To record the maternal and fetal data during labor on a single sheet of paper. This is the main purpose of using a partograph, which is a tool for monitoring maternal and fetal wellbeing during the active phase of labor, and a decision-making aid when abnormalities are detected.

Measuring the blood pressure and temperature of the mother every hour is only one of the maternal indicators that are recorded on the partograph, along with heart rate, time of rupture of membranes, uterine contractions, urine output and drugs administered.

Calculating the estimated date of delivery and gestational age of the fetus is not done using a partograph, but rather using other methods such as ultrasound or last menstrual period.

diagnosing the cause of prolonged and obstructed labor is not the main purpose of using a partograph, but rather a possible outcome of interpreting the partograph.

The partograph has two diagonal lines: an alert line and an action line. If the dilation curve crosses the action line, decisions must be made (augmentation of labor, artificial rupture of membranes, cesarean section, etc.).
