Teaching Methods

The lectures will be mainly for discussing subjects with the students and problem-solving for theory application (with support from medical doctors). In the laboratory classes, students will develop computer applications for diagnostics and self-regulation, enhancing their self-learning and quest for knowledge skills.

Learning Outcomes

To know how to use the main quantitative algorithms used in the diagnosis of most common physiological systems (cardiovascular, respiratory, digestive, urinary tract, etc.).
Advanced treatment of physiological signals to extract their characteristics in temporal and frequency domains.
Theoretical analysis of homeostatic and self-regulation functions of human physiological systems. Design regulation systems for prostheses and clinical and hospital equipment.
