Abstract:
1. Apparatus An apparatus for measuring hemodynamic parameters, by non-invasive, cuff based occlusive, blood pressure measurement, which apparatus comprises occlusive, oscillometric automatic blood pressure meter and units, determining the values of hemodynamic parameters, comprising an oscillation wave separating and storing signal detector for detecting an oscillation signal, the sampling rate thereof is at least 200/heart cycle; and said signal detector has a storage unit resolution that is organized at least 9 bit, a digital anti-filter connected to the signal detector to compensate the distortions rising at sampling, separating and digitizing the oscillation wave, detected by the signal detector, an amplitude arithmetic unit connected to the anti-filter establishing an Augmentation Index (Aix); and a synthesizing unit connected to the anti-filter establishing an Ejection Duration (ED).
