The criteria of hypopnea recommended by the American Academy of Sleep Medicine until 2012 was 3% desaturation and 50% decline in the signal amplitude. The recommended and alternative criteria for hypopnea were determined as 3% desaturation accompanied by a 30% decline in the signal amplitude and 4% desaturation accompanied by a 30% decline in the amplitude by the 2013 update of the guideline was published by the American Academy of Sleep Medicine in 2012. The objective of our study was to investigate to what degree scoring of hypopneas has great importance in the diagnosis and severity grading of obstructive sleep apnea syndrome according to different criteria.
The present study was designed as a retrospective study in which the results of the polysomnography of 62 patients were recorded after evaluation according to 3 different hypopnea criteria. Criteria 1, criteria 2, and criteria 3 were accepted as a 3% drop in SaO2 accompanied by a 30% decline in the amplitude, as a 4% drop in SaO2 accompanied by a 30% decline in the amplitude, and as a 3% drop in SaO2 accompanied with a 50% decline in the amplitude, respectively.
Statistically significant differences were determined between criteria 1 and criteria 2, criteria 1 and criteria 3, and criteria 2 and criteria 3 regarding the numbers of hypopneas.
For the same polysomnography, evaluations with different accepted hypopnea criteria cause different polysomnography results.
美国睡眠医学会在2012年之前推荐的呼吸浅慢标准为血氧饱和度下降3%且信号幅度下降50%。美国睡眠医学会在2012年发布的指南2013年更新版中，将呼吸浅慢的推荐标准及替代标准确定为血氧饱和度下降3%且信号幅度下降30%，以及血氧饱和度下降4%且信号幅度下降30%。我们研究的目的是根据不同标准调查呼吸浅慢的评分在阻塞性睡眠呼吸暂停综合征的诊断和严重程度分级中具有多大的重要性。
本研究设计为一项回顾性研究，根据3种不同的呼吸浅慢标准对62例患者的多导睡眠图结果进行评估并记录。标准1、标准2和标准3分别被定义为血氧饱和度下降3%且幅度下降30%、血氧饱和度下降4%且幅度下降30%、血氧饱和度下降3%且幅度下降50%。
在呼吸浅慢次数方面，标准1与标准2、标准1与标准3、标准2与标准3之间存在统计学显著差异。
对于同一多导睡眠图，采用不同的呼吸浅慢接受标准进行评估会导致不同的多导睡眠图结果。
