When contractions occur, the baby cannot rest/breathe. The longer the contractions the more danger it is causing the baby. Pitocin (oxytocin) should not be given if contractions lasts longer than 60 seconds and not more frequently than 1.5 minutes apart. Although it can induce, augment, and help shrink the uterus after the placenta is expelled. Carefully watch your contractions if you are being given Pitocin.
