Abstract
An oxygen saturation measuring apparatus capable of measuring arterial blood oxidation saturation (SpO2), and tissue oxygen saturation (rSO2), safely, easily and economically at a desired position of a biological body for a long time continuously. A ROM stores the distance information between a light emitting unit and a light receiving unit situated corresponding to the depth of a target intended to be measured for tissue oxygen saturation, a light emission driving unit makes the light emitting unit emit light in an amount of light corresponding to the distance information, MPU makes the light emitting unit emit a pulses capable of measuring the tissue oxygen saturation, MPU applies pulse capable of measuring the tissue oxygen saturation from the light emission driving unit to the light emitting unit, and the pulse increasing unit increases the amount of pulses from MPU for a predetermined time to pulses capable of measuring the arterial blood oxygen saturation.
