Portable 'Iron Lung' Perfected--This new portable "Iron Lung"--made of plastic--has been perfected for use by polio victims and others needing artificial respiration aid. It weighs less than 60 pounds compared with 600 to 2300 for the ones now in use, and permits the patient to sit or stand. Here Nurse Minnie Malek adjusts the breathing aid on "patient" Barbara Johanson.
