Abstract: This blood pressure/pulse wave measurement device obtains a pulse wave velocity (baPWV) that is an index representing the arterial stiffness of a subject. A lower limb/upper limb blood pressure ratio (ABI) that is an index representing the clogging of the blood vessels of a subject is obtained. When the lower limb/upper limb blood pressure ratio (ABI) of the subject surpasses a preset first threshold value, a point (Px) representing the pulse wave velocity (baPWV) is displayed on a one-dimensional graph (46). When the lower limb/upper limb blood pressure ratio (ABI) of the subject is equal to or less than the preset first threshold value, a point representing the lower limb/upper limb blood pressure ratio (ABI) is displayed on the one-dimensional graph (46) instead of the point representing the pulse wave velocity (baPWV).

Abstract: A blood pressure/pulse wave measurement device is provided with: first and second cuffs for pressing parts of the upper and lower limbs of a subject; and first and second tubing connected to the individual first and second cuffs. The blood pressure/pulse wave measurement device is additionally provided with: a first detection unit that is connected to the first cuffs via the first tubing and that detects a first pulse wave propagated through the first tubing; a second detection unit that is connected to the second cuffs via the second tubing and that detects a second pulse wave propagated through the second tubing; and a control unit that calculates the ankle brachial index and pulse wave velocity using the first and second pulse waves. The first detection unit and the control unit are accommodated within a first housing. The second detection unit is accommodated within a second housing.
