RESUMO

The equipments use to monitoring physiological parameters isnt just crucial in patients who are submitted to some medical procedures but it is also of extreme value for animals in similar use. This project has as main objective the development of a monitor oxygen saturation and cardiac frequency for mice; the system is compound of a compact prototype device and optic sensor. In the present work, the Microchip microcontrollers technologies had been used, to realize many digitalization; the USB technology interface, to realize the communication with computers and the interface development developed with the available National Instruments software, the LabVIEW. In this study, the developed system was used in mice and have been realized many evaluations in laboratory and field for the prototype validation device. The cardiac beatings and oxygen saturation, as much in rest how in movement they had been detected by the prototype. The values of heart rate had varied of 545 to 700 while the values of oxygen saturation had varied of 80 to 95%.
