In this study we investigated whether the diagnosis of sleep apnoea syndrome (SAS), based on night-time polysomnography (NPSG), can be predicted or excluded by a one-hour daytime polysomnography (DPSG). The results of 306 NPSGs were compared with DPSGs, which were performed the day before. Treated patients were excluded. In the 89 patients with SAS (Apnoea index (AI)>/=5) 59 showed apnoeas during the DPSG and 30 did not. In the 217 without SAS 25 showed apnoeas daring DPSG and 192 did not. Sensitivity for detecting SAS was 66%, the specificity was 88%, the positive predictive value (PPV) 70% and the negative predictive value (NPV) 86%. For relevant SAS (AI>/=10) the NPV would be 95%. We conclude that the one-hour DPSG is not sufficient for diagnosing or excluding SAS with certainty. It can be used to make the presence of relevant SAS unlikely.
在本研究中，我们调查了基于夜间多导睡眠图（NPSG）诊断的睡眠呼吸暂停综合征（SAS）能否通过一小时的日间多导睡眠图（DPSG）来预测或排除。将306例NPSG的结果与前一天进行的DPSG结果进行比较。已接受治疗的患者被排除在外。在89例SAS患者（呼吸暂停指数（AI）≥5）中，59例在DPSG期间出现呼吸暂停，30例未出现。在217例无SAS的患者中，25例在DPSG期间出现呼吸暂停，192例未出现。检测SAS的敏感性为66%，特异性为88%，阳性预测值（PPV）为70%，阴性预测值（NPV）为86%。对于相关SAS（AI≥10），NPV将为95%。我们得出结论，一小时的DPSG不足以确定诊断或排除SAS。它可用于使相关SAS的存在不太可能。
