Unveiling the Secrets of the Iron Lung: A Symbol of Medical Triumph and Resilience
The Marvelous Machine
The iron lung, a bulky apparatus that resembles a metal coffin, was a medical marvel that played a pivotal role in saving the lives of polio patients during the early 20th century. Despite its intimidating appearance, this ingenious invention provided a lifeline to countless individuals whose breathing was paralyzed by the dreaded disease.
How the Iron Lung Works
The iron lung operates on the principle of negative pressure ventilation. It encloses most of the patient's body within an airtight chamber, with only the head and neck remaining exposed. Inside the chamber, the air pressure is lowered, causing the patient's chest to expand and draw air into the lungs. Conversely, when the pressure is increased, the chest contracts, expelling air from the lungs.
