PURPOSE
Clinical management decisions often rely on a patient's SpO 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 (SpO) measurements published in 5 leading sleep medicine journals. All papers published between 2017 and 2023 reporting SpO 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.
目的
临床管理决策通常依赖于患者的血氧饱和度（SpO）水平和去饱和率。其局限性在于测量结果取决于所使用的平均时间（AVT），这在睡眠医学中尤为重要，但尚未得到足够关注。
方法
对在5种主要睡眠医学期刊上发表的报告脉搏血氧饱和度（SpO）测量值的研究进行横断面综述。筛选2017年至2023年间发表的所有报告SpO测量值的论文，查看其使用的AVT。
结果
在识别出的193篇论文中，纳入了151篇；其中，只有9项研究提到了AVT，其中4项发表在同一本期刊上。AVT范围从零（逐搏模式）到10秒，最常使用的是3秒（33.3%），其次是2秒（22.2%）。
结论
尽管AVT会影响睡眠研究结果，但在睡眠医学论文中很少被提及。报告的AVT存在异质性。有必要进行进一步研究以制定使用或报告AVT的指南。
