| Popis: | Cuff pulse waves together with cuff pressure are essential in modern automatic blood pressure (BP) devices. Most methods for BP determination employ cuff wave amplitudes. Physiological features of cuff waves have been neglected. In this study we described the origin of amplitude based approach to automatic BP determination. The cuff waves are commonly called oscillations and the methods for BP determination are called oscillometric methods. Excessive filtering of cuff waves causes obliteration of important physiological features of the waves. We introduced wider frequency band filtering that opens avenues to more sophisticated processing of cuff waves. Examples of cuff pulse wave applications beyond BP determination are shown. |
