    The present research project implements an immersive virtual environment based on Virtual Reality for the simulation and recognition of an Intensive Care Unit, aimed at Nursing students from the Universidad Técnica de Ambato. The problem lies in the limited physical availability of specialized laboratories, which restricts students' prior technical familiarization with medical equipment. Methodologically, the research adopts a quantitative and qualitative approach, under an applied and field modality, collecting primary data at the Faculty of Health Sciences to coordinate the construction of a digital ecosystem through the Extreme Programming (XP) agile framework. The system comprises a web management platform in React, a server in NestJS with PostgreSQL, and a three-dimensional interactive simulator coded in Unity and C# for Meta Quest 3 standalone hardware. The results demonstrate a 100% level of graphical and morphological fidelity in the modeling of the 25 essential biomedical assets validated by expert judgment. Additionally, the usability evaluation using the standardized SUS scale applied to students reflects an outstanding acceptance index, where 9 out of 10 users confirm the ease of learning and consistency of the wireless environment. It is concluded that the interactive simulator eliminates motion sickness caused by image lag, reduces visual improvisation, and provides a functional educational tool that endows students with confidence for optimal placement in real clinical practice.

    Limitations in clinical laboratory infrastructure hinder practical training in surgical instrumentation for nursing students. In response, a virtual reality system was developed that simulates open surgical environments, allowing students to identify instruments and practice setting up the Mayo table in procedures such as cesarean sections and appendectomies. An immersive experience in simulated surgical environments was achieved through an application developed in Unity with C# and run on Meta Quest 3 glasses. The system was designed with an iterative and user-centered approach, applying the Extreme Programming (XP) methodology. To evaluate the complexity and efficiency of the development, a proprietary methodology was created that integrated metrics such as Cyclomatic Complexity, Halstead Complexity, real-time performance, and user experience evaluation through the NASA-TLX and SUS instruments. The validation of this methodology was carried out under the Design Science Research approach, which allowed the evaluation process to be scientifically structured. The results show that 93% of students rated the system as useful or very useful for identifying instruments, and 86.2% indicated that it facilitates practice outside the laboratory. In addition, the TAM questionnaire applied to eight experts yielded averages of 4.8 in perceived usefulness, 4.45 in ease of use, 4.67 in attitude toward use, and 4.75 in intention to adopt on a 5-point Likert scale. In future phases, it will incorporate a user management system with attendance control and progress resumption.
