Artificial Rupture of Membranes (ARM) is a medical procedure performed during labor to intentionally break the amniotic sac, which contains the fluid surrounding the baby. This is usually done using a sterile instrument called an amnihook. The primary purpose of ARM is to help speed up labor or to monitor the baby's condition more closely. The procedure is typically safe and can be performed by a qualified healthcare provider, such as an obstetrician or midwife. After the membranes are ruptured, the healthcare team can assess the color and consistency of the amniotic fluid, which can provide important information about the baby's health.
