Physical information monitor system having means for determining reference range for abnormality determination, based on moving average of previously obtained values

摘要

A physical information monitor system comprising: (a) physical information obtaining means for successively obtaining physical information values of a living subject; (b) moving average calculating means for continuously calculating a moving average of the physical information values successively obtained by the physical information obtaining means; (c) reference range determining means for determining a reference range on the basis of the moving average calculated by the moving average calculating means; and (d) abnormality determining means for determining whether one of the physical information values which is currently obtained by the physical information obtaining means is abnormal, the abnormality determining means generating an abnormality signal when the currently obtained physical information value is outside the reference range.
