Implication

Validation study reveals reliable arterial trend tracking with a transcutaneous oxygen and carbon dioxide monitor in intensive care adults, indicating utility as a noninvasive monitoring adjunct.

Key Points

To evaluate the clinical performance and trend-tracking reliability of a single sensor designed to simultaneously measure transcutaneous oxygen and carbon dioxide tensions compared with arterial blood gases.
Prospective observational study analyzing 514 simultaneous transcutaneous and arterial blood gas measurements in N=47 adult intensive care unit (ICU) patients.
Simultaneous continuous readings of transcutaneous oxygen (PtcO2) and carbon dioxide (PtcCO2) tensions were directly compared against arterial oxygen (PaO2) and carbon dioxide (PaCO2) tensions.
Mean transcutaneous carbon dioxide tension aligned closely with arterial tension, yielding a standard error of the estimate (SEE) of less than 4 torr, whereas mean transcutaneous oxygen tension was considerably lower than arterial oxygen tension.
Directional changes tracked closely, as PtcO2 shifts exceeding 15 torr and PtcCO2 shifts exceeding 5 torr virtually always indicated corresponding increases or decreases in PaO2 and PaCO2.
