Thermal comfort in operating theatres for different types of ventilation systems

Thermal comfort in operating theatres is a less addressed research component of the in-door environment in operating theatres. The air quality naturally gets most attention when considering the risk of surgical site infections. However, the importance of thermal comfort must not be underestimated. In this research, the current thermal comfort situation of staff members is investigated. Results show that the thermal comfort for the members of a surgical team is perceived as not optimal. Application of the PMV and DR models needs further attention when applied for operating theatres. For the investigated ventilation systems, the differences in thermal comfort outcomes are small.

A protocol for the implementation of new technology in a highly complex hospital environment

Medical equipment is implemented in highly complex hospital environments, such as operating rooms, in hospitals around the world. In operating rooms (ORs), technological equipment is used for surgical activities and activities in support of surgeries. The implementation of government policies in hospitals has resulted in varying implementation activities for (medical) equipment. These result in varying lead times and success rates. An integral and holistic protocol for implementation does not yet exist. In this study, we introduce a protocol for the implementation of (medical) equipment in ORs that consists of implementation factors and implementation activities. Factors and activities are based on data from a systematic literature review and an explorative survey among surgical support staff on factors for the successful implementation of technological and (medical) equipment in ORs. The protocol consists of five factors and related implementation activities: the establishment of a project plan, organisational preparation, technological preparation, maintenance, and training.

Alternative ventilation system for operating theaters: parameter study and full-scale assessment of the performance of a local ventilation system

A local operating theater ventilation device to specifically ventilate the wound area has been developed and investigated. The ventilation device is combined with a blanket which lies over the patient during the operation. Two configurations were studied: Configuration 1 where HEPA-filtered air was supplied around and parallel to the wound area and Configuration 2 where HEPA-filtered air was supplied from the top surface of the blanket, perpendicular to the wound area. A similar approach is investigated in parallel for an instrument table. The objective of the study was to verify the effectiveness of the local device. Prototype solutions developed were studied experimentally (laboratory) and numerically (CFD) in a simplified setup, followed by experimental assessment in a full scale mock-up. Isothermal as well as non-isothermal conditions were analyzed. Particle concentrations obtained in proposed solutions were compared to the concentration without local ventilation. The analysis procedure followed current national guidelines for the assessment of operating theater ventilation systems, which focus on small particles (<10 mm). The results show that the local system can provide better air quality conditions near the wound area compared to a theoretical mixing situation (proof-of-principle). It cannot yet replace the standard unidirectional downflow systems as found for ultraclean operating theater conditions. It does, however, show potential for application in temporary and emergency operating theaters

Implementing Medical Technological Equipment in the OR

from the Article: "Operating rooms (ORs) more and more evolve into high-tech environments with increasing pressure on finances, logistics, and a not be neglected impact on patient safety. Safe and cost-effective implementation of technological equipment in ORs is notoriously difficult to manage, specifically as generic implementation activities omit as hospitals have implemented local policies for implementations of technological equipment. )e purpose of this study is to identify success factors for effective implementations of new technologies and technological equipment in ORs, based on a systematic literature review. We accessed ten databases and reviewed included articles. )e search resulted in 1592 titles for review, and finally 37 articles were included in this review. We distinguish influencing factors and resulting factors based on the outcomes of this research. Six main categories of influencing factors on successful implementations of medical equipment in ORs were identified: “processes and activities,” “staff,” “communication,” “project management,” “technology,” and “training.” We identified a seventh category “performance” referring to resulting factors during implementations. We argue that aligning the identified influencing factors during implementation impacts the success, adaptation, and safe use of new technological equipment in the OR and thus the outcome of an implementation. The identified categories in literature are considered to be a baseline, to identify factors as elements of a generic holistic implementation model or protocol for new technological equipment in ORs."

Mixing realities: reflections on presence and embodiment in intermedial performance design of Blue Hour VR

Created for the 2019 Prague Quadrennial’s 36Q°, Blue Hour VR was a site-responsive mixed reality performative installation that placed the spectator, as experiencer, within a hybrid landscape of real- time three-dimensional computer graphics and 360-degree video. This article describes the design process, staging and experience of Blue Hour VR from the vantage point of its creators. Using a phenomenological perspective, the article discusses how Blue Hour VR staged presence and embodiment within an intermedial haptic experience. Blue Hour VR demonstrates how virtual reality technology can be harnessed by a mixed reality performance design, which includes both the material and virtual environment, creating a complex stratigraphy of intermedial textures and visual dramaturgies that co-exist inside, outside and in between perceptual realities. In doing so, the article aims to contribute to the limited body of work on mixed and virtual reality in the context of theatre and performance design.

Reflections on artist organisations international

The Artist Organisations International conference, organised by Florian Malzacher, Jonas Staal and Joanna Warsza, took place in Berlin’s HAU theatre from 9 to 11 January 2015. The organisers emphasised how it seems that more and more activist artists are creating organisational structures that increase the effectiveness of their artistic actions and productions, which also makes it possible for them to exert an influence on the ethical standards of the contexts in which they work. In this review we (dr. B. Straatman, dr. A. Coumans) present five important issues rising up out of this conference

Art as encounter

In this essay I will discuss the specific nature of art practices in which the artist and his audience are moving away from the more traditional relationship in which the artist merely displays his art in museums or public spaces. They consist of intimate and personal processes made possible by the grace of the artistic space that is separating itself from the coded space around it. In these practices the public takes on a different role than that of the passive spectator. The involvement of the public in what art is and can be becomes part of the experience. This turns art into something to be a part of rather than something that is simply handed over to you. More specifically, these art practices allow for a time and site-specific situated form of co-ownership, through which the artistic environment created by the artist becomes the condition for experiencing new ideas and insights. In relation to theatre, the French philosopher Jacques Rancière (1940-) writes in The Emancipated Spectator (2015) about “a theater without an audience” that “no longer tempts with its images but teaches the audience something that turns them into active participants rather than passive voyeurs”. (Rancière 2015: 9-10) These practices are not new. New is perhaps the shift of focus from public participation in processes of interaction towards developing a theatrical space that not only makes other types of expression possible, but also taking on other roles and with that, other perspectives. This notion will therefore be the main focus of this text.

Algorithmic Anxiety in Contemporary Art: A Kierkegaardian Inquiry into the Imaginary of Possibility

Over the past decade, a growing number of artists and critical practitioners have become engaged with algorithms. This artistic engagement has resulted in algorithmic theatre, bot art, and algorithmic media and performance art of various kinds that thematise the dissemination and deployment of algorithms in everyday life. Especially striking is the high volume of artistic engagements with facial recognition algorithms, trading algorithms and search engine algorithms over the past few years.The fact that these three types of algorithms have garnered more responses than other types of algorithms suggests that they form a popular subject of artistic critique. This critique addresses several significant, supra-individual anxieties of our decade: socio- political uncertainty and polarisation, the global economic crisis and cycles of recession, and the centralisation and corporatisation of access to online information. However, the constituents of these anxieties — which seem to be central to our experience of algorithmic culture — are rarely interrogated. They, therefore, merit closer attention.This book uses prominent artistic representations of facial recognition algorithms, trading algorithms, and search algorithms as the entry point into an exploration of the constituents of the anxieties braided around these algorithms. It proposes that the work of Søren Kierkegaard—one of the first theorists of anxiety—helps us to investigate and critically analyse the constituents of ‘algorithmic anxiety’.

Review ‘The Nature Spectacle’ by Jim Igoe

The Nature Spectacle: On Images, Money, and Conservation Capitalism by Jim Igoe is, as its Preface states, an ambitious book that seeks to make connections between diverse times and places. The preface also, in many ways, tells more about the background and intention of the book than its chapters do, tying together the author’s origins and motivation. Igoe recalls his childhood in St. Louis, Missouri, much of which he spent “in front of a television and at a neighborhood movie theatre” (p. XII), once watching a musical, which was “essentially an extended Chevrolet commercial set among the geysers of Yellowstone” (P. 109). It is the mix of such absurd and comical observations of commercialism merging with Nature, and much heavier criticism of the capitalist cult of economic growth, development, and also conservation that characterizes The Nature of Spectacle. Much of Igoe’s outdoor experiences were shaped by green spaces, created in St. Louis as part of commodity exhibits at the 1904 World’s Fair. The author admits to feeling both critical and nostalgic of those places that have merged (sub)urban aesthetics with that of industrially developed commercial “spaces” (p. XII) – important concepts that form a leitmotif throughout the book. https://doi.org/10.1080/03066150.2018.1488355 https://www.linkedin.com/in/helenkopnina/
