A new method of photoplethysmogram analysis for complex assessment of natural fluctuations of pulse blood filling and tone of peripheral arteries based on the results of long-term photoplethysmographic monitoring of peripheral volumetric pulse is proposed. The method is based on finding the variational, statistical and spectral indicators of the relative amplitude characteristics of the photoplethysmogram. Standard algorithms of variational, statistical and spectral analysis are used to realize the method. The method can be used for the analysis of disorders of regulation of regional vascular pulse blood filling, tone arteries of small diameter, as well as conditions of regional venous return of blood to the heart. |
