Comments

At 12:30 the CTG pattern changes, decelerations turns into accelerations at every contraction. The midwife decides to perform an ARM and apply the FSE. When using the FSE  the decelerations are coming back.  If you have accelerations during every contraction you should always be suspicious that it may be maternal pulse. In this case maternal pulse is registered between 12:30-12:48.
