多导睡眠图（ PSG）是一种监测睡眠和醒觉机体多种生理活动的技术，是诊断睡眠呼吸暂停综合征（ SAS）的标准手段。本院已进行PSG监测3000余例，本文结合本院2012年1-10月随机选取的22例患者PSG监测结果，对PSG实际操作及分析中的若干问题进行探讨。PSG监测前患者需充分准备，传感器应正确安置；用脑电电极Fp1A2、Fp2A1替代C3A2、C4A1进行睡眠结构的分析，对睡眠各期的睡眠结构无影响（ P .0.05）。另外，PSG监测结果应进行人工校正，因为人工校正前后清醒期、Ⅰ期睡眠、深睡眠、快速动眼期的睡眠结构间有差异（ P<0.05）；人工校正后呼吸暂停低通气指数（ AHI）、最长呼吸暂停时间、最长低通气时间与校正前比较亦有差异（ P<0.05），但血氧饱和度间无差异（P .0.05）。总之，一份良好的睡眠记录及各项指标的正确分析可获得准确的PSG监测结果。

Polysomnography( PSG)is a technology for monitoring multiple physiological activities of body in sleeping and waking. PSG is the standard method to diagnose sleep apnea syndrome(SAS). More than 3 000 cases of PSG have been mo-nitored in our hospital. The article discusses several issues of operating PSG by analyzing the PSG results of 22 cases of SAS admit-ted to our hospital from January to October in 2012. Before performing PSG,patients should be well prepared and the sensors must be exactly connected. With electrodes Fp1A2 and Fp2A1 instead of C3A2 and C4A1 in analyzing sleep architecture,there was no statistically significant difference in the sleep architecture(P .0. 05). The lucid interval,sleep phaseⅠ,deep sleep and rap-id eye movement sleep showed statistically significant differences before and after manual adjustment(P<0. 05). Apnea hypop-nea index( AHI),longest apnea time,and longest hypopnea time also showed statistically significant differences before and af-ter manual adjustment ( P <0. 05 ), but there was no statistically significant difference in oxygen saturation ( P . 0. 05 ) . A clear sleep recording and careful manual analysis help get perfect PSG results.
