Abstract
Objective: 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.
Material and methods: 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.
Results: 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.
Conclusion: For the same polysomnography, evaluations with different accepted hypopnea criteria cause different polysomnography results.
目的:截至2012年，美国睡眠医学会推荐的低通气标准为3%的去饱和度和50%的信号幅度下降。美国睡眠医学会(American Academy of Sleep Medicine)于2012年发布了2013年更新的指南，推荐和替代的低通气标准确定为3%的去饱和伴30%的信号幅度下降和4%的去饱和伴30%的幅度下降。本研究的目的是探讨根据不同的标准，低呼吸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的重要程度。材料与方法:本研究为回顾性研究，根据3种不同的低通气标准评估62例患者的多导睡眠图结果。标准1、标准2和标准3分别被接受为SaO2下降3%伴随幅度下降30%，SaO2下降4%伴随幅度下降30%，SaO2下降3%伴随幅度下降50%。结果:诊断标准1与诊断标准2、诊断标准1与诊断标准3、诊断标准2与诊断标准3关于低呼吸次数的差异有统计学意义。结论:对于相同的多导睡眠图，采用不同公认的低通气标准评价会导致不同的多导睡眠图结果。
期刊介绍：
Turkish Thoracic Journal (Turk Thorac J) is the double-blind, peer-reviewed, open access, international publication organ of Turkish Thoracic Society. The journal is a quarterly publication, published on January, April, July, and October and its publication language is English. Turkish Thoracic Journal started its publication life following the merger of two journals which were published under the titles “Turkish Respiratory Journal” and “Toraks Journal” until 2007. Archives of both journals were passed on to the Turkish Thoracic Journal. The aim of the journal is to convey scientific developments and to create a dynamic discussion platform about pulmonary diseases. With this intent, the journal accepts articles from all related scientific areas that address adult and pediatric pulmonary diseases, as well as thoracic imaging, environmental and occupational disorders, intensive care, sleep disorders and thoracic surgery. Clinical and research articles, reviews, statements of agreement or disagreement on controversial issues, national and international consensus reports, abstracts and comments of important international articles, interesting case reports, writings related to clinical and practical applications, letters to the editor, and editorials are accepted.
