ABSTRACT
If the infant requires a very modest increase in the inspired oxygen concentration (25 percent), this can be achieved by administering the oxygen-rich inspired gas into the incubator. In practice, however, every time the incubator portholes are opened there will be a sudden drop in the oxygen concentration. If the infant requires an increased inspired oxygen fraction, 0.25, the oxygen should be given into a perspex box placed over the baby’s head and shoulders (headbox). The oxygen concentration should be continuously monitored by an analyzer placed near the baby’s mouth. The oxygen should be humidified.
