PROBLEM TO BE SOLVED: To provide an index of analgesia.SOLUTION: The analgesic index display device comprises: pulse wave volume observation means that observes pulse wave volume normalization pulse wave volume derivation means that derives normalization pulse wave volume that is obtained by dividing AC components of the pulse wave volume observed by the pulse wave volume observation means by DC components of the pulse wave volume other observation means that observes at least one biological index different from the pulse wave volume noxious stimulus analgesic balance derivation means that derives an index of a noxious stimulus analgesic balance from the normalization pulse wave volume and the biological index and display means that displays an index of the noxious stimulus analgesic balance.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】鎮痛の指標を提供する。【解決手段】脈波容積を観測する脈波容積観測手段と、前記脈波容積観測手段によって観測された脈波容積の交流成分を該脈波容積の直流成分で除算した規準化脈波容積を導出する規準化脈波容積導出手段と、前記脈波容積とは異なる一以上の生体指標を観測するその他観測手段と、前記規準化脈波容積と前記生体指標から侵害刺激鎮痛バランスの指標を導出する侵害刺激鎮痛バランス導出手段と、前記侵害刺激鎮痛バランスの指標を表示する表示手段とを備えたことを特徴とする鎮痛指標表示装置。【選択図】図2
