IRON LUNGS Meaning and
Definition
-
Iron lungs, also known as tank ventilators or negative pressure ventilators, are mechanical devices designed to assist individuals with respiratory insufficiency, particularly those affected by polio or conditions that impair the functioning of the muscles responsible for breathing. The term "iron lungs" stems from the cylindrical shape of the devices, which resemble large metal barrels.
An iron lung operates by creating negative pressure around the patient's chest, which helps to stimulate breathing and expand the lungs. The patient lies inside the sealed chamber with only their head exposed, and the pressure changes inside the chamber in response to their breathing. When the patient inhales, the negative pressure created pulls air into their lungs, expanding them. Subsequently, when the patient exhales, the pressure decreases, allowing the air to flow out.
Iron lungs were primarily used during the mid-20th century, especially during the polio epidemic. They provided a temporary solution for individuals affected by paralysis of the respiratory muscles, enabling them to breathe while their bodies recovered. These devices were instrumental in saving numerous lives and significantly reducing mortality rates associated with polio.
The advent of positive-pressure ventilators and advancements in respiratory support technology gradually rendered iron lungs obsolete. Nevertheless, their impact on medical history cannot be undermined, as they represent an important milestone in the development of respiratory care and life-sustaining devices.

Etymology of IRON LUNGS
The term "iron lung" is derived from combining the words "iron" and "lung".
The word "iron" refers to the material used in the construction of the device. Iron is a strong and sturdy metal, implying the robust construction of these machines.
The word "lung" originates from the Old English word "lungen", which means "light organ" or "respiratory organ". It has been used historically to refer to the pair of organs responsible for respiration in humans and many other animals. In this context, "lung" implies the purpose of the device - to assist in breathing for individuals with compromised lung function.
When combined, "iron lung" refers to a specific type of ventilator or breathing apparatus that encases a person's entire body, except for the head, and provides mechanical assistance for breathing. It was primarily used for patients with polio who experienced paralysis of their respiratory muscles.
