As we know from scientific research,process pulsation of blood in the peripheral vessels of the arms is formed by the interaction of the heart with the blood vessels the systemic circulation. This process represents the merger of the two pulse waves of pressure (3).
The first pulse pressure wave (1) is generated by the systolic blood volume, are transferred directly from the left ventricle of the heart to the fingers of the upper extremities.
The second pulse pressure wave (2) is generated by the reflection of blood volume from large main arteries of the lower extremities. This wave is sent back to the ascending aorta and then to the fingers of the upper extremities. The reflected pressure pulse wave propagates in arterial bed with a time delay relative to the direct pulse wave.
Fluctuations in the radial artery wall formed by the passage of direct and reflected pulse waves, taking into account the delay time.
Differential sphygmograph PULS-AS using pulse sensor detects the vibrations of the radial artery wall. Single sphygmogram differentiation provides a graph of the oscillation speed of the vessel wall. As a result of the double differentiation sphygmogram can get a graph of the acceleration fluctuations of the radial artery wall.
Differentiation sphygmogram simplifies the amplitude-time analysis of the schedule on the "specific" extrema points, which are formed as a result of single and double differentiation.
According to classical Chinese pulse diagnosis studies are conducted with various pressing force at the point of measurement (more). This method is implemented applanation sphygmography which is partially squeezed (applanation) surface overlying the radial artery at points Gun, Guan, Chi with simultaneous recording of the pulse wave. The compression of the radial artery by being pressed against the bone reduces the cross-vessel and causes a reaction of the body. Forms of direct and reflected pulse waves with different pressure-sensitive change. Change the ratio of amplitudes and time delays. Analysis of the recorded differential sphygmograms allows you to extract a significant amount of information about the state of various functional systems.
The computer technique of pulse diagnosis is based on the analysis of pulsogram by
mutual location of specific points and in comparison with a normalized pulsogram healthy person, showing one graph at beating pulse. This takes
into account the characteristic features of the amplitude and the time shift of these points and deviations from the normalized pulsogram.
The figure shows the real pulsogram
functional systems (Meridian), corresponding to normal or mutual dynamic balance "internal" and "external" on the theory of TCM.
On the normative pulsogram has maximum amplitude multidirectional peaks of S and R, positively directed peaks F, E and V, and two negatively directed peak U and X. the Peaks of S and R are similar in magnitude to the amplitude and time duration, as well as peaks F and E. The longest time is the curve V.
The peculiarity of the method, computer diagnostics is the algorithm of calculations, in which the measurement scale is accepted period of time corresponding to the distance between the points N and Z.
Depending on the functional status of the system (Meridian) there are various changes pulsogram compared with a normalized pulsogram. This can be to increase or decrease the amplitude of the peaks, increase or decrease the duration time of the peaks, changing the position of the vertex relative to each other, changing the shape of the peaks,
the connection(merger) of vertices, the appearance of additional peaks, the occurrence frequency of the oscillations on the main peaks.
Analysis of all changes pulsogram in each functional system (Meridian) in relation to each other, with the use of the software is the basis of computer pulse diagnosis.
The results of this analysis can be represented in the form of charts, graphs and tables reflecting the functional state of the organism as a whole. On the basis of such objective information you can confidently make diagnostic conclusions about the state of health of the person, to see violations of dynamic homeostasis and to find a way for the rehabilitation of health.
A distinctive feature of computerized pulse diagnosis is the possibility of application in the absence of marked clinical data, which is important for prevention research health. The results can be obtained in terms of TCM, and in terms of modern Western medicine .

At present time, holistic approach in diagnosis of the human body becomes more recognized in western medicine. Systematic analysis of all functional structures in their relationship and continuous dynamic change is required for complete understanding and assessment of the level of human health.
Today, the realization of the fact that dependence of medical care on a complex highly specialized diagnostic equipment leads to overspecialization of doctors and emergence of the tendency to treat certain organs rather than the whole organism is growing.
New methods and techniques, hardware and software systems, which combine together ideas of eastern medicine and achievements
of western technology began to appear in diagnostic practice. They are mainly designed for preventive diagnosis of human
health and determination of adaptive capacities of the organism. Various diagnostic systems based on methods of Voll,
Nakatani, "bio resonance" and NLS technologies had occurred. These methods are mainly based on the measurement of
electrical potentials on the human body, or perform attempts of measuring ultra-weak electromagnetic human radiation.
At the same time, taken parameters are transferred to the expert system, located in a computer program, which analyzes
results and makes diagnostic conclusions. The main disadvantages of these complex systems are low reliability and
objectivity of measuring these parameters. This is due to the fact that during the measurement process of electrical
potentials or ultra-weak electromagnetic human radiation in order to obtain reliable data it is required to create
ideal measurement conditions. This requires an area protected from electrical and electromagnetic interference.
Following external factors, which contribute a significant proportion of errors in measurements, can be noted:
* External electromagnetic radiation from mobile communication devices;
* Changes in natural electromagnetic background of the Earth;
* Climatic factors, such as relative humidity environment;
* Presence or absence of the grounding circuit and its value of electrical resistance;
* State of the skin of the patient and the thickness of the subcutaneous fat layer;
* Density and structure of the fabric of clothing, which patient is wearing (natural or synthetic);
*Wear and corrosion measuring probe and etc.
* It may be assumed that by activating human brain by electromagnetic radiation or sound or visual stimuli, you may, in a miraculous way,
receive feedback information from the brain as "encoded" electromagnetic radiation about the condition of all body organs, up to cellular
However, it is known that the main diagnostic method, which is adopted by Oriental medicine, is diagnosis
by pulse, measured in certain points of radial arteries of the patient, and which is always present in a living person.
