Conventional polysomnography (CPS) is a complex, costly procedure that is not widely available, meaning that it is difficult to apply it in patients suspected of having obstructive sleep apnea syndrome (OSAS). Various procedures have therefore been proposed for screening candidates for CPS. We studied the usefulness of visual analysis of nocturnal oximetry in 96 patients suspected of having OSAS. The OSAS diagnosis was confirmed by CPS in 67 (69.8%). Oximetry was positive in 70 cases. Sixty-one patients were positive by both oximetry and CPS, while 9 and positive oximetry results and a negative CPS. We conclude that nocturnal oximetry has a 91% sensitivity and 69% specificity for OSAS, with a positive predictive value of 87% and a negative predictive value of 77%. We believe that nocturnal oximetry may be a useful way of screening for OSAS, in order to decrease the number of CPS performed on patients without the disease.
传统多导睡眠图（CPS）是一种复杂且昂贵的检查方法，应用并不广泛，这意味着在疑似患有阻塞性睡眠呼吸暂停综合征（OSAS）的患者中难以实施。因此，人们提出了各种程序用于筛选CPS的候选对象。我们研究了对96例疑似患有OSAS患者进行夜间血氧饱和度测定的视觉分析的效用。通过CPS确诊OSAS的有67例（69.8%）。血氧饱和度测定结果阳性的有70例。61例患者的血氧饱和度测定和CPS结果均为阳性，9例患者血氧饱和度测定结果为阳性但CPS结果为阴性。我们得出结论，夜间血氧饱和度测定对OSAS的敏感性为91%，特异性为69%，阳性预测值为87%，阴性预测值为77%。我们认为夜间血氧饱和度测定可能是一种筛选OSAS的有用方法，以便减少对无该疾病患者进行的CPS检查数量。
