Embodiment Construction

[0033] exist figure 1 Plot the blood pressure P over time t in B , are shown in the figure in the static region ΔP sys and ΔP dia Systolic blood pressure change curve P from blood pressure value BW sys and diastolic blood pressure change curve P dia The transition time T T . Value ΔP sys and ΔP dia Its effect on blood pressure is caused by changes in physiological heartbeat volume and short-term vasodilation.

[0034] If systolic and diastolic blood pressure P sys and P dia And the patient's heart rate moves around the effective resting value, ie does not tend to a steady state value or leave a steady state value, then there is a cyclic resting period. The quiescent period of circulation is the premise of the validity of the internationally recognized arterial blood pressure boundary value (WHO, 1999 and JNC7, 2003). These limit values ​​are used as target parameters when regulating the arterial blood pressure.

[0035] The systolic and diastolic blood pressure val...

Abstract

The invention relates to a blood pressure measuring method, according to which a pulse oscillogram (PO) of a patient is defined, the blood pressure (pB) being then determined from said oscillogram and displayed. Reliable blood pressure values are obtained without additional cost to the user, by obtaining an evaluation criterion for the presence of haemodynamic stability from the individual pulse oscillogram, the determination of the blood pressure value or the determined blood pressure value being related to said criterion.

Description

technical field [0001] The invention relates to a blood pressure measurement method in which an oscillogram of a patient's pulse is determined and thus the blood pressure is determined and displayed, and also to a blood pressure measurement device for carrying out the method. Background technique [0002] One such blood pressure measurement method and blood pressure measurement device for non-invasive measurements is given in EP 1101 440 A1. In the known method and device of this automatic method based on oscillometric measurements, one or more pulse oscillograms are selectively generated during the blood pressure measurement in order to determine and display the blood pressure values ​​from these oscillograms. In the first operating mode, the systolic and diastolic blood pressure values ​​are determined in a measurement cycle in a conventional manner with a single pulse oscillogram, whereas in the second operating mode based on multiple inter- vals with 60-second intervals ...
