The usefulness of daytime polysomnography (DPSG) in the diagnosis of sleep apnea syndrome (SAS) is examined. Diagnostic use was investigated by conducting DPSG of two different time periods (Group M, 11.00-14.00 h, and Group A, 15.00-18.00 h). The subjects were 30 patients (28 men and two women; mean age, 54.0 years). Nocturnal polysomnography (NPSG) and DPSG were investigated by comparing indices of sleep, apnea index (AI) and arterial oxygen saturation (SaO2). There was no significant difference among these indices but there was a significant positive correlation between NPSG and DPSG in all variables related to sleep apnea. Moreover, there was no significant difference in the frequency of each type of apnea between NPSG and DPSG in either group. These findings suggest that DPSG is useful not only in diagnosing SAS but in evaluating its severity.
研究了日间多导睡眠图（DPSG）在睡眠呼吸暂停综合征（SAS）诊断中的实用性。通过对两个不同时间段进行DPSG（M组，11:00 - 14:00时；A组，15:00 - 18:00时）来研究其诊断用途。受试者为30例患者（28名男性和2名女性；平均年龄54.0岁）。通过比较睡眠指标、呼吸暂停指数（AI）和动脉血氧饱和度（SaO2）来研究夜间多导睡眠图（NPSG）和DPSG。这些指标之间无显著差异，但在所有与睡眠呼吸暂停相关的变量中，NPSG和DPSG之间存在显著正相关。此外，两组中NPSG和DPSG之间每种类型呼吸暂停的频率均无显著差异。这些发现表明，DPSG不仅有助于诊断SAS，还能评估其严重程度。
