The term “one to ten fingers” refers to the degree of dilatation of the cervix. Commonly known as the first finger, usually 1cm, it is a unit of length and is used to indicate the length of dilation of the cervix during labor. One finger is usually 1cm, while ten fingers are usually 10cm. Clinically, the number of fingers is used to describe the size of the dilation of the cervix during labor and to determine the progress of labor, in order to help the mother better understand her environment and the progress of the labor, as well as to determine the success of the labor. Generally speaking, when the uterus is fully dilated at 10 fingers, the cervical canal is fully dilated and the second stage of labor has begun. The process from the first to the tenth finger is relatively long and depends on the health of the mother and the strength of her labor. For example, if a pregnant woman is more active during pregnancy, she will also have a much easier time during labor and the cervical canal will dilate more quickly. When the labor force is greater the baby’s delivery is also relatively smooth. Therefore, the process of opening one finger to ten fingers represents the progress of labor, and the larger the value, the closer the labor is.
