WHO Simplified Partogram

Plot cervical dilation and fetal descent on the 1994 WHO Simplified Partograph grid, with Alert and Action line checks, contraction shading, and maternal/fetal vitals. A bedside recording aid for the WHO grid, not a diagnosis or management decision. Observations stay on this device.

How the WHO Simplified Partograph works

The Simplified Partograph starts at the active phase of labour (≥4 cm dilation). Cervical dilation is plotted against elapsed hours; a straight Alert Line marks expected progress of 1 cm per hour from 4 cm to 10 cm. An Action Line sits parallel, four hours to the right. Points to the right of the Alert Line flag slow progress; points on or beyond the Action Line are a published cue for the attending obstetrician to re-evaluate labour and escalate care as clinically indicated.

Alongside the dilation curve, the chart records descent of the fetal head, fetal heart rate, amniotic fluid and moulding, contraction frequency and duration, oxytocin or other drugs, and maternal pulse, blood pressure, and urine findings. This free tool mirrors that bedside worksheet in the browser so a clinic can practise plotting or print a dated blank for the labour room.

Many labour rooms still keep this on paper. If you run an obstetric practice, our OB-GYN clinic workflow page explains how Avinya Plus's template builder and formula engine let you build partograph fields into a labour form and keep the plotted vitals on the note. Avinya Plus ships no pre-built obstetric instrument; you configure it, and the arithmetic is the engine's.

Frequently asked questions

What is a Partogram (or Partograph)?
A partogram is a graphical recording of labor progress, including cervical dilation and fetal descent over time, alongside key fetal and maternal vitals. It is used to monitor labor and detect abnormalities or delays early.
How do the Alert and Action lines work on the WHO Partograph?
The Alert Line represents a normal progress rate of 1 cm per hour in the active phase of labor (starting at 4 cm dilation). The Action Line is drawn parallel to the Alert Line, exactly 4 hours to the right of it. Crossing the Alert Line signals slow progress that warrants closer monitoring and transfer planning; crossing the Action Line is a published cue for the attending obstetrician to re-evaluate and decide on further management.
At what point in labor should the Partogram be started?
The partogram is designed to monitor labor during its active phase, which is defined as starting when the cervix is at least 4 cm dilated and uterine contractions are regular.
How are uterine contractions measured on a Partogram?
Uterine contractions are assessed every half-hour by counting the number of contractions that occur within a 10-minute window, and noting their duration: mild (less than 20 seconds), moderate (20 to 40 seconds), or severe (more than 40 seconds).
Does the entered patient data leave my browser?
No. All calculation and data storage run completely client-side in your browser. No patient records or clinical metrics are sent to any server. You can safely print or save the worksheet as a PDF for clinical use.

Sources

Alert and Action line geometry and observation rows follow the WHO Simplified Partograph (WHO/MCH/94.2.Rev.1). Crossing a line is a published monitoring cue, not a prescription. Reviewed against the source on 2026-07-14. Verify against current FOGSI / national / institutional labour guidelines.

This partogram tool is a bedside recording aid and clinical arithmetic tool. It does not provide medical diagnoses, make clinical decisions, or prescribe obstetric actions. All records are computed in your browser; no patient data is uploaded or stored.

Build the labour chart into the record.

In Avinya Plus you can build partograph fields into a labour or antenatal template with the template builder, keep structured patient records exportable, and run GST-compliant billing for the same visit. See it on a quick demo.
