- PublicaciónAcceso abiertoSistema interactivo de aprendizaje supervisado para la técnica de canulación en cirugía cardiovascular de adultos(Universidad de San Buenaventura, 2019) Vera Bonilla, Katherine; Chavarro Ceballos, María del Mar; Barco Santa, Andrés Felipe; Bacca Maya, Álvaro FelipeThis work presents the development of a supervised interactive learning system focused on the cannulation medical procedure. This surgical procedure, executed in most cardiovascular surgeries in adults, consists in introducing tubular devices into the hearts’ arteries to keep blood circulating during heart surgeries. These devices, called cannulas, are connected to an extracorporeal circulation unit that, among other things, injects a cardioplegia solution in order to temporarily stop the heart. The extracorporeal circulation unit then temporarily substitutes the heart tasks allowing the surgeons to operate. The importance of the procedure, and the lack of learning tools for it, have motivated this research.The proposed interactive system is aimed at medical doctor students and surgical instrumentation students with specialization in cardiovascular surgeries. The system implements three main modules to help the students to increasingly improve their knowledge on the cannulation procedure. First, an introductory module that tries to adapt the student to the system. Second, a module that includes a patient description and analysis, and selection of the appropriated instruments for the procedure. Finally, a surgery module in which students learn and practice the procedure of cannulation.The system integrates different multimedia technologies, such as mobile devices, augmented reality and databases, in order to provide an autonomous learning tool, no teacher intervention, whilst giving feedback to the students about his failures. Ergo, the student may execute the learning practice as many times as needed. Portability is promoted as the system runs on Android smartphones and uses only a poster to trigger the learning practice. At the same time, the system proposes a supervised practice for the teacher, i.e., visualization of student interactions either on run-time or see answers after completion of the practice. This is achieved by allowing the student answers to be stored in a web server that is latter accessed by the teacher in order to asses the student.In this thesis document are discussed the context of medical programs, the motivation and need for such a learning system, related work on the subject from which inspiration have been taken and the design, implementation and results of the research.
