Kennedy and Jacqueline Kennedy Onassis-died from prematurity at 34 weeks' gestational age, yet by 1971, the Schaffer and Avery textbook Diseases of the Newborn stated that "the lower limit of viability is probably about 28 weeks" due to advances in respiratory therapies, thermoregulation, and nutrition 3 By the 1990s, large prospective cohort studies demonstrated a 50% survivability at 24 weeks' gestational age, 1 and recently centers have shown greater than 60% survivability in infants born at 22 weeks' gestational age. 4 Hyland et al 5 have provided data on a cohort of infants at the University
