Title in Portuguese
Desenvolvimento de sistemas bio-telemétricos para a medida da freqüencia cardíaca e do ritmo respiratório.
Keywords in Portuguese
Bio-telemetria
Freqüencia cardíaca
Ritmo respiratório
Ultrassom
Abstract in Portuguese
O desenvolvimento da Física tem possibilitado sua atuação em vários campos, e mais recentemente, na Medicina, onde estudos da Freqüência Cardíaca e do Ritmo Respiratório fornecem informações importantes acerca de processos fisiológicos e podem ser um útil instrumento diagnóstico e terapêutico. Nestes estudos, em muitos casos, necessita-se que as variáveis sejam monitoradas telemétricamente, como a observação de atletas e pacientes pré e pós-enfartados durante a prática desportiva, e estudos de animais em seu habitat natural. Desenvolvemos, portanto, um protótipo capaz de medí-las por métodos não invasivos (métodos que dispensam urna exposição cirúrgica), baseando-se na aplicação do Efeito Doppler Ultrasônico e no Movimento Mecânico do Tórax. Este protótipo consta de um conjunto de transmissores e receptores que captam e Freqüência Cardíaca e o Ritmo Respiratório, registrando de forma audível, gráfica e numérica, conforme tempos pré-estabelecidos.

Abstract in English
The development of physics made action in various fields possible, and more recently, in Medicine, studies of heart frequency and breathing rhythm give important information about physiological status and are useful for diagnostics and therapeutics. In these studies, in many cases, it is necessary that variables could be monitored by telemetry, as p.e. observation of athletes and also before and post-glutted patients during sport practices, and studies of animals in their own habitat. We are developing, therefore, a telemetric prototype which is capable of measuring them by non-invasive methods (methods that exempt a surgical exposure), based upon application of the Ultrasonic Doppler effect and of the Mechanical Movement of thorax. This prototype consist of a group of transmitters and receivers which are getting heart beat frequency and breathing rhythm recorded by such forms: audible, graphic and numerical, in before established periods.
