“…Commercially available (Listening Earth, Newstead, Queensland, Australia) nature sounds (e.g., water flowing, birds chirping) were used to overlay the videos, with different sounds used per video. Nature videos with corresponding sounds were chosen as the desired content based on a study conducted with individuals previously hospitalized in the ICU and nursing experts ( 14 ). Moreover, the choice is in line with the literature showing that nature can induce a relaxation response even when shown virtually ( 24–29 ).…”

“…Despite the known negative consequences of sensory overload and sensory deprivation, current prevention and treatment methods are limited. Sensory overload is currently prevented by decreasing or creating more targeted exposure to environmental factors, such as light and noise, while limiting interactions not related to patient care ( 3 , 14 ). This goal is achieved by using techniques such as the use of seclusion rooms or eye masks and ear plugs to promote sleep ( 3 , 15 , 16 ).…”

BackgroundSensory overload and sensory deprivation have both been associated with negative health outcomes in critically ill patients. While there is a lack of any clear treatment or prevention strategies, immersive virtual reality is a promising tool for addressing such problems, but which has not been repetitively tested in random samples. Therefore, this study aimed to determine how critically ill patients react to repeated sessions of immersive virtual reality.MethodsThis exploratory study was conducted in the mixed medical–surgical intermediate care unit of the University Hospital of Bern (Inselspital). Participants (N = 45; 20 women, 25 men; age = 57.73 ± 15.92 years) received two immersive virtual reality sessions via a head-mounted display and noise-canceling headphones within 24 h during their stay in the unit. Each session lasted 30-min and showed a 360-degree nature landscape. Physiological data were collected as part of the participants’ standard care, while environmental awareness, cybersickness, and general acceptance were assessed using a questionnaire designed by our team (1 = not at all, 10 = extremely).ResultsDuring both virtual reality sessions, there was a significant negative linear relationship found between the heart rate and stimulation duration [first session: r(43) = −0.78, p < 0.001; second session: r(38) = −0.81, p < 0.001] and between the blood pressure and stimulation duration [first session: r(39) = −0.78, p < 0.001; second session: r(30) = −0.78, p < 0.001]. The participants had a high comfort score [median (interquartile range {IQR}) = 8 (7, 10); mean = 8.06 ± 2.31], did not report being unwell [median (IQR) = 1 (1, 1); mean = 1.11 ± 0.62], and were not aware of their real-world surroundings [median (IQR) = 1 (1, 5); mean = 2.99 ± 3.22].ConclusionThe subjectively reported decrease in environmental awareness as well as the decrease in the heart rate and blood pressure over time highlights the ability of immersive virtual reality to help critically ill patients overcome sensory overload and sensory deprivation. Immersive virtual reality can successfully and repetitively be provided to a randomly selected sample of critically ill patients over a prolonged duration.

Virtual reality (VR) has experienced a remarkable evolution over recent decades, evolving from its initial applications in specific military domains to becoming a ubiquitous and easily accessible technology. This thorough review delves into the intricate domain of VR within healthcare, seeking to offer a comprehensive understanding of its historical evolution, theoretical foundations, and current adoption status. The examination explores the advantages of VR in enhancing the educational experience for medical students, with a particular focus on skill acquisition and retention. Within this exploration, the review dissects the applications of VR across diverse medical disciplines, highlighting its role in surgical training and anatomy/physiology education. While navigating the expansive landscape of VR, the review addresses challenges related to technology and pedagogy, providing insights into overcoming technical hurdles and seamlessly integrating VR into healthcare practices. Additionally, the review looks ahead to future directions and emerging trends, examining the potential impact of technological advancements and innovative applications in healthcare. This review illuminates the transformative potential of VR as a tool poised to revolutionize healthcare practices.

“…Before beginning to record any content, it is important to know what types of scenes should be recorded and their duration; this will depend on the overall purpose of the VR content. For example, if planning to use VR for relaxation purposes in patients with critical illness, the literature suggests that the duration should ideally be around 10-15 minutes [ 24 ]. On the other hand, if VR is to be used as a meditation tool to improve sleep in patients with critical illness, then a duration of 30 minutes may be better suited to that purpose [ 17 ].…”

The use of virtual reality (VR) stimulation in clinical settings has increased in recent years. In particular, there has been increasing interest in the use of VR stimulation for a variety of purposes, including medical training, pain therapy, and relaxation. Unfortunately, there is still a limited amount of real-world 360-degree content that is both available and suitable for these applications. Therefore, this tutorial paper describes a pipeline for the creation of custom VR content. It covers the planning and designing of content; the selection of appropriate equipment; the creation and processing of footage; and the deployment, visualization, and evaluation of the VR experience. This paper aims to provide a set of guidelines, based on first-hand experience, that readers can use to help create their own 360-degree videos. By discussing and elaborating upon the challenges associated with making 360-degree content, this tutorial can help researchers and health care professionals anticipate and avoid common pitfalls during their own content creation process.
