A measurement device pressurizes two cuffs in a state in which the cuffs are attached to the distal side and the proximal side of the measurement device, respectively, calculates an AI value or the like based on a pulse wave detected from a change in cuff pressure on the distal side while pressurizing the two cuffs, and determines that avascularization on the distal side has been completed if the AI value or the like has converged. Once it is determined that avascularization has been completed, the cuff pressure on the distal side is fixed, and a pulse wave is detected from a change in cuff pressure on the proximal side in a state in which the distal side is avascularized.
