(author)This study investigates how cognitive performance is affected by the combination of two stressors that are operationally relevant for helicopter pilots: heat load and hypobaric hypoxia. Fifteen participants were exposed to: 1) no stressors, 2) heat load, 3) hypobaric hypoxia and 4) combined heat load and hypobaric hypoxia. Hypobaric hypoxia (13...article 2023

Wingelaar-Jagt, Y.Q. (author), Bottenheft, C. (author), Riedel, W.J. (author), Ramaekers, J.G. (author)Background: Fatigue remains an important factor in major aviation accidents. Stimulants may counteract fatigue's adverse effects, with modafinil as a promising alternative to caffeine. However, the effect of a single dose of modafinil after a limited period of sleep deprivation remains unknown. Aims: This study aims to determine the effect of...article 2022

Linssen, L. (author), Landman, A. (author), van Baardewijk, J.U. (author), Bottenheft, C. (author), Binsch, O. (author)Real-time physiological stress monitoring would be a relevant addition to virtual reality (VR) training for high-risk professions, such as the military. VR is highly suitable for the implementation of such monitoring due to the controlled environment and the already used wearables. However, physiological stress measurements suffer from...article 2022

Binsch, O. (author), Bottenheft, C. (author), Landman, A. (author), Roijendijk, L. (author), Vermetten, E.H.G.J.M. (author)The current study explores whether different stressors in a virtual reality (VR) military training scenario cause increases in physiological stress. This would validate the use of VR simulation for stress training, as well as the physiological monitoring of trainees for educational purposes. Military cadets (n = 63) performed a patrol scenario ...article 2021

Bottenheft, C. (author), Brouwer, A.M. (author), Stuldreher, I. (author), Groen, E. (author), van Erp, J. (author)Effects of stressors on cognitive task performance have primarily been studied in isolation, and little is known about the combined effects of two or more stressors. This study examined how a metabolic stressor (skipping breakfast) and a sensory stressor (noise) affect cognitive task performance in isolation and combined. In addition to...article 2021

Traversari, A.A.L. (author), van Heumen, S.P.M. (author), van Tiem, F.L.J. (author), Bottenheft, C. (author), Hinkema, M.J. (author)Background: The effectiveness of an airflow system in preventing entrainment of particles carrying micro-organisms from the periphery of an operating room (OR) or instrument layup room (ILR) is affected by many variables. It is suspected that differences in the design of the systems affect the effective protection ratio (EPR): the ratio of the...article 2019

Pennings, H.J.M. (author), Bottenheft, C. (author), van de Boer-Visschedijk, G.C. (author), Stubbé, H.E. (author)Purpose: Informal learning is seen as the most important way to acquire and develop the skills and competencies required for work. The Dutch Defence organisation (DDO) aims to use the opportunities for development of employees that informal learning offers better and is looking for suitable interventions. Four possible interventions to improve...article 2019

Oprins, E. (author), Mol, D. (author), Bottenheft, C (author)Helicopter aircrew from Royal Netherlands Air Force (RNLAF) get Helicopter Underwater Egress Training (HUET) in order to be prepared for escaping the aircraft when ditching into water. Besides knowledge and skills how to escape, self-confidence is an important learning goal in HUET, especially because the underwater events are experienced as...public lecture 2019

Binsch, O. (author), Wilschut, E.S. (author), Arns, M. (author), Bottenheft, C. (author), Valk, P.J.L. (author), Vermetten, H.G.J.M. (author)There is a growing interest in the application of psychophysiological signals in more applied settings. Unidirectional sensory motor rhythm-training (SMR) has demonstrated consistent effects on sleep. In this study the main aim was to analyze to what extent participants could gain voluntary control over sleep-related parameters and secondarily...article 2018

(author)Background: Switching off air handling systems in operating theaters during periods of prolonged inactivity (eg, nights, weekends) can produce a substantial reduction of energy expenditure. However, little evidence is available regarding the effect of switching off the air handling system during periods of prolonged inactivity on the air quality...article 2016

Schreuder, E.J.A. (author), Lebesque, L.H.E.M. (author), Bottenheft, C. (author)The main aim of this research was to identify the impact of design characteristics (DCs) of a patient room on self-reported patient well-being. Background: This knowledge enables the construction of healing environments focusing on DCs that maximize well-being. Six themes were identified in literature that create healing environments: spatial...article 2016

Traversari, A.A.L. (author), Bottenheft, C. (author), Louman, R. (author), van Heumen, S.P.M. (author), Böggeman, J. (author)Background: Operating lamps are often seen as the most disruptive factors within the protective area in the operating theater (OT). The effect of the operation lamps (with different shapes) should be demonstrated in an OT by trial, since research on the effects of the lamps is still limited. Objectives: The main aim of this study was to...article 2016
