Cardiac Arrest

CPR and AED (Defibrillator) in Augmented Reality

Cardiac arrest is when the heart stops beating regularly and can no longer pump blood through the body. There are a variety of causes – heart attack, drowning, stroke, electrocution, suffocation or other trauma. With over 500,000 cardiac arrests occurring each year, CPR training can mean the difference between life and death.

CPR (Cardiopulmonary resuscitation) is a first aid procedure that involves chest compressions that help to preserve oxygenated blood flow to the brain and other vital organs, until normal cardiac rhythm can be restored. Every second counts when the heart is no longer beating: chance of survival decreases by 10% every minute without assistance. If you know how to handle cardiac arrest, the victim's chances of survival and recovery can improve up to 30%.

The American Heart Association reports that 70% of people feel helpless in the event of a cardiac emergency because they either do not know how to effectively administer CPR or their CPR certification has lapsed. This AR simulator is the ideal tool for learning CPR for the first time, or as a refresher after initial medical training.

Learning Objectives

The simulator helps students understand the key steps in carrying out adult CPR. How and when to start CPR, how to perform it to successful completion and how to use an AED (Automatic External Defibrillator).

Audience

This simulator can be used as an in person, hands on training tool for workplaces and healthcare providers and works with any audience. It also provides feedback on user performance, helping them to perform CPR and improve their lifesaving skills.

Training Scenarios

All the CPR training scenarios are represented in photorealistic 3D visuals in Augmented Reality that allows the trainees to practice first aid rescue in a safe and immersive environment. The rendering is extremely realistic and is based on input from healthcare professionals.

Students are able to move around freely in the scene to gather all the information necessary to make the right decision. Trainees use their phone's camera to explore a realistic life-size emergency scenario, in which a man has just fallen in front of them as a result of a heart attack. They are asked to effectively complete CPR and/or an AED procedure to save the victim's life.

Scenario 1: CPR procedure without an AED

The feeling of compressing a chest can't be replicated in AR. However, the many steps to complete, the choices to make, the hand placement on the body, and the tempo at which you execute a CPR may all be reproduced with a high level of realism. Trainees experience the emotional stress of carrying out a basic life support procedure while they perform CPR in AR, on a photorealistic human body.

Scenario 2: CPR procedure with an AED

Technically AED is not the most difficult first aid procedure. However, under stressful conditions, it's easy to forget what you have learned during a CPR class. This scenario helps trainees remember the sequence of steps to carry out, and to be as quick and efficient as possible if they find themselves in an emergency situation. The objective is also to familiarize them with the use of an AED to make the object less intimidating.

Scenario 3: CPR in Action | A 3D look inside the body

This simulation demonstrates, from inside the body, the crucial importance of performing CPR as shown in the two previous scenarios. It allows the user to observe the effects of properly executed chest compressions on the victim's circulatory and respiratory systems. They will also visually comprehend the consequences of improperly performed gestures.
