There are two phases: (1) the passive stage during which the fetus descends through the maternal pelvis, and (2) the active phase of maternal pushing. The duration of the normal second stage of labor is mainly influenced by parity and the presence of an epidural. The median durations of the second stage are given in Table 16-1, but there is a large range in duration.
