Transcutaneous PO2 poorly estimates arterial PO2 in adults during anesthesia.
We compared values of PaO2 and transcutaneous PO2 in 21 adult patients during anesthesia. In 282 simultaneous determinations during anesthetic periods of 3-10 h, transcutaneous PO2 was a poor predictor of absolute PaO2 and changes in PaO2. Transcutaneous PO2 monitoring in adults during anesthesia is of unproven value.
