[R wave relative oscillometric blood pressure measurement].
To improve the accuracy of oscillometric blood pressure measurement, an artifact rejection method for oscillations detection called R wave-relative method was developed. It was mainly based on the correlation between ECG R wave and oscillation. Combining with identification of oscillation characteristics this method can distinguish valid signals from interference. This algorithm has been implemented in 8098 microcontroller. Its program flowchart has also been presented in this paper.
