Learn CPR alone with 'AI VR'

Updated: Mar 20, 2023

The number of patients with sudden cardiac arrest in Korea increased by about 40% from 10 years ago to 30,539 in 2018. In the meantime, the number of participants in cardiopulmonary resuscitation (CPR) training has more than doubled from 277,598 cases in 2013 to 694,786 cases in 2015. However, an analysis of 2500 cases of CPR performed between 2016 and 2017 showed that only 6% of resuscitation was accurate (2020, Professor's team, Department of Emergency Medicine, Dongtan Sacred Heart Hospital, Hallym University). This means that CPR training needs to be reexamined.

As the loss of life and society due to cardiac arrest soars, about 3 million people, including fire departments, soldiers, school teachers, and doctors, are required to learn CPR. Although there are about 3 million people subject to legal obligations, the number of victims due to cardiac arrest is still not decreasing. In the meantime, CPR has been taught by 4-5 people sitting around with a dummy as a group education center. It is true that although they are making progress in their own way, they are not getting perfect education in various situations. CPR can save 97% of cardiac arrest patients within 1 minute, 75% within 3 minutes, and about 50% within 4 minutes. The golden time for cardiac arrest is about 4 minutes.

In the midst of this, 'TetraSignum (CEO Song Young-il), a venture company specializing in healthcare contents, announced that it had developed and marketed 'CBS v2.0 Standard,' a self-directed learning artificial intelligence VR CPR training solution. It is a package that can be installed and managed simply and easily without a complicated installation manual and consists of a touch display, PC, mannequin, VR device (HMD, base station, tracker), foldable mat, mouse shield, VR mask, etc.

Anyone over the age of 12 can learn CPR perfectly by wearing a HMD (stereoscopic 3D helmet) at any time and following the instructions of a professional artificial intelligence instructor named Aiden. A CPR expert instructor appears in virtual reality and teaches the learners by making eye contact with them. The required time is 30 minutes for standard learning, 10 minutes for practice by situation, and 10 minutes for certification evaluation. The standard learning is a curriculum that allows the general public to learn CPR and how to use an automatic external defibrillator in detail. Practice by situation is a process of practicing each of two situations with different backgrounds and first aid procedures, and certification evaluation is a process of evaluating all stages of CPR and how to use an automatic external defibrillator. Practical practice similar to an emergency situation creates a sense of realism so that CPR can be performed with confidence in an actual emergency situation. CBS v2.0 Standard can train 2,000 people per year.

Jeon Sang-hoon, founder of Tetrasignum (Professor of Thoracic Surgery at Seoul National University Bundang Hospital and former director of the hospital), said, "The place where cardiac arrest occurs is 63% at home, 20% in public places, and 17% in other places. He emphasized that CPR can save the lives of family members and people around them by learning it through VR from time to time without receiving group training once in a while." In fact, companies that need to receive CPR training, such as hospitals, colleges of education, airlines, and KTX, find it difficult to gather employees for CPR training at once, and it is difficult to take out workers for several hours and proceed with the training calmly. In addition, as a small number of instructors conduct group training, the concentration is relatively low and only the instructors provide subjective feedback.

The artificial intelligence VR CPR training solution is characterized by using precision sensors to provide real-time feedback through one-on-one training with an artificial intelligence instructor to help self-correct. It is designed so that you can learn more thoroughly and closely than receiving education in an offline space. For example, a vibration sensor is installed on the shoulder to check if the patient's shoulder is tapped hard enough. In addition, a chest compression sensor that measures the depth and speed of chest compression and a magnetic proximity sensor that measures the position of chest compression are located on the chest, and a rotary encoder sensor that precisely measures the tilt angle of the head to induce airway security training is located on the right ear. , The air pressure sensor is installed on the face, which displays the respiratory volume in quantitative numbers in real time and induces the provision of accurate respiratory volume. In addition, it provides accurate and detailed measurement indicators for each stage of CPR and manages big data in the CBS data center.

On the other hand, looking at the major status of CPR education by country, in the United States, laws on CPR and AED education are enacted in schools in 36 states, the Ministry of Labor regulates CPR education, AED installation, management and distribution, and public schools provide CPR education subsidies by federal law. Japan has made CPR training compulsory for elementary, middle and high school guidance and driver's license acquisition, Germany has made CPR training compulsory for driver's license acquisition and schools, and the UK has decided to implement CPR training in all high schools from September 2020.
