Artificial rupture of membranes (ARM) means means breaking your waters.
Once your cervix has thinned down and dilated to about two to three centimetres we will be able to break your waters. This is done on labour ward by performing a vaginal examination and inserting a small plastic hook and putting pressure on the bag of membranes around the baby to make a hole. Once this is done, we will usually allow you a couple of hours to mobilise in order to bring on contractions.
