背景脑成像技术在医疗保健模拟中的使用相对较少。然而，使用移动的，无线技术，如功能近红外光谱（fNIRS），正在成为一个有用的工具，用于评估模拟学习的独特需求。对于这项研究，这种成像技术被用来评估认知负荷在模拟学习events.MethodsThis研究发生在有关六个模拟活动，配对的相似性，并评估比较认知变化之间的三个任务对。这三个配对任务是：接收（1）面对面和（2）视频患者移交;在（1）二维和（2）360度视野中观察模拟场景;以及在模拟患者上（1）测量脉搏和（2）同时测量脉搏和呼吸率。结果在本研究中，fNIRS对常见模拟工具和场景中任务难度的变化敏感，随着认知负荷的增加，氧合血红蛋白浓度增加，脱氧血红蛋白浓度减少。研究结果证实了神经血红蛋白浓度标记物作为医疗保健模拟中认知变化的评估工具的有用性。研究结果表明，在模拟学习活动中，认知负荷在更复杂的认知任务中增加。因此，复杂性增加的任务表现会影响认知标记，需要增加脑力劳动。
BackgroundThe use of brain imaging techniques in healthcare simulation is relatively rare. However, the use of mobile, wireless technique, such as functional near-infrared spectroscopy (fNIRS), is becoming a useful tool for assessing the unique demands of simulation learning. For this study, this imaging technique was used to evaluate cognitive load during simulation learning events.MethodsThis study took place in relation to six simulation activities, paired for similarity, and evaluated comparative cognitive change between the three task pairs. The three paired tasks were: receiving a (1) face-to-face and (2) video patient handover; observing a simulated scene in (1) two dimensions and (2) 360 degrees field of vision; and on a simulated patient (1) taking a pulse and (2) taking a pulse and respiratory rate simultaneously. The total number of participants was n=12.ResultsIn this study, fNIRS was sensitive to variations in task difficulty in common simulation tools and scenarios, showing an increase in oxygenated haemoglobin concentration and a decrease in deoxygenated haemoglobin concentration, as tasks increased in cognitive load.ConclusionOverall, findings confirmed the usefulness of neurohaemoglobin concentration markers as an evaluation tool of cognitive change in healthcare simulation. Study findings suggested that cognitive load increases in more complex cognitive tasks in simulation learning events. Task performance that increased in complexity therefore affected cognitive markers, with increase in mental effort required.
