The purpose of this study was to determine if a helicopter flight simulator could provide a useful educational platform by creating experiences similar to those encountered by actual flight nurses.
Flight nurse (FN) and non-FN participants completed a simulated emergency scenario in a flight simulator. Physiologic and psychological stress during the simulation was measured using heart rate and perceived stress scores. A questionnaire was then administered to assess the realism of the flight simulator.
Subjects reported that the overall experience in the flight simulator was comparable with a real helicopter. Sounds, communications, vibrations, and movements in the simulator most approximated those of a real-life helicopter environment. Perceived stress levels of all participants increased significantly from 27 (on a 0-100 scale) before simulation to 51 at the peak of the simulation and declined thereafter to 28 (P < .001). Perceived stress levels of FNs increased significantly from 25 before simulation to 54 at the peak of the simulation and declined thereafter to 30 (P < .001). Perceived stress levels of non-FNs increased significantly from 31 before simulation to 49 at the peak of the simulation and declined thereafter to 25 (P < .001). There were no significant differences in perceived stress levels between FNs and non-FNs before (P = .58), during (P = .63), or after (P = .55) simulation. FNs' heart rates increased significantly from 77 before simulation to 100 at the peak of the simulation and declined thereafter to 72 (P < .001).
The results of this study suggest that simulation of a critical care scenario in a high-fidelity helicopter flight simulator can provide a realistic helicopter transport experience and create physiologic and psychological stress for participants.
本研究旨在确定直升机飞行模拟器能否通过创造与实际飞行护士所经历的类似体验，提供一个有用的教育平台。
飞行护士（FN）和非飞行护士参与者在飞行模拟器中完成了一个模拟紧急场景。在模拟过程中，使用心率和感知压力分数来测量生理和心理压力。然后进行问卷调查，以评估飞行模拟器的逼真度。
受试者报告称，飞行模拟器中的总体体验与真实直升机相当。模拟器中的声音、通信、振动和运动最接近现实生活中的直升机环境。所有参与者的感知压力水平从模拟前的27（0 - 100分制）显著增加到模拟高峰期的51，随后下降到28（P <.001）。飞行护士的感知压力水平从模拟前的25显著增加到模拟高峰期的54，随后下降到30（P <.001）。非飞行护士的感知压力水平从模拟前的31显著增加到模拟高峰期的49，随后下降到25（P <.001）。在模拟前（P =.58）、模拟期间（P =.63）或模拟后（P =.55），飞行护士和非飞行护士的感知压力水平没有显著差异。飞行护士的心率从模拟前的77显著增加到模拟高峰期的100，随后下降到72（P <.001）。
本研究结果表明，在高保真直升机飞行模拟器中模拟重症护理场景可以提供逼真的直升机运输体验，并给参与者带来生理和心理压力。
