The document discusses the second stage of labor, also known as the pushing stage. It begins with full cervical dilation of 10cm and ends with the birth of the baby. The duration is typically 2 hours for primigravida women and 30 minutes for multigravida women. It involves three phases: latent phase where the fetus descends passively 2cm; active phase where the fetus descends from the pelvic floor to the vaginal outlet; and transition phase where the baby is born. Proper maternal expulsive efforts and positioning can aid a smooth second stage of labor.
