Equipamentos Biomédicos

Electrotechnics;
Electronics.

The course unit will be taught through lectures and laboratory classes (presential classroom lessons).

Laboratory classes will take place in a laboratory with computers, power supplies, signal generators, oscilloscopes, and other electronic components in order to carry out practical assignments and projects, after exposing the theoretical subjects.

Course Aims

• To know and understand the principles and technologies used in the most common hospital biomedical equipment;
• To know and understand the classification of biomedical equipment and its implications;
• Diagnose technical problems observed in biomedical equipment;
