This study is an evaluation of different methods of Po 2 monitoring in newborn infants. These were an intra‐vascular Pb 2 electrode (Searle Life Support Systems); transcutaneous monitoring (Kontron and Hewlett‐Packard); and arteriatized capillary blood samples. Values of each were compared with simultaneous aortic sample values and their correlation compared. The Searle electrode and TCM were found to be of equivalent accuracy overall, although the Searle was less reliable. Searle catheters were more difficult to insert than normal catheters, with a high wastage. Arterialized capillary Po 2 values did not correlate with arterial. Transcutaneous monitoring is the most reliable and cheapest method.
