Patent ID: 8864678

Claim:
A blood pressure measuring method, comprising: determining a blood pressure value of a patient during a single blood pressure measurement cycle; measuring a pulse sequence of the patient during the single blood pressure measurement cycle; automatically determining with an evaluating device whether the blood pressure value was measured at a circulatory rest of the patient during the single blood pressure measurement cycle, by at least one of: a) ascertaining a pulse period progression ( 2 . 2 ) of the pulse sequence, comparing pulse period durations of at least one initial range and one terminal range of the pulse period progression and using any deviation in the pulse period durations of the initial range (T initial ) and of the terminal range (T terminal ) as an assessment criterion for determining the circulatory rest, or the entire progression of all the pulse periods of the pulse sequence is ascertained with regard to a change over time, and the change is used as a measure of the circulatory rest; or b) ascertaining a pulse amplitude progression ( 3 ) of the pulse sequence, and from the pulse amplitude progression determining a gradient (a) in an ascending range thereof, a gradient (β) in a descending range thereof, a plateau width (PL) about a maximum thereof, or a combination thereof; or c) ascertaining a pulse curve of the pulse sequence, analyzing a shape of the pulse curve ( 6 ) to determine one or more gradients at at least one point in an ascending or descending pulse edge, and examining a change in the pulse curve over time in the one or more gradients, or a ratio of the gradients at at least two points for various pulses; and the evaluating device determining and indicating whether the blood pressure value was obtained during the circulatory rest, or whether a corrected blood pressure value is to be determined; wherein the evaluating device automatically performs at least two of: step a), step b), or step c), to determine the circulatory rest, and further comprising applying a different weighting to each of the at least two of the steps a), b), or c) in determining the circulatory rest.
