自律神経系用脈拍数モニタの開発

抄録

There are many studies on the autonomic nervous system, which analyze the function of the autonomic nervous system by measuring pulse rate. However, many of these studies do not include the pulse rate data during under the stress, because it is so difficult to measure the fast change of pulse rate during stress and during body movement caused by the stress. The purpose of this study is to develop the monitor, which can predict the dental emergency. It monitors fast pulse rate change during body movement aroused by stress. Under this condition, we have developed the new algorithms, which can measure instantaneous pulse rate under body movement. On the other hand we have developed the new simulator which generate signals for pulse oxy-meter from the analog wave forms taken from patient. It makes us possible to compare the specification of any kind of pulse oxy-meters. This paper includes the evaluation of the new algorithm from the clinical points and the comparison between our algorithm and the other algorithms on the point of performance for pulse rate counting.
