Popis:	Impedance plethysmography is a safe and noninvasive method for measuring peripheral hemodynamics. This paper’s aim is to develop a medical device system for a continuous monitoring of this parameter using the impedance technique. This system combines the advanced analog amplifier with the calculation power of digital signal processing to acquire real time monitoring. Our bioimpedance measuring system uses a generator which is under microprocessor control. The impedance signal processing, the user interface and the type of display were managed with Lab VIEW. This solution enables flexible output signal tuning with easily variable frequency and duty cycle. Experimental investigations are conducted in order to determine the optimum interrelation between current injector output characteristics, power supply and electrode spacing.
