The partograph is a simple single page monitoring tool for the first stage of labor.   The tool allows the trained birth attendant to monitor the progress of labor, the mother and the fetus, hour by hour and to have a clear means of tracking whether labor is obstructed--with 'alert' and 'action' lines signaling when a labor has become complicated.   The tool was modified by the WHO and reintroduced in a simpler form. 

Nevertheless, its use is not consistent and training with the partograph is sporadic in many settings.
