The continuous monitoring of the PO2 with double sensors, pre- and post-ductal, is very interesting during the neonatal period; the magnitude of the right-to-left ductal shunting, related to high pulmonary vascular resistance, is well evaluated by the hyperoxemia test. This noninvasive method allows a reliable observation of the pulmonary vascular response to oxygen, alkaline solutions, or tolazoline infusion.

Simultaneous transcutaneous oxygen tension and tissue pH monitoring in sick neonates.
Our studies show that simultaneous tcPO2 and tpH monitoring is feasible and they indicate a highly significant degree of correlation between arterial PO2 and tcPO2 on the one hand and arterial pH and tpH on the other. We also conclude that tissue pH as measured with tpH electrode is a close approximation of arterial pH in sick neonates.
