目的 探讨呼气末二氧化碳分压(pressure of end-tidal carbon dioxide concentration,PETCO2)的监测在阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者整夜多道睡眠图(PSG)监测中的应用及意义.方法 对38例OSAHS患者行整夜同步PSG和PETCO2监测,将PETCO2波形耦合到PSG中,观察记录PETCO2波形特点和数值,并与PSG相关指标行相关性分析.结果 睡眠期间呼吸平稳状态下PETCO2呈现梯形波,呼吸暂停时波形表现为一直线,低通气时呼气末平台的缩短或消失.非快动眼睡眠期、快动眼睡眠期以及整夜总睡眠时间的PETCO2平均值与呼吸暂停低通气指数及微觉醒指数呈负相关趋势(r值-0.458～-0.688,P值均＜0.01),与最低及夜间平均动脉血氧饱和度呈正相关趋势(r值0.604～0.674,P值均＜0.01).结论 PETCO2的监测可应用于PSG,睡眠期间PETCO2的平均值在一定程度上能反映OSAHS患者呼吸紊乱的严重程度.

Objective The purpose of this study was to investigate the end-tidal carbon dioxide concentration(PETCO2)monitoring coupling in polysomnography for patients with obstructive sleep apnea hypopnea syndrome(OSAHS)during sleep.Methods PETCO2 was sampled through an Oral-Nasal Cannula and measured using micro-stream capnometer.Capnometer was calibrated according to the manufacturer instructions and integrated into the standard polysomnographic recordings.Thirty-eight consecutive patients underwent overnight polysomnography(PSG)were synchronously monitored PETCO2.All variables were recorded continuously and transferred to a computer for analysis.Results PETCO2 numeric values and waveform were displayed in real time on the PSG epoch.The mean PETCO2 of wake,non-rapid eye movement,rapid eye movement and total sleep time were negatively correlated with apneahypopnea index and arousal index(r were-0.458--0.688,P ＜ 0.01),were positively correlated with mean arterial oxygen saturation(SaO2)and lowest SaO2(r were 0.604-0.674,P ＜ 0.01).Conclusions The study provides preliminary data showing that PETCO2 potentially can be used in continuous monitoring of OSAHS patients.PETCO2 can indicate the severity of OSAHS.
