This document discusses the stages of labor and how they are recorded on a partogram. It describes the normal progression through each stage of labor (latent phase, active phase, second stage) and defines what constitutes abnormal progression based on alert and action lines on the partogram. Causes of abnormal progression are outlined, including prolonged latent phase, primary dysfunctional labor, secondary arrest, and prolonged second stage. The key information recorded on the partogram is also summarized.
