6. Average maximum physiological changes associated with Pregnancy Parameter Change Neurologic MAC (minimum alveolar concentration )
7. Average maximum physiological changes associated with Pregnancy Parameter Change Neurologic MAC (minimum alveolar concentration ) - 40% 1.(MAC) progressively decreases during pregnancy—at term, by as much as 40%—for all general anesthetic agents 2.MAC returns to normal by The third day after delivery.
