We report a case of a 54 years old man, treated with Methylphenidate (Ritalin) because of narcolepsy, who was referred with suspected vertebro-basilar insufficiency. In the hospital, apnoea during sleep attacks were observed. A polysomnography showed marked obstructive sleep apnoea with a disturbed hypnogram, but during the apnoeas the oxygen saturation only decreased by three to six percent. If a patient suspected for obstructive sleep apnoea has only small desaturations, an oximetry can be insensitive as the only "sleep examination", and a full polysomnography is recommended.
我们报告一例54岁男性患者，因发作性睡病接受哌甲酯（利他林）治疗，因疑似椎基底动脉供血不足前来就诊。在医院，观察到睡眠发作时出现呼吸暂停。多导睡眠图显示明显的阻塞性睡眠呼吸暂停，睡眠图紊乱，但呼吸暂停期间血氧饱和度仅下降3%至6%。如果怀疑阻塞性睡眠呼吸暂停的患者仅有轻微的血氧饱和度下降，作为唯一的“睡眠检查”，血氧测定可能不敏感，建议进行全面的多导睡眠图检查。
