摘要

The present invention relates to a method for correcting pulse wave transit time associated with diastolic blood pressure and systolic blood pressure, and the correction method can perform adaptive correction of the irregular change of pulse wave transit time caused by blood transfusion and intravenous transfusion, vasoactive drugs, surgical intervention, etc. in a clinical setting. A pulse wave transit time is determined by a time difference of an ear pulse wave and a toe pulse wave in the same cardiac cycle, and a few correction variables are extracted based on the pulse wave features, then a correction matrix is acquired to perform correction on the irregular change of pulse wave transit time. The corrected transit time can be used with available mathematical models for continuously measuring diastolic blood pressure and systolic blood pressure in each cardiac cycle in a clinical setting with high accuracy.
