Baby falls away from the sacrum, allowing posterior shoulder to be born more easily. Baby is not going to slide up toward the diaphragm, because the head is caught OUTSIDE the vagina. Pressure on the diaphragm in McRoberts comes from mom being more firmly curled around the baby with her hips hyperflexed and spine curled up.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
