Type of Forceps

Outlet, low, mid or high
The accepted clinical standard classification system for forceps deliveries according to station and rotation was developed by ACOG and consists of:

Outlet forceps delivery, where the forceps are applied when the fetal head has reached the perineal floor and its scalp is visible between contractions.[8] This type of assisted delivery is performed only when the fetal head is in a straight forward or backward vertex position or in slight rotation (less than 45 degrees to the right or left) from one of these positions.[9]
Low forceps delivery, when the baby's head is at +2 station or lower. There is no restriction on rotation for this type of delivery.[9]
Midforceps delivery, when the baby's head is above +2 station. There must be head engagement before it can be carried out.[9]
High forceps delivery is not performed in modern obstetrics practice. It would be a forceps-assisted vaginal delivery performed when the baby's head is not yet engaged.[9]
