Comment

Normal baseline heart rate, normal variability, accelerations present and normal uterine activity after Oxytocin infusion was stopped.

Hyperstimulation with oxytocin gives no time for recovery between contractions. There will be an accumulation of carbon dioxide, resulting in a drop in pH.
