Abstract (en)
[origin: WO2009013287A1] The invention relates to a method for quasi-continuous determination of the blood pressure in a blood stream, wherein a time profile of a volume pulse of the blood in a blood stream is first measured. Thereafter, the first derivation is formed over the time of the measured volume pulse profile. From this derivation of the volume pulse profile, the profile of a transverse speed of change of the cross section of the blood stream is determined. By calibration of the transverse speed of change of the cross section of the blood stream on the basis of conventionally determined blood pressure values, it is possible subsequently to derive a quasi-continuous profile of the blood pressure value from the volume pulse.
