Abstract

The invention provides an automatic real-time calibration method for continuous blood pressure measurement. The method comprises the following steps of: determining a PPG value PD0 of an artery in a de-loading state; adjusting the PD0 according to a first preset amplitude range, and recording the adjusted PD0 as PDadj; taking the PDadj as an input parameter of an automatic control algorithm, and enabling the PDadj to fluctuate up and down near the PD0 according to a second preset amplitude range; determining a difference value delta PD between each PDadj and a PPG signal; in the fluctuation range of the PDadj, when the maximum value of the delta PD appears, determining the PDadj corresponding to the maximum delta PD in real time; and updating the PD0 according to the PDadj corresponding to the maximum delta PD. With the method adopted, the problem that a blood pressure measurement result is inaccurate due to the drifting of the de-loading state of the artery during the continuous blood pressure measured based on a volume compensation method for decades is solved. Even if the blood pressure is measured for a long time, a blood pressure value is kept stable.

Description

Technical field [0001] The present invention relates to the field of blood pressure measurement, in particular, an automatic real-time calibration method for continuous blood pressure measurements. Background technique [0002] 1973 Polish scientist Penaz proposed a blood vessel capacity compensation method to measure continuous blood pressure. The basic principle is to apply an external force opposite to the blood pressure pressure of the artery, such as an external force in the arterial blood pressure pressure, then internal and external pressure in the arterial vessels cancel each other, the blood vessel wall itself is zero, and is in the most relaxed state, called " Load state. [0003] From the above principles, it is possible to determine the "depletion state" of the artery, find the corresponding vascular diameter D0, and the external force is controlled to lock the blood vessel diameter in D0, then this external force is equal to the real-time blood pressure. Therefore, i...
