Venous pressure testing apparatus, non-transitory computer readable storage medium, and venous pressure testing method

A venous pressure testing apparatus for estimating a central venous pressure of a target person by measuring a venous pulse by a sensor at a predetermined measurement position of the target person, comprising:

• at least one processor configured to estimate that the central venous pressure of the target person is lower than a received predetermined reference venous pressure if the venous pulse is not detected by the sensor at the predetermined measurement position of the target person,
• wherein the target person has a particular posture,
• wherein the reference venous pressure coincides with a hydrostatic pressure corresponding to an elevation difference between the heart of the target person and a peak elevation of a vein,
• wherein the vein leads from the heart to the measurement position
• wherein the at least one processor estimates that the central venous pressure of the target person is higher than or equal to the reference venous pressure if the venous pulse is detected by the sensor at the measurement position of the target person who assumes the particular posture,
• wherein the particular posture of the target person is specified based on the received reference venous pressure,
• wherein the particular posture is an angle formed by an upper part and a lower part of a body of the target person whose arms hang down, and
• wherein the at least one processor is configured to cause the target person to assume the particular posture by setting a bend angle of a back contact surface, the back contact surface being in contact with the back of the target person, of a posture guide tool capable of adjusting the angle formed by the upper part and the lower part of the body of the target person by bending the back contact surface, at the angle formed by the upper part and the lower part of the body of the target person that has been specified as the particular posture by the specification unit.
