2 Fetal Breathing Movements: Trends, Apneic Intervals and Tuning or Less with Other Motions Fetal Breathing Movements: Trends, Apneic Intervals and Tuning or Less with Other Motions Real-time ultrasounds have revolutionized our knowledge of human fetal breathing. Animal preparations too, with the possibility of various forms of otherwise impossible experimentation, have been of paramount importance for our understanding of prenatal breathing. On the other hand, technological advances such as 4D ultrasonography have not added to our knowledge of fetal breathing movements, as these are too fast to be captured by computerized reconstruction.
