Document Type and Number:
Japanese Patent JP6628720
Kind Code:
B2
Abstract:
A circulation time measurement device includes: a signal acquisition unit that acquires an air flow signal indicating a temporal change of an air flow of breathing and an oxygen saturation signal indicating a temporal change of oxygen saturation; and a circulation time calculation unit that measures an oxygen delivery circulation time of blood based on a time difference between a predetermined first time in the air flow signal and a second time in the oxygen saturation signal indicating an increase in oxygen saturation corresponding to resumption of breathing at the first time.
