Abstract
A blood pressure acquisition apparatus (26) that acquires a blood pressure of a test subject on the basis of an output of a tonometry-type pulse wave meter (21) is provided with a control unit (26). The pulse wave meter has a compressing part (211a) that compresses the test subject. The control unit executes: arrangement determination processing (S2) for determining whether or not the compressing part of the pulse wave meter is arranged at an appropriate position with respect to the test subject; and blood pressure acquisition processing (S4) for acquiring a first systolic blood pressure of the test subject on the basis of a pulse wave of the test subject, wherein the pulse wave has been acquired by the pulse wave meter in a state where the compressing part is arranged at the appropriate position.
