Abstract We evaluated a new combined sensor for monitoring transcutaneous carbon dioxide tension (PtcCO2) and oxygen tension (PtcO2) in 20 critically ill newborn infants. Arterial oxygen tension (PaO2) ranged from 16 to 126 torr and arterial carbon dioxide tension (PaCO2) from 14 to 72 torr. Linear correlation analysis (100 paired values) of PtcO2 versus PaO2 showed anr value of 0.75 with a regression equation of PtcO2=8.59+0.905 (PaO2), while PtcCO2 versus PaCO2 revealed a correlation coefficient ofr=0.89 with an equation of PtcCO2=2.53+1.06 (PaCO2). The bias between PaO2 and PtcO2 was −2.8 with a precision of ±16.0 torr (range, −87 to +48 torr). The bias between PaCO2 and PtcCO2 was −5.1 with a precision of ±7.3 torr (range, −34 to +8 torr). The transcutaneous sensor detected 83% of hypoxia (PaO2 〈45 torr), 75% of hyperoxia (PaO2 〉90 torr), 45% of hypocapnia (PaCO2 〈35 torr), and 96% of hypercapnia (PaCO2 〉45 torr). We conclude that the reliability of the combined transcutaneousPo 2 andPCo 2 monitor in sick neonates is good for detecting hypercapnia, fair for hypoxia and hyperoxia, but poor for hypocapnia. It is an improvement in that it spares available skin surface and requires less handling, but it appears to be slightly less accurate than the single electrodes.
