Using tunable white light, complete darkness, color-changing light, and an intuitive user interface, this team created a light/dark environment intended to help patients get to sleep, remain asleep, and sleep at the optimal time of day. Regular dark exposure is provided to maximize brain and body rest. Stakeholder comments from patients, parents, physicians, nurses, and patient advocates were used to inform the design and refine the system and control sequences after installation. Presenters will share the design, the bumps in the road, and the final results using video, still photos, and post-occupancy comments. They will then preview their future research agenda.


Learning Objectives

Identify design considerations for a dynamic light/dark environment to support circadian health while providing required illumination to deliver care. Understand how mediating disrupted sleep and metabolism can affect patient recovery. Gain knowledge of the co-design process and its effect on designing the lighting for a pediatric and cardiovascular ICU. Evaluate the benefits and perceived challenges of a circadian-supportive environment through feedback from physicians, nurses, and families.
