METHOD AND SYSTEM FOR CUFF PRESSURE REVERSIONS

摘要

A method and system for determining when to make a reversion to smaller cuff pressure steps during an oscillometric blood pressure measurement is disclosed. The method and system comprise comparing conformance of oscillometric envelope blood pressure data with previous blood pressure data, including measuring a shift between the oscillometric envelope blood pressure data and an oscillometric envelope derived from the previous blood pressure data. In addition, the method and system include making a reversion decision based on whether the shift exceeds an allowable threshold. Once a reversion decision is made a subsequent decision may be made as to the need for increasing the cuff pressure level.
