Station:
 Station refers to the relationship of the presenting part to an imaginary line

drawn the ischial spines of the maternal pelvis. The ischial spines as a
landmark have been designated as zero station. If the presenting part is
higher than the ischial spines, a negative number is assigned, noting

centimeters above zero station.
Station –5 is at the inlet, and station +4 is at the outlet. If the presenting part
can be seen at the woman perineum, birth will occur momentarily. During labor,
the presenting part should move progressively from the negative stations to the
midpelvis at zero station to the positive stations.
