Careful analysis of the EEG in obstructive sleep apnea (OSA) patients according to the Rechtschaffen and Kales (R & K) criteria indicates that obstructive apneas (OA) are more frequently observed during stage 1 and 2 sleep than during slow wave sleep. However it is also obvious that OA can be recognised during R & K wakefulness stage (St W). The purpose of the present study was to see whether further partition of R & K St W could define a wakefulness stage during which no apneas occur. Ten patients with predominantly OSA were studied (OA-Index 20 +/- 5). Patients EEG were scored according to classic R & K and to modified criteria which further divided R & K St W. Three additional stages were defined (STW-a, STW-b, STW-c). The partitioning of STW of R & K allowed us to define a W-stage (STW-a) during which no apneas occur, and to identify alpha (STW-b) and drowsiness (STW-c) during which OA occur frequently.
根据 Rechtschaffen 和 Kales（R&K）标准对阻塞性睡眠呼吸暂停（OSA）患者的脑电图进行仔细分析表明，与慢波睡眠相比，在睡眠第1和第2阶段更频繁地观察到阻塞性呼吸暂停（OA）。然而，很明显在R&K清醒阶段（St W）也能识别出OA。本研究的目的是观察R&K St W的进一步划分是否能定义一个无呼吸暂停发生的清醒阶段。对10名主要为OSA的患者进行了研究（OA指数20±5）。根据经典的R&K标准以及进一步划分R&K St W的修改标准对患者的脑电图进行评分。定义了另外三个阶段（STW-a、STW-b、STW-c）。R&K的STW划分使我们能够定义一个无呼吸暂停发生的W阶段（STW-a），并识别出频繁发生OA的α阶段（STW-b）和嗜睡阶段（STW-c）。
