To provide an oxygen concentration control apparatus for incubators suited to a continuous use over a long period of time.
A pulse oximeter 14 measures an arterial oxygen saturation (SpO2) of a stored infant 13 stored in an incubator 11, and a control device 15 finds an inspired oxygen concentration (FiO2) 26 for making the measured value 24 of the arterial oxygen saturation (SpO2) by the pulse oximeter 14, a predetermined setting value 25. The measurement of the arterial oxygen saturation (SpO2) by the pulse oximeter 14 dispenses with the heating of a skin of a measurement object site, so that even if the arterial oxygen saturation (SpO2) is continuously measured over a long period of time, the possibility that the stored infant 13 gets low-temperature burn is low.
