Abstract: In an electronic blood pressure meter, artifacts or disturbances of blood pressure measurement due to the motions of the arm or the body of the person whose blood pressure is to be measured is detected from the level of a pulse wave signal. If the pulse wave signal continues to be above a certain reference level for more than a certain threshold time period, it is determined to be indicative of the presence of an artifact which prevents accurate measurement of blood pressure. This process of detecting an artifact can be conveniently implemented as an interruption routine of a microprocessor. When such an artifact is detected, a warning signal may be issued and the cuff may be rapidly vented so that the renewed measurement can be carried out without any further ado.
