Transcutaneous arterial oxygen saturation (TcSaO2) and directly measured oxygen saturation values from 25 neonates with a variety of respiratory problems were compared. At arterial oxygen saturations above 60 per cent, TcSaO2 measurements were accurate and reliable. However, SaO2 values less than 60 per cent were significantly overestimated by TcSaO2, so careful laboratory confirmation of low SaO2 values is necessary. The use, accuracy, and limitations of this noninvasive transcutaneous technique for measuring arterial hemoglobin-oxygen saturation are discussed.
