[Health Plus] Jeon Sang-hoon, CEO of Tetrasignum "4 minutes of cardiac arrest golden time... CPR tra

Updated: Mar 20, 2023

On the 29th of last month, at the site of the Itaewon disaster, many citizens, along with paramedics, performed CPR (cardiopulmonary resuscitation) on the injured. However, as hundreds of casualties came out, the unfortunate situation became known as the citizens at the scene urgently sought someone who could perform CPR. It was an opportunity to highlight the importance of CPR education throughout our society.

Just as survival swimming education took root after the Sewol ferry disaster, after the Itaewon disaster, the education authorities plan to strengthen safety education for students in preparation for various situations, such as CPR and the use of an automatic external defibrillator (AED).

Jeon Sang-hoon, a professor of cardiothoracic surgery at Seoul National University Bundang Hospital, graduated from Kyungpook National University College of Medicine and worked at Kyungpook National University Hospital and Harvard Medical School Massachusetts Hospital in the United States.

As a cardiothoracic surgeon, he devoted himself to CPR education for a long time. In 2019, as a professor, he set up a healthcare startup called Tetrasignum. Subsequently, he introduced 'Meta CPR' training equipment using advanced technologies such as artificial intelligence (AI) and virtual reality (VR).

In an interview with Maeil Newspaper, Professor Jeon emphasized, “As the results of CPR training are systematized as big data through professional equipment, it will help establish effective CPR training directions in the future.”

CPR is an emergency procedure that maintains breathing and blood circulation when breathing or heartbeat stops until emergency responders arrive.

The 'golden time' that can save cardiac arrest patients is only 'four minutes'. If the blood supply to the brain is cut off for more than 4 minutes, permanent damage can be fatal. In other words, the key to CPR is to perform it as soon as the patient is found, before the ambulance arrives.

However, most of the CPR training conducted in schools or workplaces is limited to group training and video-based training.

Because of this, Korea's CPR implementation rate lags far behind other major countries. According to data from the Korea Centers for Disease Control and Prevention, Korea's '2020 public CPR performance rate' (the proportion of patients with sudden cardiac arrest who received CPR by the general public, excluding 'paramedics and medical personnel on duty' before arriving at the hospital) was 26.4% in the UK ( 70%), Japan (50.2%), and the United States (40.2%).

Tetrasignum's educational equipment 'Meta CPR' is characterized by the fact that you can enjoy the same training effect as if you actually did CPR through virtual reality (VR) goggles and a mannequin with built-in various sensors.

The mannequin has five built-in sensors that can detect ▷breathing volume ▷chest compression position ▷chest compression depth and speed ▷confirmation of consciousness and airway security. Based on these sensors, CPR results are scored for each item and stored as data in the cloud.

CPR can be performed in various environments such as classrooms and homes, and the gender of the virtual patient can be selected.

Professor Jeon said, "First of all, when you put on the goggles, an artificial intelligence (AI) instructor from Tetra Signum appears in virtual reality and explains the CPR process step by step according to the guidelines of the American Heart Association." When implemented, the AI instructor gives detailed guidance based on the data collected by the sensor, such as 'press a little deeper' or 'the speed seems too fast'."

In the final stage, you will perform CPR alone without an AI instructor. After that, a score is assigned, and this score is delivered to the administrator as well as to the person who performed CPR. What is lacking in CPR is embodied in data. The entire process takes 40 to 50 minutes to complete.

He said, "CPR doesn't have to be done on bare skin. If it's too thick, you'll have to take it off, but a T-shirt doesn't matter. It's okay to wear a bra," he said.

Creating a safe community through CPR training

Currently in Korea, 'MetaCPR' is being supplied to large corporations such as LG CNS and KT, as well as Asan Medical Center, Seoul National University Bundang Hospital, and Chungang Veterans Hospital. Abroad, it is being used for CPR training at Manchester University Hospital in the UK and Children's Hospital of Los Angeles at the University of Southern California in the US.

In Daegu-Gyeongbuk, Gimcheon Fire Station is using Tetrasignum's equipment for training.

Currently, some city and provincial offices of education are showing interest in CPR training for students.

Professor Jeon said, "'MetaCPR' includes a kiosk and is large. For this reason, other equipment that teachers can use to evaluate all students at school is coming soon, with only a mannequin and a head mount with sensors." When used in schools, cloud-managed data will also make it easier to assess the overall CPR training status of all students.”

He emphasized, "There will be differences in performance ability depending on the frequency of CPR training, such as 6 months or 1 year, and this data will help determine training intervals."

Lastly, he said that it is most important to spread a CPR education culture to create a safe community.

Professor Jeon said, “There is a case in which the survival rate of patients improved significantly when CPR training was conducted very diligently in King County, USA. said.
