重症监护病房(ICU)的患者可能会面临昼夜节律被打乱的风险。在一个干预研究项目中，在ICU房间里设置了一个循环照明系统，以支持患者的昼夜节律。第一部分通过照明体验问卷对不同照明环境下的两个房间的照明环境体验进行比较。结果显示，干预室的患者(n=48)在白天亮度感知方面的优势存在差异(p=0.004)。夜间，普通房间(n=52)光照变化较大(p=0.005)。第二部分旨在描述在配备了循环照明环境的房间中进行照明的体验。对19例患者进行访谈，结果按“动态照明环境”、“照明对患者陡度的影响”、“照明/灯光对昼夜节律的影响”和“照明平静”进行分类。大多数人有睡眠障碍的经历，一半的人有噩梦/幻觉和昼夜节律紊乱。几乎所有人都对循环的照明环境感到满意，这与日光一起支持了他们的昼夜节律。在夜间，实际的照明水平有助于患者和工作人员的联系，这带来了平静的感觉。(C)2015年提交人。由爱思唯尔有限公司出版。这是CC BY-NC-ND许可证(http://creativecommons.org/licenses/by-nc-nd/4.0/).下的一篇开放获取文章
Patients in an intensive care unit (ICU) may risk disruption of their circadian rhythm. In an intervention research project a cycled lighting system was set up in an ICU room to support patients' circadian rhythm. Part I aimed to compare experiences of the lighting environment in two rooms with different lighting environments by lighting experiences questionnaire. The results indicated differences in advantage for the patients in the intervention room (n=48), in perception of daytime brightness (p =0.004). In nighttime, greater lighting variation (p =0.005) was found in the ordinary room (n = 52). Part II aimed to describe experiences of lighting in the room equipped with the cycled lighting environment. Patients (n=19) were interviewed and the results were presented in categories: "A dynamic lighting environment", "Impact of lighting on patients' steep", The impact of lighting/lights on circadian rhythm" and The Lighting calms". Most had experiences from sleep disorders and half had nightmares/sights and circadian rhythm disruption. Nearly all were pleased with the cycled lighting environment, which together with daylight supported their circadian rhythm. In night's actual lighting levels helped patients and staff to connect which engendered feelings of calm. (C) 2015 The Authors. Published by Elsevier Ltd.
