In the 1910s, the Infant Lungmotor was a small-size device specially made for Asphyxia Neonatorum. No maternity ward was complete without this apparatus.[1]
The infant model had to be used with caution to protect the small, fragile lungs of these patients; but anxious rescuers could pump too forcefully. These devices were condemned by studies which showed that they were liable to do more harm than good.[2]
