DEMO: "Stayin' Alive": An Interactive Augmented - Reality CPR Tutorial
2018
Education is the Achilles heel of successful resuscitation in cardiac arrest. Therefore, we aim to contribute to the educational efficiency by providing a novel augmented-reality (AR) guided interactive cardiopulmonary resuscitation (CPR) "trainer". For this trainer, a mixed reality smart glass, Microsoft HoloLens, and a CPR manikin covered with pressure sensors were used. To introduce the CPR procedure to a learner, an application with an intractable virtual teacher model was designed. The teaching scenario consists of the two main parts, theory and practice. In the theoretical part, the virtual teacher provides all information about the CPR procedure. Afterward, the user will be asked to perform the CPR cycles in three different stages. In the first two stages, it is aimed to gain the muscle memory with audio and optical feedback system. In the end, the performance of the participant is evaluated by the virtual teacher
Projected AR-Based Interactive CPR Simulator
Lecture Notes in Computer Science, 2013
In this paper, we propose a new approach of a cardiopulmonary resuscitation (CPR) simulation system that exploits both AR-based visualization and embedded hardware sensing techniques. The proposed system provides real-time interactive visual feedback to the CPR trainee with the projected AR indicator plane that visualizes results of an interlocking signal of the trainee's actions using embedded sensors. This system also provides proper guidelines about the CPR trainee's posture by detecting a user's articular pose from a RGB-D camera in real-time. As implementation results, our system provides interactive feedback, that enabling more accurate and effective training experience to the trainee and more cost-effective rather than traditional CPR education training systems.

Background: Guidelines-based cardiopulmonary resuscitation (CPR) during in-hospital cardiac arrest is a significant predictor of survival, yet the quality of healthcare provider (HCP) CPR (e.g., nurses, physicians etc.) has been shown to be poor. Studies have found that providing HCPs with simulated CPR refresher trainings can improve their CPR quality, however, no studies have compared the use of an augmented reality (AR) CPR refresher training with a standard audiovisual (AV) feedback manikin to improve HCP training. Objectives: In our pilot study, HCPs were randomized to a refresher CPR simulation training with either our AR CPR training application (CPReality) or a standard AV feedback manikin. All subjects completed 2 min of CPR on their respective CPR training modalities, followed by an additional 2 min post-simulation CPR evaluation with no feedback. We hypothesized that the AR CPR training application would confer improved CPR quality defined as chest compression rate and depth compared with the standard AV feedback training. Results: Between January 2019 and May 2019, 100 HCPs were enrolled (50 in the CPReality cohort and 50 in the standard AV manikin cohort). The mean chest compression (CC) rate for all subjects during the intervention was 118 ± 15 cpm, and CC depth was 50 ± 8; post-intervention the CC rate was 120 ± 13 and CC depth was 51 ± 8. The mean CC rate for those trained with CPReality was 121 ± 3 compared with the standard CPR manikin training which was 114 ± 1 cpm (p < 0.006); CC depth was 48 ± 1 mm vs. 52 ± 1 (p = 0.007), respectively. Post-simulation CPR quality with no feedback showed a mean CC rate for the CPReality application at 122 ± 15 cpm compared with the standard CPR manikin at 117 ± 11 cpm (p = 0.09); depth was 49 ± 8 mm vs. 52 ± 8 (p = 0.095), respectively. In the post-survey, 79% of CPReality subjects agreed that the AR application provided a realistic patient presence compared with 59% (p = 0.07) of subjects in the standard CPR manikin cohort. Leary et al. Comparing CPR Augmented Reality vs. Standard Training Conclusions: In a randomized trial of an AR CPR training application compared with a standard CPR manikin training, the AR CPR application did not improve the quality of CPR performed during a CPR refresher training compared with the standard training in HCPs. Future studies should investigate the use of this and other digital technologies for CPR training and education.

Deaths due to heart diseases are a leading cause of death in Mexico. Cardiovascular diseases are considered a public health problem because they produce cardiorespiratory arrests. During an arrest, cardiac and/or respiratory activity stops. A cardiorespiratory arrest is rapidly fatal without a quick and efficient intervention. As a response to this problem, the VirtualCPR system was designed in the present work. VirtualCPR is a mobile virtual reality application to support learning and practicing of basic techniques of cardiopulmonary resuscitation (CPR) for experts or non-experts in CPR. VirtualCPR implements an interactive virtual scenario with the user, which is visible by means of employment of virtual reality lenses. User’s interactions, with our proposal, are by a portable force sensor for integration with training mannequins, whose development is based on an application for the Android platform. Furthermore, this proposal integrates medical knowledge in first aid, related to ...
Augmented Reality for Tactical Combat Casualty Care Training
2018
Combat Life Savers, Combat Medics, Flight Medics, and Medical Corpsman are the first responders of the battlefield, and their training and skill maintenance is of preeminent importance to the military. While the instructors that train these groups are exceptional, the simulations of battlefield wounds are extremely simple and static, typically consisting of limited moulage with sprayed-on fake blood. These simple presentations often require the imagination of the trainee and the hard work of the instructor to convey a compelling scenario to the trainee. Augmented Reality (AR) tools offer a new and potentially valuable tool for portraying dynamic, high-fidelity visual representation of wounds to a trainee who is still able to see and operate in their real environment. To enhance medical training with more realistic hands-on experiences, we are working to develop the Combat Casualty Care Augmented Reality Intelligent Training System (C3ARESYS). C3ARESYS is our concept for an AR-based ...
Augmented Reality in Cardiology
The Anatolian Journal of Cardiology, 2019
The augmented reality (AR) is an emerging technology that facilitates the comprehension of many situations that are difficult to understand otherwise. It is based on the superimposition of a virtual image on the real-world images. It is used as an assisting tool in areas of education, emergency, diagnosis, surgery and percutaneous interventions in cardiology, although all these areas are in their infancy period of using. In this review, the use of AR in cardiology is summarized with special reference to some studies. Augmented reality (AR) can be defined as "An enhanced version of reality where live direct or indirect views of physical realworld environments are augmented with superimposed computer-generated images over a user's view of the real-world, thus enhancing one's current perception of reality "(1). The AR is one component of the spectrum of extended reality, which includes virtual reality (VR), merged reality, mixed reality and AR. It differs from VR that, nothing in VR is real, while in AR, some virtual objects are implemented in real world environment. Merged and mixed realities are usually regarded as one and named as mixed reality, which are between VR and AR. "Augmented reality" has been firstly introduced as a term in 1990 by Caudell (2). He has used this technology in aviation industry to ensure adequate training experience. In AR, the user interacts with the virtual object, which is synchronously in conjunction with user's physical real environment. Therefore, users can see more than they can see without AR. The AR technology enables people to interact with 3D objects more easily, and therefore, decreases the cognitive load and enhances spatial skills (3). The AR technology also enables users to see some explanation about the situation at the same time and at the same perspective with the real world. (Fig. 1). There are four categories of AR (1): (1) Marker-based AR; (2) Markerless AR; (3) Projection-based AR; (4) Superimpositionbased AR. In marker-based AR, the AR is activated by a marker such as QR code, therefore needs a visual marker like camera. In markerless AR, frequently a GPS embedded in a device such as smartphone is used. The game of Pokemon-Go is an example of this type of AR. Projection-based AR send light to real world and enables interaction between the image and real world. Hologram
Development of a training tool for endotracheal intubation: Distributed Augmented Reality
Studies in health …, 2003
The authors introduce a tool referred to as the Ultimate Intubation Head (UIH) to train medical practitioners' hand-eye coordination in performing endotracheal intubation with the help of augmented reality methods. In this paper we describe the integration of a deployable UIH and present methods for augmented reality registration of real and virtual anatomical models. The assessment of the 52 degrees field of view optics of the custom-designed and built head-mounted display is less than 1.5 arc minutes in the amount of blur and astigmatism, the two limiting optical aberrations. Distortion is less than 2.5%. Preliminary results of the registration of a physical phantom mandible on its virtual counterpart yields less than 3mm rms. in registration. Finally we describe an approach to distributed visualization where a given training procedure may be visualized and shared at various remote locations. Basic assessments of delays within two scenarios of data distribution were conducted and reported. 16 hospital study conducted by the National Emergency Airway Registry between August 1997 and October 1998, out of 2392 recorded ETIs, 309 complications were reported, with 132 of these difficulties resulting from intubation procedures . Many anesthesiologists believe that the most common reason for failure of intubation is the inability to visualize the vocal cords. In fact, failed intubation is one of the leading causes of anesthesia-related morbidity and mortality . Thus, there is international concern for the need to extensively train paramedics in pre-hospital emergency situations .
A Distributed Augmented Reality System for Medical Training and Simulation
Augmented Reality (AR) systems describe the class of systems that use computers to overlay virtual information on the real world. AR environments allow the development of promising tools in several application domains. In medical training and simulation the learning potential of AR is significantly amplified by the capability of the system to present 3D medical models in real-time at remote locations. Furthermore the simulation applicability is broadened by the use of real-time deformable medical models.
An Affordable, Virtual Reality Based Training Application for Cardiopulmonary Resuscitation
International Journal on Advances in ICT for Emerging Regions (ICTer), 2021
In Medical science, proficiency in Cardiopulmonary Resuscitation (CPR) is considered as a vital skill for physicians. For training CPR, medical professionals use mechanical manikin which has some drawbacks when it comes to the realism of the simulation and the feedback of performance. This paper presents a Virtual Reality (VR) based solution to address some of these shortcomings. The approach here is augmenting the mechanical manikin with VR using HTC Vive, Leap Motion Controller, and a glove. To test the acceptance of this solution, a user-based evaluation was carried out. 85.7% of the users who have participated in the evaluation have expressed their preference upon using VR in CPR training. Even though the overall evaluation depicts a neutral output, this study opens avenues for future research in combining VR into medical training processes.
