To provide a venous pressure examination device capable of estimating quickly whether a central venous pressure is lower than a given standard or not.SOLUTION: An examination device estimates a central venous pressure by measuring a venous wave via a sensor at a prescribed measurement position on a subject. The estimation device includes an estimation unit that estimates that a central venous pressure of the subject is below a reference venous pressure, when no venous wave is detected by the sensor at a measurement position on the subject being in a specific posture such that a water column pressure corresponding to a vertical distance between a vertical peak point of a vein from the heart to the measurement position and the heart is at a predetermined reference venous pressure.SELECTED DRAWING: Figure 8 【課題】中心静脈圧が任意の基準より低いかどうかを速やかに推定可能な静脈圧検査装置を提供する。【解決手段】対象者の所定の測定位置においてセンサにより静脈波を測定することで中心静脈圧を推定する検査装置であって、心臓から測定位置までの静脈の垂直方向のピーク点と、心臓との垂直距離に対応する水柱圧が所定の基準静脈圧となる特定姿勢をした対象者の測定位置で、センサにより静脈波が検出されない場合、対象者の中心静脈圧が基準静脈圧未満と推定する推定部を有する。【選択図】図８
