A set of color coded rings consisting of one subset of even numbers and other subset of odd numbers together is indicative of serially increasing cervical dilatation from 4 cm. to 9 cm. Vaginal examination with all aseptic precautions is to be carried out every 2 to 4 hours for each delivering woman. Size and color of the ring corresponding to actual cervical dilatation is to be identified. Next ring of the same color indicates expected cervical dilatation at the end of every 2 hours. If the expected cervical dilatation is not reached within the stipulated period of time, it indicates slow progress of labor and need for intervention/referral.
