Abstract
A testing apparatus for estimating a central venous pressure by measuring a venous pulse by a sensor at a predetermined measurement position of a target person is equipped with an estimation unit which estimates that the central venous pressure of the target person is lower than a reference venous pressure if the venous pulse is not detected by the sensor at the predetermined measurement position of the target person who assumes a particular posture with which a water-gauge pressure corresponding to a vertical distance between the heart of the target person and a peak point, in the vertical direction, of a vein leading from the heart to the measurement position coincides with the reference venous pressure.
