A new blood pressure measurement using dual-cuffs

Most automatic sphygmomanometers use oscillometric method with a blood pressure cuff. Conventional oscillometric sphygmomanometer is simple to use and it needs no peripheral device. However, the method provides no guarantee of accuracy in all circumstance, because it is based on statistics. In this paper, we propose a new oscillometric method with two cuffs. A cuff is placed on upper arm as usual and another cuff is added on forearm. By adding one more blood pressure cuff, there are two different waveforms are shown and the different characteristics between both cuffs can be compared. The results of our experiments show that it is possible to measure blood pressure using dual-cuff oscillometric method.
