The Study Of Acquisition And Processing System Of Multiple Physiological Parameters Based On LabVIEW

The electrocardiogram (ECG) ,blood pressure (BP) ,pulse and blood oxygen saturation ( SO₂) are the most fundamental bio-indicators of human beings. It's helpful for doctors to measure these biology signals in the first-aid outside the hospital. The system is designed and realized for the deficiencies that the existing monitoring system which can only get a small number of simple physiological parameters for analysis, and lacks of the ability of analysis some more complex physical parameters. The system not only completed real-time display of the general ECG, respiration and pulse wave , and the measurement of pulse, heart rate, oxygen saturation, blood pressure and other parameters, but also through the analysis of algorithms, estimates HRV, cardiovascular parameters such as: SV (out of stroke) , TPR (peripheral resistance) and ABI (ankle brachial factors) , and other physiological parameters. Finally use of modern technology to achieve long-distance monitoring and control network.The system whose system software used LabVIEW graphical programming environment, is an acquisition and processing system based on computer technology. It can complete long-distance communications through network with the functions that displaying, playback and printing. The function of the system definition can be flexible, easy to meet user requirements, and the system has a good human-computer interface, easy to operate.
