PROBLEM TO BE SOLVED: To increase a degree of oxygen saturation of a subject with high accuracy while reducing probability of sending air or oxygen with excessive pressure to the subject.SOLUTION: A control device includes: a calculation part for iteratively calculating a degree of oxygen saturation from a pulse wave signal of a subject and a control part for controlling a breathing support system to increase pressure of air or oxygen to be supplied to an airway of the subject till the degree of oxygen saturation calculated by the calculation part rises when the degree of oxygen saturation calculated by the calculation part decreases.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】過大な圧力の空気または酸素が被験者に送気される可能性を低減しながら、被験者の酸素飽和度を高い確度で上昇させる。【解決手段】被験者の脈波信号から酸素飽和度を反復して算定する算定部と、算定部が算定した酸素飽和度が低下した場合に、呼吸補助装置が被験者の気道に送気する空気または酸素の圧力を、算定部が算定した酸素飽和度が上昇するまで高くしていく制御部とを具備する制御装置。【選択図】図2
