DESCRIPTION (provided by applicant): Development and Validation of a Virtual Airway Skill Trainer (VAST) Abstract "Airway management" is one of the most frequently performed procedures in operating rooms (OR), intensive care units (ICUs) and emergency departments (ED) to maintain air supply to the lungs. Yet, there exists no standardized curriculum or training regimen outside the age-old apprenticeship model. Hence, life- threatening scenarios, particularly those associated with the unexpected difficult airway (when an airway cannot be established using traditional methods), are seldom encountered during residency, limiting the opportunity of residents to train in the clinic. It is anticipated that a virtual reality (VR)-base trainer, with visual and haptic (touch) feedback, will be invaluable for training in airway management, allowing trainees to attain competence in a controlled environment with no risk to patients; customized learning; and real time feedback, mentoring and objective assessment. Existing VR-based simulators lack (1) realistic physics-based soft tissue modeling; (2) tissue response governed by models based on in vivo experiments; (3) realistic physical interfaces which can be easily altered to represent various external, and associated oropharyngeal anatomy of a patient known to cause difficulty with airway management [CaPe10] e.g., receding jaw, excessive soft tissue and large neck circumference; (4) cognitive skill training related to higher level mental functions associated with workload management, planning, coordination, and decision-making based on level of difficulty, in addition to psychomotor (hand-eye coordination and motor skills) skill training; and (5) clinical validation. The goal of this projec is to overcome these barriers and design, develop and validate the Virtual Airway Skill Trainer (VAST). A multidisciplinary team has been assembled to achieve the following Specific Aims: (SA1) Design and develop the Virtual Airway Skill Trainer (VAST) platform. Specifically, we will develop (1) physics-based computational models of human anatomy based upon in vivo experimental studies; (2) an immersive 3D high definition (HD) head mounted display (HMD) system to represent the clinical environment (OR/ICU/ED); and (3) an innovative bi-manual force feedback hardware interface with tactile matrix gloves that allows representation of various patient anatomies associated with the difficult airway. (SA 2) Develop simulation scenarios for endotracheal intubation (ETI) and cricothyrotomy (CCT) procedures within the VAST by integrating the computational models and experimental data generated in SA1. VAST will include real time feedback identifying errors; visual, auditory and haptic cues to guide the trainee; display of physiological consequence of complications; effects of alternate procedures and devices as well as automatic real time assessment of skill. (SA 3) Establish the validity of the VAST as a training tool by conducting experiments at Beth Israel Deaconess Medical Center (BIDMC) and Massachusetts General Hospital (MGH) in Boston to ensure that appropriate skills are being learnt on the VAST and performance measured on the VAST reflect the technical skills they intend to measure.

描述（由申请人提供）：虚拟气道技能培训师（广泛的）摘要“气道管理”的开发和验证是手术室（OR），重症监护病房（ICU）和急诊部（ED）中最常执行的程序之一，以维持肺部的空气供应。然而，在古老的学徒模型之外，没有标准化课程或培训方案。因此，在居住期间很少遇到生命的情况，特别是那些与意外困难气道相关的情况（当无法使用传统方法建立气道时），这限制了居民在诊所训练的机会。可以预料，具有视觉和触觉（触摸）反馈的虚拟现实（VR）培训师对于气道管理的培训将是无价的，允许受训者在受控环境中获得无风险的受控环境的能力；定制学习；以及实时反馈，指导和客观评估。现有的基于VR的模拟器缺乏（1）基于物理学的软组织建模； （2）基于体内实验的模型控制的组织反应； （3）可以轻松改变的现实物理界面，以代表已知因气道管理引起困难的患者的各种外部和相关的口咽解剖[Cape10] （4）除了精神运动（手眼协调和运动技能）以外，与工作量管理，计划，协调和决策相关的更高级别的心理功能有关的认知技能培训； （5）临床验证。该ProJec的目的是克服这些障碍和设计，开发和验证虚拟气道技能培训师（广大）。已经组装了一个多学科团队，以实现以下特定目标：（SA1）设计和开发虚拟Airway Skill Trainer（庞大）平台。具体而言，我们将基于体内实验研究基于人体解剖学的基于物理学的计算模型； （2）沉浸式3D高清（HD）头安装显示（HMD）系统，以表示临床环境（OR/ICU/ED）； （3）具有触觉矩阵手套的创新性双重反馈硬件接口，允许代表与困难气道相关的各种患者解剖学。 （SA 2）通过整合SA1中生成的计算模型和实验数据，开发了气管插管（ETI）和骨膜切开术（CCT）程序的模拟场景。大量将包括实时反馈识别错误；视觉，听觉和触觉提示指导学员；表现出并发症的生理后果；替代程序和设备的影响以及技能的自动实时评估。 （SA 3）通过在波士顿的贝丝以色列女执事医疗中心（BIDMC）和马萨诸塞州综合医院（MGH）进行实验，以确保在波士顿的贝丝公爵夫人医疗中心（BIDMC）进行实验，以确保在衡量其打算衡量的技术技能的广泛和广泛的技术技能上，以了解适当的技能。
