CONCENTRATION-MEASUREMENT DEVICE AND CONCENTRATION-MEASUREMENT METHOD

A concentration measurement apparatus 1 measures a temporal relative change amount (cHb, O 2 Hb) of either or both of total hemoglobin concentration and oxygenated hemoglobin concentration in the head that vary due to repetition of chest compression, and includes a light incidence section 21 makin...

Beschreibung
Zusammenfassung:	A concentration measurement apparatus 1 measures a temporal relative change amount (cHb, O 2 Hb) of either or both of total hemoglobin concentration and oxygenated hemoglobin concentration in the head that vary due to repetition of chest compression, and includes a light incidence section 21 making measurement light incident on the head, a light detection section 22 detecting the measurement light propagated through the interior of the head and generating a detection signal in accordance with the intensity of the measurement light, and a CPU 14 determining, based on the detection signal, the relative change amount (cHb, O 2 Hb) and performing a filtering process of removing frequency components less than a predetermined frequency from frequency components contained in the relative change amount (cHb, O 2 Hb). A concentration measurement apparatus and a concentration measurement method that enable objective judgment of whether or not chest compression is being performed appropriately are thereby realized.
