Abstract
The present invention provides an oxygen concentration control apparatus for an incubator and an incubator using the same also suitable for continuous use for a long period. A pulse oximeter measures percutaneous arterial oxygen saturation (SpO.sub.2) of a newborn accommodated in an incubator, and a control unit obtains fraction of inspired oxygen (FiO.sub.2) used for setting the measured value of the percutaneous arterial oxygen saturation (SpO.sub.2) obtained by the pulse oximeter to a predetermined set value. In the measurement of the percutaneous arterial oxygen saturation (SpO.sub.2) by the pulse oximeter, it is unnecessary to warm the skin of a region to be measured. Consequently, even if the percutaneous arterial oxygen saturation (SpO.sub.2) is measured continuously for a long period, there is low possibility that the accommodated newborn suffers a cold burn.
