Impedance plethysmograph

bodywith phlebographywith rheography

The computer-based reograph for non-invasive studies of central hemodynamics, blood flow in the brain, limbs, and internal organs. The mobile version includes a special case that contains the laptop, reograph and all accessories. Simultaneous registration of up to 4 rheogram channels and ECG by one lead. Implementation of techniques: a)rheoencephalography (REG); b)rheovasography (RVG); c)rheohepatography (RHG); d)rheopulmonography (RPG); e)rheorenography (RRG); f)transthoracic tetrapolar rheocardiography by Kubichek; g)integral rheocardiography by Tishchenko. Registration of base impedance, volume and differential reogram. Ability to carry out a variety of functional tests with their subsequent comparison. Calculation of the current value of heart rate, constructing a rhythmogram. Automatic analysis of rheogram: classification of types of rheocomplexes. Automatic placement of labels with the ability of their correction by the user. Choosing a probing frequency and a constant time for each technique. Analysis of heart rate variability (HRV) Automatic description of the rheographic curve Number of rheographic channels:4 Number of electrocardiographic channels:1 Range of measuring the basic impedance:10..500 Ohm Range of measuring the dynamic impedance component:0,01...0,5 Ohm Range of time interval measurements:0,1 … 5,0 sec Intrinsic noise level referred to the input:0.003 Ohm max Probing current frequency values:14, 28, 56, 112 kHz ± 20 % Connection to the PC:Via USB interface Electric safety parameters: Class II of BF type as per EN 60601-1:2015 without defibrillator discharge protection
