UNASSIGNED: Forty students and healthcare providers performed a simulated pediatric life support scenario, consisting of a chest compression task and a ventilation task, while wearing eye-tracking glasses. Skill Reporter software measured chest compression (CC) quality and Neo Training software measured ventilation quality. Main eye-tracking parameters were ratio [the number of participants who attended a certain area of interest (AOI)], dwell time (total amount of time a participant attended an AOI), the number of revisits (how often a participant returned his gaze to an AOI), and the number of transitions between AOIs.
UNASSIGNED: The most salient AOIs were infant chest and ventilation mask (ratio = 100%). During CC task, 41% of participants also focused on ventilation bag and 59% on study nurse. During ventilation task, the ratio was 61% for ventilation bag and 36% for study nurse. Percentage of correct CC rate was positively correlated with dwell time on infant chest (p = 0.044), while the overall CC quality was negatively correlated with dwelling outside of pre-defined task-relevant AOIs (p = 0.018). Furthermore, more dwell time on infant chest predicted lower leakage (p = 0.042). The number of transitions between AOIs was unrelated to CC parameters, but correlated negatively with mask leak during ventilations (p = 0.014). Participants with high leakage shifted their gaze more often between ventilation bag, ventilation mask, and task-irrelevant environment.
UNASSIGNED: Infant chest and ventilation mask are the most salient AOIs in pediatric basic life support. Especially the infant chest AOI gives beneficial information for the resuscitation provider. In contrast, attention to task-irrelevant environment and frequent gaze shifts seem to harm the quality of care.
■40名学生和医疗保健提供者进行了模拟儿科生命支持方案,由胸部按压任务和通气任务组成,戴着眼球追踪眼镜.SkillReporter软件测量胸部按压(CC)质量,NeoTraining软件测量通气质量。主要眼动追踪参数是比率[参加某个感兴趣区域(AOI)的参与者人数],停留时间(参与者参加AOI的总时间),重访的次数(参与者多久将目光转向AOI),以及AOI之间的转换数量。
■最明显的AOIs是婴儿胸部和通气面罩(比例=100%)。在CC任务期间,41%的参与者还关注通气袋,59%关注研究护士。在通风任务期间,通气袋的比例为61%,研究护士的比例为36%.正确CC率的百分比与婴儿胸部的停留时间呈正相关(p=0.044)。而总体CC质量与在预定义的任务相关AOI之外的居住呈负相关(p=0.018)。此外,婴儿胸部停留时间越长,泄漏越少(p=0.042)。AOI之间的转换次数与CC参数无关,但与通气期间的面罩泄漏呈负相关(p=0.014)。高渗漏的参与者更频繁地在通气袋之间转移他们的视线,通风面罩,与任务无关的环境。
■婴儿胸部和通气面罩是儿科基本生命支持中最重要的AOI。特别是婴儿胸部AOI为复苏提供者提供了有益的信息。相比之下,关注与任务无关的环境和频繁的目光转移似乎会损害护理质量。
