In the current study the modality-shift paradigm was applied to examine attention deficits in sleep-apnea patients. The reaction times of ipsi- and crossmodal light and sound stimuli were measured on 34 patients presenting symptoms of sleep-apnea. Some of the simple reaction times of ipsimodal (light-light; sound-sound) and crossmodal (light-sound; sound-light) stimuli correlated with mean or with minimal oxygen saturation, but did not correlate with the frequency or duration of obstructive apneas and hypopneas. However, results are different if the amount of modality-shift effect is taken into consideration. Significant correlations were found for the maximal duration of obstructive apneas and hypopneas as well as for mean oxygen saturation.
在当前研究中，采用模态转换范式来检查睡眠呼吸暂停患者的注意力缺陷。对34名有睡眠呼吸暂停症状的患者测量了同侧和跨模态光与声刺激的反应时间。同侧模态（光-光；声-声）和跨模态（光-声；声-光）刺激的一些简单反应时间与平均或最低血氧饱和度相关，但与阻塞性呼吸暂停和呼吸不足的频率或持续时间无关。然而，如果考虑模态转换效应的量，结果则有所不同。发现阻塞性呼吸暂停和呼吸不足的最长持续时间以及平均血氧饱和度之间存在显著相关性。
