Abstract
A blood pressure monitoring apparatus includes a blood pressure measuring device for measuring blood pressure employing a cuff, a pulse wave propagation time measuring device for measuring the pulse wave propagation time, a hemodynamics measuring device for measuring the hemodynamics, and a control device for controlling the blood pressure measuring device on the basis of a change in pulse wave propagation time measured by the pulse wave propagation time measuring device and a change in hemodynamics measured by the hemodynamics measuring device. The control device controls the blood pressure measuring device to measure the blood pressure on the basis of the amount of change and change trend in the pulse wave propagation time measured by the pulse wave propagation time measuring device, and the amount of change and change trend in the hemodynamics measured by the hemodynamics measuring device.
