Abstract: According to one embodiment of a method for measuring blood vessel elasticity, adapted to a sphygmus oscillation signal measured by pressure sensor of blood pressure equipment. This method for measuring blood vessel elasticity includes: uses the sphygmus oscillation signal to calculate systolic blood pressure and diastolic blood pressure; extracts a sphygmus signal after corresponds to the diastolic blood pressure; finds the maximum slope of the extracted sphygmus signal; finds a first time by using the maximum slope down to a reference pressure; then finds a second time by using the maximum slope down to the lowest point of the extracted sphygmus signal; and compares the first time and the second time to get the indicator of blood vessel elasticity.
