Abstract
This work discusses the design of a new method for the continuous differential record of the variable Arterial Blood Pressure (PSA) for noninvasive method (oscillometric) to be employed during the study of the vasovagal syncope in subjects with problems of peripheral circulation during the tilt test. We analyze the different sections of the proposed system, it includes the selection and characterization of the pressure transducer for the differential measurement of the variable; as well as the blocks of the analog channel (multiplexer, amplifier, and filters) and the ARDUINO ONE platform to achieve the control of the acquisition of the data; the control of the filling and emptying of cuffs and besides the communication with a station of processing and control through an interface developed in C #. The obtained results evidence adequate linearity and frequency response, allowing to the study of the variable PSA during the development of Tilt test.
