Blood pressure measuring method using PPG signal is the one of many non-invasive blood pressure methods. In this study, we have studied a new method that estimates the blood pressure using wrist cuff and wrist PPG (photoplethysmograph) signal. During the deflation of the wrist cuff pressure, the PPG pulse appears at certain point that is similar to Korotkoff sound. After the pulse appeared, the morphology...
Oscillometric method is the method for the blood pressure measurement using mean arterial pressure (MAP). In the conventional method, the cuff pressure at the largest pulse is determined as MAP. However, it is difficult to find the largest oscillometric pulse from patients who have the cardiovascular disease or the elder subjects. Therefore, we studied a new method to determine the MAP by analyzing...
