Objective:A new method of measuring pulse wave velocity

double-cuff method

has been proposed based on oscillometric method and used to practice to validate its reliability in this paper.Methods:In this method

two cuffs are used to collect pulse wave signals of humerus and oar artery respectively.We analyse the two signals’time difference Δt by choosing wave boot as the pulse beating’ start point.Pulse wave velocity can be calculated according to the formula PWV=ΔS/Δt

in which ΔS is the distance between humerus and oar artery and can be measured by a soft ruler.Results:The double cuff method

which has the advantages of simple operation

speedy measurement and low cost

can measure pulse wave velocity reliably

accurately

fast and simply.Conclusions:The pulse wave velocity measured by this new method

which can reflect the differences between normal people and critical or already hypertension suffers

is significant in forecasting hypertension.
