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• Completely replacing the legacy 1950s Friedman Curve and the outdated WHO Partograph.

Latent phase continues until 5 cm of cervical dilation. The active phase is strictly defined as 5 cm to 10 cm. Interventions to accelerate labor should NOT routinely be performed before 5 cm.

• Do not routinely perform amniotomy (breaking the water) or start Oxytocin just because the latent phase (< 5cm) is prolonged, provided maternal/fetal signs are stable.
• ACOG guidelines (US) differ slightly by defining the onset of the active phase at 6 cm, structurally allowing even more conservative management in the 4-5 cm window compared to the global WHO 5 cm rule.
• Epidural analgesia routinely adds 1-2 hours to the active phase; thresholds must be mentally adjusted.

• Progress crosses the established maximum time limit for the specific centimeter increment.
• Perform thorough assessment of the 3 P's: Power (contractions), Passenger (fetal position/size), Pelvis.
• If contractions are inadequate: Consider Artificial Rupture of Membranes (AROM) and Oxytocin augmentation.
• If adequate contractions (>200 Montevideo units) persist for 4 hours with no cervical change in the active phase: Arrest of active labor. Proceed with Cesarean delivery.

In 1955, Dr. Emanuel Friedman studied 500 women and created the "Friedman Curve." For 60 years, it was undisputed dogma. However, modern women are older, have higher BMIs, larger babies, and widely use epidurals, rendering the 1950s data highly dangerously inaccurate and triggering an epidemic of premature cesarean deliveries.
