摘要：
This concentration-measurement device (1) measures the relative change(s) over time (&Dgr； O2Hb and/or &Dgr； cHb) in oxygenated hemoglobin concentration and/or total hemoglobin concentration in the head due to repeated chest compressions. Said concentration-measurement device is provided with the following: a light-input unit (21) that inputs measurement light to the head； a light-detection unit (22) that detects measurement light that has propagated through the interior of the head and generates a detection signal corresponding to the intensity of said measurement light； and a CPU (14) that obtains the relative change(s) over time (&Dgr； O2Hb and/or &Dgr； cHb) on the basis of the detection signal and filters out frequency components of said relative change(s) over time (&Dgr； O2Hb and/or &Dgr； cHb) having frequencies lower than a prescribed frequency. This results in a concentration-measurement device and concentration-measurement method that can objectively determine whether or not chest compressions are being performed appropriately.
