As participants in the clinical field trials in the United States for the Roche 5301 transcutaneous oxygen monitor, we report here the results of our experience for comparison with that reported by Meith and colleagues in an earlier Letter (Pediatrics 58: 299, August 1976). The Roche model 5301 differs from the previously tested model 5300 in that the oxygen sensor has been modified and the electrode operates at 44 C instead of 42 C.
Thirty-two newborn infants of 28 to 39 weeks' gestational age and 560 to 3,700 gm birth weight were monitored while they experienced respiratory illness caused by idiopathic respiratory distress syndrome, pneumonia, or apnea.
