Teaching the progression of cervical dilatation is easy with this innovative model. The model's ten removable rings depict each centimeter of dilatation from 1 cm-10 cm. Each ring is color-coded to represent its corresponding phase of labor. The rings depicting 1 cm-3 cm of dilatation are blue to represent early labor, the rings depicting 4 cm-7 cm of dilatation are yellow to represent active labor, and the rings depicting 8 cm-10 cm of dilatation are pink to represent transition. Can also be used to discuss cervical effacement.
