PULSE PHOTOMETER AND METHOD FOR CALCULATING CONCENTRATION OF LIGHT ABSORBER IN BLOOD |
摘要 |
A pulse photometer includes: a first variation acquirer acquiring a first variation corresponding to a light attenuation variation of a first light beam due to pulsation of blood in a subject, based on a first intensity signal corresponding to an intensity of the first light beam that is transmitted through or reflected from a body of the subject, and that has a first wavelength; a second variation acquirer acquiring a second variation; and a concentration calculator calculating a blood light absorber concentration, based on the first and second variations, the second variation containing a first offset which is based on an inverse of the light attenuation variation of the first light beam. |
