General Objetive

Create a virtual reality (VR) user interface to simulate a training scenario for ECMO (Extracorporeal Membrane Oxygenation System) therapy to enhance learning for cardiologists on the critical care team.

Specific Objetive

  1. Identify the conditions required to take the current practice of face-to-face training to virtual training, supported by a Virtual Reality interface.
  2. Design a Virtual Reality user interface to guide the cannulation training process for ECMO therapy.
  3. Evaluate the usability of the Virtual Reality user interface in terms of efficiency and effectiveness with a group of critical care experts from the FCV Cardiovascular Foundation.

methodology

The process of creating the virtual reality training was divided into three stages:
Methodology steps

Results

The validation aims to evaluate the proposed interface in terms of usability, including efficiency, effectiveness and satisfaction, as well as to assess the fidelity to the actual procedure and the learning objectives during this phase, which are to understand the cannulation procedure within ECMO therapy, to recognise possible risks during the procedure and to recognise the needs of a patient in respiratory failure.

The participants were divided into 3 groups:

INSIGHTS

→ Students and doctors have different behaviours when following the instructions on the interface. The first group being more receptive and patient, the second group trying to shorten times and finish the procedure quickly. It is suspected that this is due to the doctors' previous experience with intensive care patients.
‍
→ The learning objectives were met at a High to Very High level approximately, which confirms the overall objective of the project; the interface should function as a complementary training tool to the Cardiovascular Foundation Course (CVF).
‍
→ It is possible to say that the interface is effective, efficient and satisfactory for users, especially for health professionals who are in training for ECMO therapy.
‍
→ Participants demonstrated high levels of retention in all three groups assessed, considering that they all had different experiences with the procedure.
‍
→ It is possible to say that continued use of the interface could improve the acquisition of vital theoretical and practical concepts during the procedure.
