Real time monitoring of electrocardiography and blood volume using rtai on linux

In this study, Real Time reading and monitoring of Electrocardiography (ECG) and Blood Pressure (BP) have been implemented with the Real Time Application Interface (RTAI) on Linux operating system. The Real Time Application Interface supported by linux is used to provide real time concept. The installation and running of RTAI are also explained. The ECG and BP signals have been applied to instrumentation amplifiers and filters to clear and to amplify the signal. This clear signal is acquired by an Advantech data acquisition card which has 12 bit resolution at 1000 Hz. Software has been developed for analyzing signals. The changes of systolic and diastolic pressure and the R points interval of ECG have been observed. The baroreceptor sensitivity (BRS) has been calculated. The RTAI functions and C programming language have been used in the software. Keywords: Linux, Real Time Application Interface, Electrocardiogram, Blood Pressure, Data Acquisition
