任何重症监护室（ICU）的主要任务是为危重病人提供高质量的护理和休养的环境。然而，通常情况下，密集的环境，往往是繁忙的，混乱的，嘈杂的，可能会导致相反的结果。受到噪音、灯光和其他干扰的过度刺激的患者通常会因睡眠不足而变得僵硬。医学和护理研究表明，睡眠不足会对病人产生不利影响。因此，在神经icu中制定了一个安静的时间计划，以减少噪音和光线水平，最终目标是允许睡眠。安静时间，一段减少可控噪音和光线的时间，每天进行两次，与昼夜节律一致。该研究包括50例神经icu患者，其中35例在白天观察，15例在夜间观察。在安静时间之前、期间和之后，在多个地点测量了噪音和光线水平。每半小时记录一次患者的睡眠行为，从安静时间前半小时开始，直到安静时间后30分钟。根据对患者的多次测试和重复测量进行调整后的数据分析显示，白班安静时间的噪音和光照水平明显较低。此外，患者更有可能在白班安静时间被观察到睡觉。
The primary mission of any intensive care unit (ICU) is to provide critically ill patients with high-quality care and an atmosphere in which to recuperate. However, all too often, the intensive environment, which is often busy, chaotic, and noisy, may contribute to just the opposite. Patients overstimulated with noise, lights, and other distractions often stiffer from sleep deprivation. Research in medicine and nursing has shown that sleep deprivation can have detrimental effects on an ailing patient. Therefore, a quiet time program was developed in the neuro-ICU to reduce noise and light levels, with the ultimate goal to allow sleep. Quiet time, a period of reduced controllable noise and light, took place twice daily coinciding with circadian rhythms. The study included 50 neuro-ICU patients, 35 observed during day hours and 15 observed during night hours. Noise and light levels were measured at multiple locations before, during, and after quiet time hours. Patients' sleep behavior was recorded every half hour, beginning 1/2 hour before quiet time until 30 minutes after. Analysis of data, adjusted for multiple testing and repeated measures on patients, demonstrated significantly lower noise and light levels during day shift quiet time. In addition, patients were significantly more likely to be observed sleeping during day shift quiet time hours.
