During which stage of labor does the cervix dilate from 4 to 7 cm?

The active phase of labor is characterized by a significant acceleration in the progress of cervical dilation and is defined as the stage where the cervix dilates from 4 to 7 cm. During this phase, contractions typically become more frequent, intense, and regular, which aids in the further effacement and dilation of the cervix. This is a crucial stage where the laboring individual may feel an increase in discomfort, and the focus becomes more centered on the management of pain and preparation for the upcoming stages of delivery.

The active phase usually follows the early phase of labor, in which dilation occurs more slowly (from 0 to 4 cm), and precedes the transition phase, where dilation moves from 7 to 10 cm and contractions become even more intense and closer together. The second stage of labor refers to the time from complete cervical dilation to the delivery of the baby, and is not associated with the dilation measurements mentioned. Understanding these stages is vital for monitoring labor progression and supporting the person giving birth effectively.
