Objective:
To assess the correlation between the total deceleration area of the fetal heart rate (FHR) pre-delivery trace and intrapartum fetal acid-base status in a low risk population.
Study Design:
We analyzed the electronic fetal monitoring (EFM) traces of 26 pregnancies with fetuses presenting acidemia at delivery and those of thirty controls. All laboring patients had at least 1 hour of EFM without interruption. The deceleration area was calculated, after digital analysis, with Autocad System 2004.
Results:
We found that the number of decelerations (8.03 +/- 3.77 vs. 4.64 +/- 3.84) and the total deceleration area/hour (35.56 +/- 11.87 vs. 17.81 +/- 9.38) were significantly higher in the study group than in the control group.
Conclusions:
Our results show that quantitative analysis of the deceleration areas by digitized cardiotocography may have a discriminative capacity to predict fetal acidemia at delivery.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and HCO3− values are examined to...
