Biophysical phenomena in the circulatory system during indirect blood pressure measurement and analysis of measuring instruments

Conclusions

1. Conditions of local increase in the characteristic impedance of blood vessels leading to interference between incident and reflected waves of arterial pressure, analysis of which yields criteria for measurement of systolic and diastolic pressure, compared with the Korotov's sounds whose use is widely established in clinical practice, are examined.

2. The diameter of the occluded vessel at any moment of time of decompression can be determined sufficiently accurately by means of the method described.
