Auditory middle-latency evoked potentials (AMEP) were recorded in 10 subjects with predominantly central sleep apnea. AMEP were recorded during: waking; non-rapid eye movement (non-REM) sleep between apneic episodes; first half of apneas; and second half of apneas. Latencies of vertex positive peaks Po and Pa were determined, and the effect of the apnea phase on these latencies was evaluated. The latencies measured did not reveal chronic or acute functional abnormality of central auditory structures, which may result from or cause apneic episodes during non-REM sleep. The normalcy and stability of AMEP during apneic sleep may indicate effective compensatory mechanisms in central auditory structures. Alternatively, the lack of changes may result from the variability of AMEP, which may obscure small functional changes.
对10名主要患有中枢性睡眠呼吸暂停的受试者记录了听觉中潜伏期诱发电位（AMEP）。在以下期间记录AMEP：清醒状态；呼吸暂停发作之间的非快速眼动（非REM）睡眠；呼吸暂停的前半段；以及呼吸暂停的后半段。测定头顶正峰Po和Pa的潜伏期，并评估呼吸暂停阶段对这些潜伏期的影响。所测得的潜伏期未显示中枢听觉结构存在慢性或急性功能异常，而这种异常可能是由非快速眼动睡眠期间的呼吸暂停发作引起或导致的。呼吸暂停睡眠期间AMEP的正常性和稳定性可能表明中枢听觉结构存在有效的代偿机制。或者，缺乏变化可能是由于AMEP的变异性所致，这种变异性可能掩盖了微小的功能变化。
