Simple telemetry system for medical and industry data transmission

The presented contribution describes a hardware and software for wireless stress test system and data evaluation. The exercise testing remains pre-eminent as a non-invasive technique for the diagnosis of coronary artery disease. Heart rate frequency, breathing frequency, tidal volume, pulmonary ventilation, oxygen consumption, carbon dioxide output and so called ventilatory equivalent and respiratory quotient are measured and computed. Applications are: rehabilitation, work medicine, sport medicine, nutrition, pneumology, cardiology and any application that needs to study cardiopulmonary system. Data transmission using frequency modulation with 138 channels digitally adjustable is used
