Uterine contraction intervals and transcutaneous levels of fetal oxygen pressure
Continuous intrauterine transcutaneous PO2 (tcPO2) measurement was performed in 30 deliveries. The various characteristics of labor (peak of contractions, duration, and contraction interval) were correlated with the tcPO2 integral. The best correlation was seen between the tcPO2 integral and that of the contraction intervals. As the data show significant correlations with the pattern of labor, continuous tcPO2 measurement is a reliable and sensitive method for recognizing PO2 alterations early, especially in high-risk deliveries.
