[Bio Times] According to the '2020 Sudden Cardiac Arrest Survey Statistics' released by the Korea Centers for Disease Control and Prevention in February last year, the number of patients with sudden cardiac arrest that occurred in 2020 is 61.6 per 100,000 population. By age, 6.7 people aged 10 to 19 years old and 493.6 people aged 80 years or older showed a tendency to increase with age.


Survival rate after sudden cardiac arrest was only 7.5%. However, it was confirmed that the survival rate increased by 2.4 times when the general public performed CPR. It was found that 4.8% of the survivors had recovered their brain function enough to be able to live a daily life alone.


However, related experts claim that the proportion of ordinary people who can perform CPR in Korea is still quite low compared to developed countries. Survival rates and return to daily life rates are also low.


In particular, interest in CPR education is growing in the wake of the Itaewon disaster that occurred in October of last year. The European Cardiopulmonary Resuscitation Association (ERC) also recently published an international journal 'Resuscitation' on the CPR that was led by the general public at the time of the Itaewon disaster, saying, "Most of the people who performed CPR or helped rescue experts were teenagers." The level was often not optimal,” he analyzed. With this in mind, some voices are growing that active expansion of CPR training and innovation in training methods are needed.


Tetrasignum focused on effective CPR training. It is to achieve innovation in medical education by developing a mixed reality (XR)-based medical education solution.


Tetra Signum CEO Jeon Sang-hoon said, “A medical professional at a tertiary hospital, a digital creative expert in the IT field, a development team with an average of 10 years or more of experience, and a global medical device sales and marketing expert gathered to develop XR-based medical education contents and services.” We want to improve various problems that the medical education market has not been able to solve for many years and realize the value of saving precious lives.”


I heard the details from CEO Jeon Sang-hoon.




◇From education to practice and evaluation∙∙∙Lectures provided according to guidelines


‘Tetra Signum’ is an XR-based medical education contents and service company established in October 2019. The goal is to reduce the global medical gap by solving unmet needs in the healthcare field with virtual reality (VR) technology.


Tetrasignum developed ‘MetaCPR’, a self-directed CPR training solution implemented in VR. In addition to CEO Jeon Sang-hoon, emergency medicine professor Cho Yoo-hwan at Seoul National University Bundang Hospital, Professor Tod Chang at Children's Hospital Los Angeles, USA, and Professor Ralph MacKinnony at Manchester Royal Infirmar in the UK. Medical and CPR specialists were in charge of training scenarios and verification.


MetaCPR consists of three parts: CPR training, practice by situation, and certification evaluation. First, the mannequin equipped with five special sensors is connected to the system through the Internet of Things (IoT), and can make mobile reservations, transmit data to the cloud, and check the results of training.


For training, AI instructors provide standardized lectures according to the country's CPR training guidelines. As it is implemented in VR, students can perform CPR directly on the mannequin in an environment similar to the real situation.


In particular, it can be performed according to various situations, from checking consciousness to requesting rescue, checking breathing, performing CPR, and even learning how to use an automatic external defibrillator (AED). They also provide feedback on practice. In a virtual environment, psychological training is conducted through communication between an AI instructor and a virtual human who needs help.


Lastly, trainees who have learned through education and practice by situation analyze and quantify data on CPR performed in real situations and receive certification evaluations. Trainees can learn more about their evaluation results and understand whether the CPR they performed was successful. If necessary, it is also possible to re-practice the missing part.


Above all, MetaCPR is a learning solution provided by AI instructors on a one-to-one (1:1) basis, rather than collective training conducted by most institutions. Individuals or a limited number of people are each trained in the metaverse environment.


Currently, Tetrasignum is providing a commercialization service for MetaCPR and plans to release a ‘MetaCPR MASS version’ soon. The MetaCPR MASS version consists of only a Head Mounted Display (HMD) and a mannequin without a kiosk. CEO Jeon explains that it is a product that is suitable for carrying around.


He said, “If MetaCPR is focused on 1:1 education, the MetaCPR MASS version receives CPR training for multiple trainees at the same time.” system,” he said.




◇“Need system improvement for CPR education”


CEO Jeon was proud that MetaCPR is the most advanced product in that not only effective CPR training but also psychological training is provided. It is also a great advantage to provide accurate feedback in real time.


“The speed and depth of chest compressions as well as how well they relax are very important indicators,” said CEO Jeon. “The training results of many people can be collected in the cloud and used as big data.” He added, “Through the accumulated accurate data, we will be able to present the basis for the establishment of education methods and policies.”


CEO Jeon said that based on MetaCPR, sales of Tetrasignum are gradually occurring from 2021. In addition, starting with the introduction of meta-CPR by tertiary general hospitals, inquiries about the introduction of meta-CPR have continued from large corporations and public institutions since last year.


However, CEO Jeon explained that since MetaCPR is a VR-based metaverse platform, it is often mistaken for a system that practices CPR in a virtual environment without actually performing CPR.


He said, “The trainee performs CPR on a mannequin, but through VR, you will feel the same as performing CPR on a real person.” You'll feel like you've saved a life."


Meanwhile, CEO Jeon emphasized the need to improve the system for CPR training. He pointed out that “with the development of technology, the world is undergoing a digital transformation very quickly,” but “CPR education has not changed over the past few decades.” At the same time, he emphasized, “There is a need for innovation related to CPR training.”


Tetrasignum plans to start the ‘International High School Student CPR Contest’ this year. The contest is a project in which students from major countries such as Korea, the United States, the United Kingdom, and Singapore communicate with each other and perform CPR on cloud lead borders. The goal is to provide voluntary motivation by performing CPR in a fun way like a game.


It is also collaborating with the College of Pharmacy at Seoul National University to advance animal practice education using VR. In addition, the development of cardiac and pulmonary rehabilitation programs will begin.


CEO Jeon said, “Even if CPR training is conducted in a virtual space, you will gain confidence in being able to perform CPR actively.” .
