Evolution of Ventilation

The journey of mechanical ventilation began with Alfred's negative pressure devices in the 1860s, which were touted as cures for a variety of ailments, including asthma and even deafness. The iconic iron lung, developed by Philip and Lewis in the late 1920s, became essential during polio outbreaks, providing life-saving support. A touching moment highlights the first patient's recovery, as a young girl emerged from the device asking for ice cream, showcasing the profound impact of this medical innovation.
