It is desirable to screen snoring patients for obstructive sleep apnoea (OSA) prior to surgical treatment. We postulated that the addition of a sound profile would increase the value of overnight oxygen saturation (SaO2) as a screening method. Thirty-nine polysomnographic studies including sound level measured by calibrated meter were performed on snorers being considered for uvulopalato-pharyngoplasty (UPPP). Polysomnography showed an apnoea/hypopnoea index (AHI) > or = 15 per hour of sleep in seven subjects. Two experienced observers independently, without knowledge of other data, classified paper records of SaO2 alone and SaO2 plus sound level obtained during polysomnography as OSA 'unlikely', 'equivocal' or 'definite'. The addition of sound to SaO2 reduced the number of equivocal results from 14 to six and increased the number classified as 'definite' or 'unlikely'. The sensitivity of oximetry +/- sound increased as the threshold AHI used in the definition of OSA increased; addition of sound improved recognition of mild OSA without impairing specificity.
在对打鼾患者进行手术治疗之前，对其进行阻塞性睡眠呼吸暂停（OSA）筛查是很有必要的。我们推测，增加声音特征将提高夜间血氧饱和度（SaO2）作为一种筛查方法的价值。我们对39名考虑进行悬雍垂腭咽成形术（UPPP）的打鼾者进行了多导睡眠图研究，其中包括用校准仪测量的声级。多导睡眠图显示，7名受试者的呼吸暂停/低通气指数（AHI）每小时睡眠≥15次。两名经验丰富的观察者在不知道其他数据的情况下，独立地将多导睡眠图期间单独的SaO2记录以及SaO2加声级的纸质记录分类为OSA“不太可能”、“不明确”或“确定”。将声音添加到SaO2中后，不明确结果的数量从14个减少到6个，并增加了分类为“确定”或“不太可能”的数量。随着用于定义OSA的阈值AHI增加，血氧测定法±声音的敏感性也增加；添加声音可改善对轻度OSA的识别，而不会损害特异性。
