Transcutaneous monitoring of PO2 in different skin areas in the neonate and in the scalp of the fetus during labor - methodological and physiological observations.
The reliability and physiological significance of continuous non-invasive PO2 recording by means of skin electrodes was studied by comparing simultaneous tracings from different skin areas in a series of 40 newborns with normal labor and birth. A new measuring equipment - the Radiometer prototype unit TPM 1 - was used. In addition, the applicability of the method to the fetus was tested in a primary series of 11 labor cases. Certain technical and physiological factors that can influence the tracings were identified.
