Neonatal mortality increases with altitude. For example, in Peru the incidence of neonatal mortality in the highlands has been shown to be about double that at lower altitudes. An important factor is the low inspired PO2 of newborn babies. Typically, expectant mothers at high altitude will travel to low altitude to have their babies if possible, but often this is not feasible because of economic factors. The procedure described here raises the oxygen concentration in the air of rooms where neonates are being housed and, in effect, this means that both the mother and baby are at a much lower altitude. Oxygen conditioning is similar to air conditioning except that the oxygen concentration of the air is increased rather than the temperature being reduced. The procedure is now used at high altitude in many hotels, dormitories and telescope facilities, and has been shown to be feasible and effective.
新生儿死亡率随海拔升高而增加。例如，在秘鲁，高地新生儿死亡率已被证明约为低海拔地区的两倍。一个重要因素是新生儿吸入的氧分压较低。通常情况下，高海拔地区的准妈妈会尽可能前往低海拔地区分娩，但由于经济因素，这往往不可行。这里描述的方法提高了新生儿所在房间空气中的氧气浓度，实际上，这意味着母亲和婴儿所处的海拔要低得多。氧气调节类似于空调，只是空气的氧气浓度增加而不是温度降低。该方法目前在许多高海拔地区的酒店、宿舍和望远镜设施中使用，并且已被证明是可行和有效的。
