Transcutaneous Po2 Monitoring in Routine Management of Infants and Children With Cardiorespiratory Problems

Abstract

Results are reported concerning the clinical application of the transcutaneous Po₂ method (tc Po₂ method) according to Huch et al. for monitoring arterial Po₂. Thirty long-term continuous tc Po₂ recordings were made in 22 ventilated children and infants with cardiorespiratory problems in four different pediatric intensive care units (Zürich, Göttingen, Kassel, and Mainz). These recordings were compared with 132 arterial Po₂ determinations made during the same period of time. There was a linear relationship and a close correspondence between arterial Po₂ and tc Po₂ (r = .94). The continuous recordings have shown that the variability of Po₂ is much greater than assumed so far by single blood gas analysis. This fact restricts greatly the value of single samples. Continuous tc Po₂ monitoring has proved to be a great help in optimal respirator setting.
