Abstract/OtherAbstract:
|
In this paper, a new noise reduction method was proposed for oscillometric blood pressure measurement. The proposed method uses a capacitive sensor and an adaptive filter to minimize blood pressure measurement error. Noise such as undesired external pressure applied to cuff was focused on. Three types of the distorted oscillation signals (no overlap, non-consecutive overlap, consecutive overlap between the noise and the oscillation) were used to compare the conventional method using linear interpolation and the proposed method using the adaptive filter. The proposed method outperformed the conventional method in the case of consecutive overlap between the noise and the oscillation. The proposed method could be useful for measuring blood pressure in such a noisy environment that the subject is being transported. |
