期刊上发表的文章回顾

目的：临床管理决策通常依赖于患者的 SpO2 水平和失饱和率。其局限性包括测量结果取决于所使用的平均时间 (AVT)，这与睡眠医学尤其相关，但却很少受到关注：横向回顾 5 种主要睡眠医学期刊上发表的报告脉搏血氧饱和度（SpO2）测量结果的研究。对 2017 年至 2023 年间发表的所有报告 SpO2 测量结果的论文进行了筛选，以了解所使用的 AVT：在确定的 193 篇论文中，有 151 篇被收录；其中只有 9 项研究提到了 AVT，其中 4 项研究发表在一本期刊上。AVT 的范围从零（逐搏模式）到 10 秒，其中 3 秒使用最多（33.3%），其次是 2 秒（22.2%）：结论：尽管房室传导阻滞对睡眠研究结果有影响，但睡眠医学论文中很少提及房室传导阻滞。报告的 AVT 各不相同。关键词：脉搏血氧仪、平均时间、血氧饱和度、失饱和度、SpO2、睡眠医学

期刊介绍： Nature and Science of Sleep is an international, peer-reviewed, open access journal covering all aspects of sleep science and sleep medicine, including the neurophysiology and functions of sleep, the genetics of sleep, sleep and society, biological rhythms, dreaming, sleep disorders and therapy, and strategies to optimize healthy sleep. Specific topics covered in the journal include: The functions of sleep in humans and other animals Physiological and neurophysiological changes with sleep The genetics of sleep and sleep differences The neurotransmitters, receptors and pathways involved in controlling both sleep and wakefulness Behavioral and pharmacological interventions aimed at improving sleep, and improving wakefulness Sleep changes with development and with age Sleep and reproduction (e.g., changes across the menstrual cycle, with pregnancy and menopause) The science and nature of dreams Sleep disorders Impact of sleep and sleep disorders on health, daytime function and quality of life Sleep problems secondary to clinical disorders Interaction of society with sleep (e.g., consequences of shift work, occupational health, public health) The microbiome and sleep Chronotherapy Impact of circadian rhythms on sleep, physiology, cognition and health Mechanisms controlling circadian rhythms, centrally and peripherally Impact of circadian rhythm disruptions (including night shift work, jet lag and social jet lag) on sleep, physiology, cognition and health Behavioral and pharmacological interventions aimed at reducing adverse effects of circadian-related sleep disruption Assessment of technologies and biomarkers for measuring sleep and/or circadian rhythms Epigenetic markers of sleep or circadian disruption.
