Visuo-acoustic stimulation that helps you to relax: A virtual reality setup for patients in the intensive care unit

Abstract After prolonged stay in an intensive care unit (ICU) patients often complain about cognitive impairments that affect health-related quality of life after discharge. The aim of this proof-of-concept study was to test the feasibility and effects of controlled visual and acoustic stimulation i...

The VR setup consisted of a head-mounted display in combination with an eye tracker and sensors to assess vital signs.
