To investigate the effect of increasing gestational and postnatal age on the relation between transcutaneous oxygen tension (tcPO2) and arterial oxygen tension (PaO2) 160 simultaneous measurements of tcPO2 and PaO2 tensions were made on 42 infants born at 24-41 weeks' gestation and aged 0-32 weeks from birth. Irrespective of gestational age a progressive fall in the tcPO2:PaO2 ratio with increasing postnatal age was found. At all postnatal ages tcPO2:PaO2 tended to be lower in the more mature infants.
为研究孕龄和出生后年龄增加对经皮氧分压(tcPO2)与动脉氧分压(PaO2)之间关系的影响,对42例孕24 - 41周出生、出生后0 - 32周龄的婴儿进行了160次tcPO2和PaO2的同步测量。无论孕龄如何,均发现随着出生后年龄的增加,tcPO2:PaO2比值逐渐下降。在所有出生后年龄,较成熟的婴儿tcPO2:PaO2往往更低。
