Abstract
Traditional cardiopulmonary resuscitation training does not allow learners to accurately grasp power, depth and frequency. Therefore, this study aims to improve traditional training and reduce training volume, weight and price by using VR-CPRs learning support system. This study also provide immersive learning at a price lower than that currently prevalent in the market to impart the same level of learning and make CPR training more common. Our system makes it easier for individuals to learn cardiopulmonary resuscitation, making cardiopulmonary resuscitation training more common. Our system includes video health education, assisted real-time interactive operation tools, learning tests and other self-learning functions. Learners can practice on their own after watching the training film. The system reverberates the learner's power and frequency through a force-sensitive model to ensure that they are properly trained. Encourage users to learn CPR skills through immersive virtual reality settings that guide somatosensory interactions and support game-based learning. The study collected 100 college students who had never received CPR training. Before performing cardiopulmonary resuscitation on the force-sensitive model, participants were asked to complete a pre-test questionnaire to obtain pre-intervention learning outcomes. We introduced VR-CPR into CPR learning (intervention), assessed the outcome of the intervention, and asked participants to complete a post-test questionnaire. The study used VR-CPR to intensively study 85% of participants, indicating that the system is effective in promoting CPR learning, cultivating CPR learning interest, and improving public CPR ability.
Highlights
Brain cells can be damaged when the heart suddenly stops and die after 4–6 min of cerebral hypoxia
The 100 participants were first asked to complete the pretest questionnaire and perform Cardiopulmonary resuscitation (CPR) chest compression simulation on the force-sensitive model to assess their rate of successful CPR performance, which was treated as the preintervention learning outcome
The participants were asked to put on the virtual reality (VR)-CPRs device, a VR-based interactive learning support system, to perform CPR chest compression simulation to assess their rate of successful CPR performance, which was treated as the postintervention learning outcome
Summary
Brain cells can be damaged when the heart suddenly stops and die after 4–6 min of cerebral hypoxia. When cerebral hypoxia lasts for more than 10 min and no first aid is applied, brain damage becomes irreversible [1]. Cardiopulmonary resuscitation (CPR) is a crucial basic life-saving technique. CPR involves artificial respiration and chest compressions until the arrival of professional emergency personnel. Chest compressions enable blood to flow toward the brain, . Ensuring continuous oxygen supply to the brain and preventing brain damage. Hypoxia can be delayed and mortality can be reduced by 25% to 30% [2]. CPR performed by skilled personnel improves the survival rate of patients experiencing cardiac arrest [3], [4]
