  Comparison of tacho-oscillographic and oscillometric methods for human blood
pressure measurement with cuff occlusion in the same device at the same time is
described. For this purpose the measurement system and software for signal
processing that realize these methods in the same device was developed.
Experiment shows that oscillometric method with photoplethysmographic (PPG)
sensors does not require empiric criteria to search systolic and diastolic
blood pressure parameters due to possibility to apply correlation analysis.
Perspectives of applying oscillometric method with PPG sensors in automatic
blood pressure monitors is showed.
