Labour Progress (WHO)

WHO Labour Care Guide

FIGO Standard Partograph Monitoring

Success/Alert Thresholds

Active First Stage≥ 5cm Dilation

Normal Rate≥ 1cm / 2 hours

Second Stage (Para 0)Max 3 Hours

Second Stage (Para 1+)Max 2 Hours

Uterine Dynamics

Target: 3-4 contractions per 10 minutes, each lasting 40-50 seconds in the active phase.

Tachysystole Alert

> 5 contractions per 10 mins (Averaged over 30 mins)

The World Health Organization (WHO) has replaced the traditional 4-hour action line with a 1cm per 2-hour action limit to reduce unnecessary interventions.

Guidelines & Evidence

When to Use

Primary Clinical Uses

Continuous monitoring of intrapartum maternal and fetal well-being.

Identifying prolonged or obstructed active labor to trigger interventions (amniotomy, oxytocin, cesarean).

Completely replacing the legacy 1950s Friedman Curve and the outdated WHO Partograph.

The Paradigm Shift

The rigid "1 cm per hour" rule is dead. Modern evidence shows that physiological labor is entirely non-linear. The WHO Labour Care Guide (LCG) dictates that active labor does not begin until 5 cm of dilation, and allows for significantly slower early progress without intervening.
