During the active phase of labor, cervical dilation typically progresses from 4 to 8 centimeters. This phase is critical as it indicates that labor is intensifying and contractions are becoming more frequent and stronger.

Understanding the stages of labor is essential for both expectant mothers and healthcare providers. The initial latent phase can involve dilation from 0 to about 3 centimeters, where contractions may be irregular and less intense. During the active phase, which begins at approximately 4 centimeters, dilation accelerates as the body prepares for delivery.

This phase culminates at 8 centimeters, leading into the transition phase where the cervix dilates from 8 centimeters to fully dilated at 10 centimeters. Recognizing these milestones helps in monitoring progress and identifying any potential complications during labor. Properly identifying the active phase allows for timely interventions and support for the mother as she approaches the birthing process.
